- "All gates of the well sealing device must be tested for pressure." The supervisor gave an unequivocal order.
Lu Xiangfei, the drilling captain of Dahua 505, said bitterly: "There are more than 200 gates. If we try like this, we can't finish them in one day. In fact, the standard of our blowout preventers is higher than other companies, and now the time is so tight. , how about we test the main gates and randomly check 10 more?"
"Our standards are high, and the oil and gas pressure in the Aqijiu Oilfield is higher. If there is another blowout, we will all be in trouble. Last time, you didn't know about the accident where the entire derrick flew into the sky? If it hadn't been for the explosion-proof protection of the drilling platform If the level reaches level 2, the drilling platform may be on fire. I will let you go here, but you will still fail the subsequent inspections." The supervisor is also an employee of Dahua Industrial. Although he is on the drilling platform with the drilling team, he and the drilling team The team is divided into two units, which is equivalent to the existence of Party A. It supervises Party B full-time and requires the other party to complete the work according to the prescribed steps and documents.
In the current Setan Oilfield, or in the several oil fields developed by Dahua Industrial for the Russians, there are a large number of drilling teams from the National Petroleum Corporation as Party B for Dahua Industrial, which is a pure construction party. There were originally many construction teams from Party B in the Aqijiu Oilfield, but only because of Su Cheng's order, they were all replaced by Dahua's own teams.
However, the construction personnel have changed, but the system structure has not changed substantially. Not only that, because Sioux City is closely watching, Dahua employees across the region are very careful, and the rules and regulations of production safety are like golden rules. Hanging in the air, a few people dare to touch it. Even if you are not fired, you will still have to be demoted or sent back to your country for retraining.
Lu Xiangfei finally climbed onto the "special contribution list", so naturally he didn't want to be kicked off because of disciplinary violations. He gritted his teeth and said: "The pressure test standard is high. There must be valves that can't withstand it. The materials we currently have in stock are not enough. We have to ask the supply ship to deliver things now. If they are not available in the warehouse, they must be bought now."
"No problem." The supervisor was very clear about his responsibilities and agreed.
"I can't sleep now." Lu Xiangfei sighed. I went back and gave the order, and I kept my head down and did it first.
The drilling team members were wailing, but it had no effect. He had no choice but to follow Lu Xiangfei and start debugging.
The drilling platform 505 uses an annular well sealing device. The rubber core is a big weak point. It all depends on the technique. If it is used well. It can reach a pretty good level.
Lu Xiangfei serves as the captain. Naturally, the technology is the best. He personally went into battle and inspected and debugged more than 200 gates in sequence. It was originally expected to start drilling in the afternoon, but it naturally failed. In fact, by dinner time, only the second round of inspections was completed.
"Can we try it?" The supervisor was also anxious. Asking the entire drilling platform to follow the rules was his first priority. But time is also very important. Everyone in China knows that the company has invested a lot in Azerbaijan. It costs a lot for people to eat horse chews. If safety regulations had not been issued frequently, he would have started drilling as soon as possible.
Lu Xiangfei read it again, wiped his sweat, straightened up and said, "Just try it, make preparations first."
Without him having to say it alone, the plug, clean water, and sealing rubber ring were instantly put in place, and the high-pressure area was also surrounded by a warning tape. The driller and deputy driller were holding mud pumps and hoses, as if they were ready for disaster.
Lu Xiangfei and the driller installed a cleaning head on the weighted drill pipe together. After cleaning the wellhead, they went down into the well and connected a plug with butter on the upper end
When everything was ready, Lu Xiangfei shouted directly in a hoarse voice: "Close the valve and apply 10 pressures first."
? 10 pressures are 10 atmospheres, which is approximately equal to 1 MPa, which is a relatively small wellhead pressure.
The well sealing device performed well under this value, which also proved that there was no problem with the installation. Lu Xiangfei nodded and said again: "The mud pump reaches 30 pressures."
The driller did as he was told, and the engineer held his pocket watch and shouted: "Record the 3 MPa stabilized voltage for 10 minutes, start timing."
Lu Xiangfei sat down on a raised edge with a relaxed expression.
The well sealing device they are using now is self-produced by Dahua Industrial. It is not as good as the imported products from Setan Oilfield, but it is still much better than domestic products. This is also determined by the different working environments. Several domestic companies rarely go abroad to do projects. The pressure of domestic oil wells is small, and a similar well capping device will suffice. Sioux City, on the other hand, is obsessed with occupying several large oil fields and has high requirements for various self-produced oil well equipment.
Historically, China National Petroleum Corporation began to encounter problems with well sealing equipment when extracting Sudanese crude oil. However, before that, they often used imported goods.
3 MPa is extremely easy for any well sealing device.
After 10 minutes of voltage stabilization was completed, the driller asked Lu Xiangfei for instructions, and then talked to the deputyThe driller slowly increased the pressure of the mud pump to 20 MPa.
Lu Xiangfei just stood up at this time.
The supervisor also stretched his neck and held his watch to check the time.
As soon as the hour hand reached three minutes, mud began to gush under the gate.
"Is it okay?" The supervisor turned to Lu Xiangfei and asked, this level is not too bad, it is still on the edge of being usable.
Lu Xiangfei scratched his head: "Look again."
At the end of the 10-minute voltage stabilization test, the gate did not explode, but the rubber core could not go back when it was closed.
Lu Xiangfei said predictably: "The mat is no longer working, and this well sealing device needs 200 pressures. I have to replace it with a new one to have any hope."
"I'm going to call the supply ship." The supervisor went to make a call without saying anything.
At 12 o'clock in the morning, it was Dahua's own night ship that rushed over the needed supplies. At this time, even if they did not pursue confidentiality, the Azerbaijanis in Baku would not sail out.
The supervisor went to inspect the materials on behalf of Party A. Lu Xiangfei had already removed all 48 one-inch three-inch screws. Not only members of the drilling team, but also workers and engineers from other departments rushed over to help, either by adjusting the derrick, or by helping to change mats and apply oil.
Try again, the annular well sealing device lasted for 5 minutes under 200 pressure, and the rubber core broke again.
"Change again." Lu Xiangfei looked like an old scalper. Only when the well sealing device reaches its best working condition can it withstand 200 atmospheres of pressure.
48 large screws were removed again, and all the pads were replaced. Re-grease and reinstall the gate.
Several workers lay on the ground and worked for more than an hour before adjusting the huge screws in place. Lu Xiangfei checked one after another. To achieve the maximum effect, the screws were either too tight or too loose. In the most particular precision machining workshops, there are regulations on the number of turns on the screws. Some factories take a year and a half to achieve the yield rate required by the design. This is because they are trying these detailed things.
Offshore drilling platforms do not originally require special precision. However, if you want the equipment to reach its best condition, it must require special precision.
On the sea surface at night, the cold wind does not stop. Even if you wear four or five pieces of clothing. Still couldn't help but stamp my feet, lying on the cold steel surface to load and unload huge screws was definitely a hard job, not to mention that the steel surface was now covered with mud.
It¡¯s hard, tiring and dirty, and this job is basically unacceptable.
The supervisor saw Lu Xiangfei, who was nearly 40 years old, shivering from the cold. He took off his gloves and fumbled to tighten the screws. Feeling really sorry, he simply took off his military coat. He placed himself under Lu Xiangfei's legs and said, "If it doesn't work, let's do it tomorrow. Otherwise, let's purchase a batch of imported well sealing devices."
"The well head also needs to be adjusted. It's not much better. As long as this well can produce oil, I'm happy to do it for two more nights." Lu Xiangfei asked someone to bring another military coat over for the supervisor to put on, and continued to work hard with his head down.
In just a few minutes, the supervisor's lips turned blue from the cold. He put on his clothes in embarrassment and said shivering: "Dr. Su said that the oil field under our feet is one of the best in the world. What we want is , it is the oil well with the largest production. Next time, what comes out from under the sealing device will definitely be crude oil.¡±
"With 200 pressures, if crude oil can still pop out" Lu Xiangfei suddenly laughed twice, then changed the subject and said, "I admit it."
"I admit it too! In my life, the most promising opportunity to see a 10,000-ton oil well is now." The supervisor, wrapped in his coat, suddenly sighed.
An ordinary well with a capacity of 10,000 tons cannot achieve a pressure of 200 atmospheres. Therefore, a high-pressure well that cannot be blocked by a 200-pressure sealing device must be a high-yield oil well.
Although the oil fields occupied by Dahua are good, there are only so many high-yield oil wells in the world. If a company can encounter two, it will be celebrated. When divided into drilling teams, it is really hard to say whose luck is it.
The supervisor¡¯s words made everyone feel something, and their movements naturally became faster.
The third test still failed.
The fourth test still failed.
Each time, all parts have to be removed and gaskets and lubricants reinstalled.
Repetitive and boring work makes people dizzy and almost vomiting.
Lu Xiangfei frowned, but persisted.
The rest of the drilling team gradually lost their complaining mood and continued working along with the captain.
The work on the platform is inherently dirty, tiring and hard. Those who cannot bear the pressure will definitely not be able to stay.
It took a total of 30 hours before the pressure test was successful.
At this moment, the faces of everyone on the entire drilling platform were blank. On the one handThe cold wind blows, which means staying up late.
Lu Xiangfei signed the documents given by the supervisor and went back to sleep. People from other departments tried their best to help clean up. The next work still belongs to the drilling team. They can't do it without a good sleep.
The next day, a smell of fragrance woke Lu Xiangfei up.
"What?" He looked down from the upper bunk. The place on the drilling platform was expensive, and it was basically the same dormitory as the school.
Sitting on the lower bunk was engineer Huang Donglei. This guy with an astonishing belly was digging into his lunch on the plate while muttering: "Dr. Su is here, grab enough rice with your hands, half meat and half rice."
"Dong Su is here?" Lu Xiangfei repeated.
Huang Donglei couldn't understand the point at all. He said "hmm" and said crookedly: "You haven't eaten breakfast or lunch, right? Go quickly. There is still soup in the canteen. If it's later, those wolves will drink all the food."
"Why don't you eat in the cafeteria?"
"There were several senior executives at the headquarters. I ate two portions. I was a little embarrassed, so I said I would give a pot to the drilling captain in the dormitory. Director Su heard this and asked about you. Look, the cook heard that he was giving The rice you get is more meat than others. Oh, if you are asked when you go to the canteen, just say that I knocked over the rice bowl on the way." Huang Donglei said while eating, both items were very fast. quick.
Lu Xiangfei jumped out of bed. He blocked Huang Donglei's waving chopsticks and said, "You said Director Su asked about me?"
"Yeah, I said I'll let you go see him when you wake up. Otherwise, do you think the cook is willing to prepare food for me to bring back? And give me so much meat? Look, it's all short ribs, very likely. Eighty-nine times that guy hid it."
"Dong Su asked me to go see him when I wake up?" Lu Xiangfei was stunned for a moment and said angrily: "Why didn't you tell me earlier?"
"Didn't I say that?"
"I'm going now." Lu Xiangfei put on his pants and picked up his clothes. Just run outside.
Behind him, Huang Donglei said slowly: "Do you know where Director Su is?"
Lu Xiangfei, who had already reached the top speed, braked suddenly, came back and glared at Huang Donglei and said, "Not in the cafeteria anymore? Do you know where it is?"
"Oh. You know." Huang Donglei blinked and lowered his head to eat.
"What do I know?"
"It's in the cafeteria, I thought you didn't know." Huang Donglei looked like a fool.
Lu Xiangfei went crazy and grabbed his chopsticks angrily. Two-step approach. Throw it directly into the sea.
Huang Donglei stood up calmly, opened the drawer, took out a new pair of chopsticks, and said silently: "Fortunately, they are bamboo chopsticks, otherwise they would have caused pollution."
Lu Xiangfei ran to the cafeteria as quickly as possible and saw Su Cheng and his party. The most conspicuous among them was Qin Shiwei, who was thicker than an iron pillar.
"Dean Qin of the Drilling and Oil Production Research Institute? What is he doing here?" Lu Xiangfei saw him. There was a moment of doubt at first, and then there was a surge of ecstasy.
Qin Shiwei is famous for treating time as his life. I would never do anything like socializing or escorting.
With his strong body, superb technical skills and Suzhou City¡¯s attention, Qin Shiwei is as special as an activity boss in the eyes of grassroots workers - wherever he is, it usually means some kind of activity.
¡°On today¡¯s drilling platforms, the only activity is oil production.
"You have a new plan?" Lu Xiangfei was not very awake when he came to Su Cheng and said something out of nowhere.
Su Cheng smiled, took the initiative to shake his hand and said, "Captain Lu, I heard that you have been working for two days and one night in a row. Are you tired?"
"I'm not tired. There's nothing to be tired about. This is what we do." Lu Xiangfei was a little proud. This was the boss giving us a warm welcome.
Qin Shiwei was not prepared to give them time to chat. He knocked on the table and said, "We have been checking the seismic data recently. The edge well we are working on at No. 507 is in good condition. Based on the latest feedback, I have made a new stratigraphic map. You can create a new stratigraphic map." Please refer to it when cleaning the well.¡±
The stratigraphic map in the mid-1990s was quite simple, but the basic functions were still complete, and Lu Xiangfei could understand it. He tilted his head and thought for a while, then said: "So, our lower part is connected with 503?"
"Yes, and if the production here is a little lower, the output may be higher."
"Then I understand."
"As long as you understand, let's go." Qin Shiwei stood up and started collecting the drawings.
Lu Xiangfei didn¡¯t understand again and asked: ¡°Where to go?¡±
"Start drilling!" Qin Shiwei looked even more confused.
"Ahah!" Lu Xiangfei woke up as if from a dream, and quickly followed him, thinking: These engineers from the Petroleum University are all idiots, each one is more unreliable than the last.
Su ChengxiaoHehe nodded around, Shi Shiran followed behind.
Soon, the drilling rig rumbled.
Since Dahua Industrial started drilling in November last year, it has drilled three rounds of drilling, with a total number of more than 10. However, its luck is not very good, and most of them are dry wells. However, with so many oil wells at the bottom, the geological conditions below have been clearly understood. Qin Shiwei's drawing is still a prediction, but once it is confirmed, it will be a standard underground crude oil distribution map.
In fact, the situation that Dahua Industrial encountered in the Aqijiu Oilfield is the most common situation encountered by the oil industry. To be more precise, it is quite good that more than two of the 10 oil wells in the early stage have seen oil.
Only this ratio can allow oil companies to persist. Otherwise, no matter how strong the oil company is, it will drill five dry wells without any oil star. And if you drill more, you will understand the underlying situation, and the probability of finding a dry well will be smaller.
What Lu Xiangfei is doing now is more like a pure oil production well than an exploration well.
Under his command, the drilling team kept accelerating the footage based on the drawings.
On the afternoon of June 16, the drill bit reached the designated location.
"Put the casing in!"
"Test the oil!"
Lu Xiangfei¡¯s drilling team performed a series of actions extremely skillfully.
Qin Shiwei stood in the supervisor's position and stared closely at the actions below. What he wanted was a successful oil test, which would illustrate the accuracy of the crude oil distribution map.
Su Cheng¡¯s mood was equally uneasy, and he said with a poker face: ¡°The situation looks good, you don¡¯t have to worry.¡±
"What do I have to worry about?" Qin Shiwei said covertly: "If it doesn't succeed this time, I will have to explore the side well"
"Don't say unlucky words." Su Cheng interrupted him.
Qin Shiwei was stunned: "Do you still believe this?"
As soon as he finished speaking, the drilling platform vibrated.
The derrick also made a "gurgling" sound, like a burp at the bottom of the sea.
Qin Shiwei was stunned for a moment, his expression instantly changed from a silly smile to a silly expression, like a bear whose face was swollen by a bee sting.
"Oil is out"
Su Cheng murmured, his voice completely covered by the noise in his ears, but his mood was inexplicably calm.
It should be said that he didn¡¯t feel calm before, until now.
The exploitation of the Aqijiu Oilfield really consumed too much of his energy and the group's resources. It was natural to produce oil. However, the dry wells that were not natural caused too much pressure. .
Not only Su City is under tremendous pressure, the entire Dahua Industrial is under tremendous pressure.
Even those who don¡¯t know about the Aqijiu Oilfield are under greater pressure.
After a brief period of dementia, Qin Shiwei rushed up to check. Yang Ming, Li Shirong and others lost their usual calmness and looked ahead at a loss, all looking like they were giddy with joy.
"We need to drill a second oil well immediately, and a third one here and here!" Qin Shiwei ran back at some point, tearing open the drawing with a stain all over his body, and pressed hard on the two key-marked crosses with his fingers. point.
Su Cheng seemed to have been awakened. He nodded twice, then grabbed Li Shirong and shouted at the top of his voice amidst the endless noise: "Keep it secret, keep the oil well secret!"
?¡(To be continued)
ps: I am still in the state of celebrating the New Year and I can¡¯t help myself.
