Chapter 621 The First Confidential Oil Well

"All gates of the well sealer should be tested." The supervisor's resolute order.

Lu Xiangfei, the drilling captain of Dahua 505, was full of bitterness: "There are more than 200 gates. If we try it like this, we can't finish it in a day. In fact, our standard of blowout preventers is already higher than other companies, and now the time is so tight. Why don't we try the ?"

"Our standard is high, and the oil and gas pressure in Aqijiu Oilfield is higher. In case of another blowout, we won't be able to eat. Don't you know that the last time the whole derrick flew to the sky? If the explosion-proof level of the drilling platform hadn't reached level 2, maybe the drilling platform would have burned. I'll let you go, and the later inspection will not pass. The supervisor is also an employee of Dahua Industry. Although he is on the drilling platform with the drilling team, he and the drilling team belong to two units, which is equivalent to the existence of Party A. He supervises Party B on a full-time basis and requires the other party to complete the work in accordance with the prescribed steps.

The current Sertan oil field, or several oil fields opened up by Dahua Industry for the Russians, has a large number of drilling teams from the Petroleum Corporation for Dahua Industry to be the Party B, that is, the pure construction party. There were also many construction teams of Party B in Aqijiu Oilfield, but only by the order of Su City, all of them were changed to Dahua's own team.

However, the construction personnel have changed, but the institutional structure has not changed substantially. Not only that, due to Su Cheng's close attention, the Dahua employees in the whole A-A region are very careful. The rules and regulations of safe production are hanging in the air like the golden rule, and several people who dare to touch it, even if they have not been It is necessary to be demoted, deported and repatriated for retraining.

Lu Xiangfei finally climbed up the "special contribution list". Naturally, he didn't want to be kicked down because of the violation of discipline. He gritted his teeth and said, "The standard of test pressure is high, and there must be valves that can't stand it. We don't have enough materials we store now. Now we have to let the

"No problem." The supervisor was also very clear about his responsibilities and agreed.

"I can't sleep now." Lu Xiangfei sighed, went back to give the order, and he did it first.

The drillers howled, and after it didn't work, they had to follow Lu Xiangfei to start debugging.

The ring sealer is used on the drilling platform 505. The rubber core is a big weakness, which is operated by means. If it is used well, it can also reach a good level.

As the captain, Lu Xiangfei is naturally the best in technology. He went to the battle in person, checking and debugging more than 200 gates in order. It was originally expected to start drilling in the afternoon, but naturally it didn't work. In fact, when it was time for dinner, it was only the completion of the second round of inspection.

"Can you try it?" The supervisor was also anxious. It was his first job to ask the whole drilling platform to follow the regulations, but time is also very important. Every big Chinese knows that the company has invested a lot in Azerbaijan, and it costs a lot of money. If it hadn't been for the safety regulations, he also hoped to start drilling as soon as possible.

Lu Xiangfei looked at it again, wiped his sweat, straightened up and said, "Try it, just try, prepare first."

There is no need for him to say it alone. The blocker, clear water and sealant ring were in place in an instant, and the high-pressure area was also surrounded by the warning belt. The drill and the deputy drill took the mud pump and the water hose belt, looking like a pillow.

Lu Xiangfei and Si Dian put a cleaning head on the weighted drill pipe. After cleaning the wellhead, go down to the well, and connect the upper end with a blocker coated with butter...

When everything was ready to stop, Lu Xiangfei shouted directly in a hoarse voice, "Cut the valve, 10 pressures first."

10 pressure is 10 atmospheres, which is about 1 MPa, which is a relatively small wellhead pressure.

The well sealer 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 hit 30 pressures."

As the drill did, the engineer shouted with his pocket watch, "3 MPa stabilizes the pressure for 10 minutes and start the timing."

Lu Xiangfei sat on the raised edges with a relaxed expression.

The well sealer they are using now is produced by Dahua Industry, which is not as good as the imported goods of Setan Oilfield, but it is still much better than domestic products. This is also determined by different working environments. Several domestic companies rarely go abroad to do projects. The pressure of their own oil wells in China is small, and almost the well sealer can do it. Su Cheng is trying to occupy a few large oil fields, and has high requirements for all kinds of self-produced oil well equipment.

Historically, China National Petroleum Corporation began to encounter problems such as well sealers in the exploitation of Sudanese crude oil. However, before that, they also often used imported goods.

3 MPa is extremely easy for any kind of well sealer.

After 10 minutes of stabilizing the pressure, the drill asked Lu Xiangfei for instructions, and then slowly increased the pressure of the mud pump to 20 MPa with the deputy drill.

Lu Xiangfei just stood up at this time.

The supervisor also craned his neck and pinched his watch to check the time.

Just three minutes after the hour hand, the mud began to sip under the gate.

"Is it okay?" The supervisor turned his head and asked Lu Xiangfei. This level is not too bad, and it is still on the verge of being used.

Lu Xiangfei scratched his head: "Look again."

At the end of the 10-minute voltage stabilization test, the gate did not burst, but the glue core was closed and could not go back.

Lu Xiangfei expected, "The cushion doesn't work. This well sealer needs to reach 200 pressures, and all of them have to be replaced with new ones to have hope."

"I'm going to urge the supply ship." The supervisor called without saying a word.

At 12 a.m., Dahua's own night ship shipped the needed supplies. At this time, even if they do not pursue confidentiality, the Azerbaijanis in Baku will not sail.

The supervisor went to check the materials on behalf of Party A, and Lu Xiangfei had removed all 48 one-inch three large screws. Not only the drilling team, but also workers and engineers from other departments have also come to help, or adjust the derrick, or help change the mat and oil it.

Try again. The ring well sealer persisted for 5 minutes under 200 pressures, and the rubber core broke down again.

"Change it again." Lu Xiangfei looked like an old scalper. Only when the well sealer reaches the best working state can he withstand 200 atmospheres.

48 large screws were removed again, all the mats were replaced, buttered again, and then the gate was reinstalled.

Several workers were busy on the ground for more than an hour before adjusting the huge screws in place. Lu Xiangfei checked one by one to achieve the maximum effect. The screws are too tight and too loose. In the most exquisite fine processing workshop, there are rules on how many circles on the screws. It is decided that some factories take a year and a half to meet the design requirements. The quality rate is to try these detailed things.

The offshore drilling platform does not require special precision, but if the equipment is to reach the best condition, it must require special precision.

On the sea at night, the cold wind does not stop. Even if you wear four or five pieces of clothes, you can't help stamp your feet. It is definitely a hard job to load and unload huge screws on the cold steel surface, not to mention that the current steel surface has been covered with mud.

It is bitter, tiring and dirty, and it is basically declared that this work is unacceptable.

The supervisor looked at the shivering of nearly 40-year-old Lu Xiangfei, took off his gloves and touched the screws to twist them. He was really sorry. He simply took off his military coat and put it under Lu Xiangfei's legs and said, "If it doesn't work, let's do it tomorrow. Otherwise, let's

"The wellhead should also be adjusted. It's not much better. As long as this well can produce oil, I'm happy to do it for another two nights." Lu Xiangfei asked someone to take another military coat to put it on the supervisor and continued to stuff his head.

In just a few minutes, the supervisor's frozen lips turned blue. He was embarrassed to put on his clothes and shivered, "Su Dong said that the oil field under our feet is one of the best oil fields in the world. What we want is the oil well with the largest output. Next time, it must be crude oil under the well sealer."

"200 pressures, if the crude oil can still come out..." Lu Xiangfei suddenly smiled twice and said, "I'll admit it."

"I admit it too! The most promising opportunity to see a 10,000-ton oil well in my life is now. The supervisor wrapped in his coat suddenly sighed.

The average 10,000-ton well has less than 200 atmospheres, so the high pressure of the 200-pressure well sealer cannot be stuck must be a high-yielding oil well.

Although the oilfields occupied by Dahua are good, there are only so many high-yield oil wells in the world. If a company can meet two, it will be celebrated and decomposed into drilling teams. I really can't tell whose luck it is.

Supervise a sentence, but it makes everyone feel something, and the action is unnaturally fast.

The third test still failed.

The fourth test still failed.

Each time, all parts must be removed and gaskets and lubricants should be reinstalled.

Repetitive and boring work makes people dizzy and almost vomiting.

Lu Xiangfei frowned and persisted.

The rest of the drilling team gradually lost their mood to complain and continued to work with the captain.

The work on the platform is originally dirty, tired and hard. People who can't stand this pressure will definitely not be able to stay.

It took a total of 30 hours to test the pressure before it was successful.

At this moment, the faces of the people on the whole drilling platform are wooden. On the one hand, the cold wind blows, and on the other hand, it stays up late.

Lu Xiangfei signed the documents given by the supervisor, so he went back to sleep. People from other departments tried their best to help clean up. The next work is still the drilling team. They can't sleep well.

The next day, a fragrance woke up Lu Xiangfei.

"What is it?" He looked down from the upper bunk, and the place on the drilling platform was expensive, which was basically the same dormitory as the school.

In the lower berth was Huang Donglei, an engineer. While digging the lunch in the plate, this amazing-minded guy said, "Su Dong is here. He has enough rice, half of the meat and half of the rice."

"Is Su Dong here?" Lu Xiangfei repeated it.

Huang Donglei couldn't make a clear point at all. "Um," he said crookedly, "You haven't eaten breakfast or lunch, have you? Hurry up and get the soup in the canteen. If it's later, the wolves will have finished it.

"Why don't you eat in the canteen?"

"There are several executives in the headquarters. I ate two servings. I was a little embarrassed. I said that I would make a basin for the drilling captain of the dormitory. Su Dong heard it and asked about you. Look, the cook is cooking for you, and there is more meat than others. Oh, if you go to the canteen and are asked, just say that I overturned the rice bowl on the way. Huang Donglei said while eating, and the speed of both projects was extremely fast.

Lu Xiangfei jumped out of bed, blocked Huang Donglei's wave of chopsticks, and said, "Do you think Su Dong asked me?"

"Yes, he said that when you wake up, he will let you see him. Otherwise, do you think the cook is willing to let me bring it back? Give me so much meat? Look, it's all small ribs, which is probably hidden by that guy.

"Su Dong asked me to see him as soon as I woke up?" Lu Xiangfei was stunned for a moment and said angrily, "Why didn't you say it earlier?"

"Didn't I say that?"

"I'm going now." Lu Xiangfei put on his trousers, picked up his clothes, and ran out.

Beside him, Huang Donglei said slowly, "Do you know where Su Dong is?"

Lu Xiangfei, who had run out of the speed, braked abruptly. When he came back, he stared at Huang Donglei and said, "Isn't it in the canteen? Do you know where it is?

"Oh, you know." Huang Donglei blinked and bowed his head to plan the rice.

"What do I know?"

"In the canteen, I thought you didn't know." Huang Donglei looked like a fool.

Lu Xiang was so crazy that he grabbed his chopsticks angrily, ran in two steps, and threw them directly into the sea.

Huang Donglei got up calmly, opened the drawer, took out a pair of new chopsticks, and said silently, "It's bamboo chopsticks, or it will cause pollution."

Lu Xiangfei ran to the canteen as fast as he could. Sure enough, he saw Su Cheng and his party. The most conspicuous one was Qin Shiwei, who was stronger than the iron pillar.

"President Qin of the Drilling and Oil Extraction Research Institute? What is he doing here?" When Lu Xiangfei saw him, he first had a wave of doubts, and then there was ecstasy.

Qin Shiwei is famous for his regard of time as life, and he never does things like socializing or accompanying.

Strong body, superb technical level and the attention of Su Cheng make Qin Shiwei as special as an active boss in the eyes of grassroots workers - where he is, it usually means some kind of activity.

And in the current drilling platform, the only activity is oil production.

"Do you have a new plan?" Lu Xiangfei didn't sleep very awake. When he came to Su City, the ghost said a word.

Su Cheng smiled and took the initiative to shake hands with him and said, "Captain Lu, I heard that you have worked for two days and one night in a row. Are you tired?"

"I'm not tired. What's so tired? That's what we do." Lu Xiangfei is a little proud. This is the boss asking us for warmth.

Qin Shiwei was not ready to give them time to greet them. He knocked on the table and said, "We have been checking the earthquake data recently. The edge exploration well on No. 507 is in good condition. According to the latest feedback, I have made a new formation map. You can refer to it when you drill wells."

The stratigraphic in the mid-1990s was quite simple, but the basic functions were still complete, and Lu Xiangfei could also understand it. He tilted his head and thought for a while and said, "So, are we connected with 503?"

"Yes, and if it's lower on our side, the output may be higher."

"Then I understand."

"As long as you understand, let's go." Qin Shiwei got up and began to collect the drawings.

Lu Xiangfei didn't understand again and asked, "Where are you going?"

"Open the drill!" Qin Shiwei looked even more confused.

"Ah...ah!" Lu Xiangfei woke up like a dream and quickly followed him, thinking: These engineers from the Petroleum University are all stunned, one by one is unreliable.

Su Cheng nodded around with a smile and followed Shi Shiran.

Soon, the rig rumbled.

Since Dahua Industry started drilling in November last year, it has drilled three rounds, with a total number of more than 10, but it is not very lucky, and most of them are dry wells. However, with so many oil wells as the bottom, the geological situation below has been very clear. Qin Shiwei's drawings are still predicted at present, but once confirmed, it is a standard distribution map of underground crude oil.

In fact, the situation encountered by Dahua Industry in Aqijiu Oilfield is the most common situation in the oil industry. To be more precise, more than two of the 10 oil wells in the early stage have seen oil, which is quite good.

Only in this proportion can the oil company stick to it. Otherwise, even drilling five dry wells will not see a little oil star, and no matter how strong the oil company is, it can't stand it. And if there are more drills, the situation below is understood, and the probability of getting out of the dry well is small.

What Lu Xiangfei is doing now is more like a pure oil production well than an exploration well.

Under his command, the drilling team accelerated the pace of the drawing.

On the afternoon of June 16, the drill bit arrived at the designated position.

"Bottom casing!"

"Test the oil!"

A series of actions, Lu Xiangfei's drilling team is extremely proficient.

Qin Shiwei stood in the position of supervisor and stared at the following movements. What he wants is a successful oil test, which can show the accuracy of the crude oil distribution map.

Su Cheng was also in a bad mood. He said with a poker face, "The situation looks good. Don't worry."

"What do I have to worry about?" Qin Shiwei covered up and said, "If you don't succeed this time, if you want me to say it, you have to take the road of exploring the well..."

"Don't say anything unlucky." Su Cheng interrupted him.

Qin Shiwei said, "Do you still believe this?"

As soon as he finished speaking, the drilling platform was a shock.

The derrick also made a "cooing" sound, as if there was a hiccup at the bottom of the sea.

Qin Shiwei was stunned for a moment, and his expression instantly changed from giggle to cute, like a bear whose face was swollen by a bee.

"The oil is out..."

Su Cheng muttered, and his voice was completely covered by the noise in his ear, and his mood was inexplicably calm.

It should be said that he didn't feel calm before until now.

The exploitation of Aqijiu oilfield really consumes him too much energy and too much resources of the group. It is reasonable to produce oil, but the dry wells that are not so reasonable have caused too much pressure.

Not only Sucheng has been under great pressure, but the whole Dahua industry has been under great pressure.

Even, these people who don't know about the Aqijiu oilfield are under greater pressure.

After a short period of dementia, Qin Shiwei rushed up to check. Yang Ming, Li Shirong and others did not have the usual calmness. They looked at the front at a loss, and they were all happy and stupid.

"We need to drill a second oil well immediately, and a third one, here and here!" I don't know when Qin Shiwei ran back. He pulled away the drawing with stains and pointed to the two key points on the forks.

Su Cheng seemed to be awakened. He nodded twice, and then grabbed Li Shirong. In the endless noise, he shouted in a loud voice, "Confidential, oil well secret!"
