[Chinese Dream · Big Power Artisan Artisan] Fang Zhigang: Every drop of crude oil is the crystallization of technology

Editor's note: The theme publicity activities of the "Chinese Dream · Great Power Artisan" were jointly carried out by the National Internet Information Office and the National Federation of Trade Unions. It aims to vigorously promote the spirit of model workers, the spirit of labor, craftsmanship, and create a glorious social style and the dedication of excellence. The atmosphere, give full play to the role of advanced model figures, and encourage more workers, especially young people to take skills to achieve talents and serve the country.

China Youth Network, Beijing, September 29 (Reporter Mu Haozhang Intern reporter Wu Boyang Correspondent Hasyti Casmu Double Line) Petroleum is the most important raw material for modern industrial society. Everyone's clothing, food, food, housing, and transportation is closely related to oil and natural gas.

For example: a bottle of mineral water placed on the table, this bottle of water has been discovered by the water source, mining, purification, bottling, transportation, etc., and finally placed in front of you, a total of one -third of oil is required. If it is fruit juice, the oil consumption will be as much as half a bottle.

Before graduating from college, like many young people who had not been to the oil field, Fang Zhigang, a first -level engineer of Tuha Oilfield and a technical expert of China Petroleum Gust Center, also thought that a bite of oil wells could be sprayed out, or was pulled out. Apply to all aspects of our lives. However, when he arrived in the Tuha Basin, he knew that the oil was contained in rock sand, and he needed to "wash out" through water and polymers.

Recently, the reporter followed the theme publicity activities of the "Chinese Dream · Big Power Artisan". During the conversation with Fang Zhigang, he learned about the entire process of oil from mining, refining to output, and the sign of "Tuha Qi". Sexual brand technology. "Qi Jian oil is an injecting high -pressure gas into the well from the ground, using the principle of gas expansion, reducing the density of liquid in the well cylinder, and lifting crude oil to the ground." Fang Zhigang is an excellent representative of this technical research. It is the leader of the Qi Ling technical innovation team in recent years.

"What we do is to make the oil well high -yield and stable work"

"Facing the long yellow sand and vast Gobi every day, it is a bit monotonous, but I am used to it." After graduating from college, Fang Zhigang, the northeast guy came to the northwest of the motherland, let him gradually cause this land in Xinjiang to produce the land of Xinjiang. Special feelings, the vast desert has infinite possibilities in his eyes. "If you want to dry oil, you want to choose the place where the oil field is the most. The most promising place in the future is Xinjiang." He said.

At the technical operation site of Naier Oilfield (2397 well) at Kazakhstan, Fang Zhigang entered the radical room to check the air in the air. Interviewee confidence

When he first arrived in Tuha Oilfield, Fang Zhi first came to Tuha Diamond for an internship. But drilling work is different from the scenes in Fang Zhigang's imagination. Fang Zhigang worked from the venue every day, lifted the drilling rod and clear rock crumbs, and all day after day. What impressed me most was that one day a drilling appeared by a nearby, and several drilling teams helped mud. Fang Zhigang and the workers carried heavy crystal stone powder, and a bag poured into the mud pool. A bag of 25 kg, from the afternoon to late at night, when the danger was lifted, everyone was paralyzed in the well field.

This is the first time Fang Zhigang has experienced heavy physical labor. Later, I heard Master said that the overflow was a precursor of blowout, and the heavy crystal powder with mud with mud is used to press the blowout. It is okay to hold the well. If you can't hold the well, it is a blowout accident. At that time, Fang Zhigang appeared in the picture of the Iron Man Wang Jinxi jumped into the mud pool, and he also understood the special meaning behind everyone to carry his shoulders.

After the first Spring Festival in Tuha Oilfield, the company notified Fang Zhigang to report to the Institute of Engineering and Technology. When I arrived at the academy, the first task of Fang Zhigang was designed to design small well -eye expansion sedents. At that time, the drilling process of the opening window of Tuha Oilfield allowed a group of old wells and losing wells to return to work again. However, there is no domestic diameter septor that matches it, and the oil field decides to develop itself.

When designing the rubber tube, the research team encountered difficulties. The size is small, the pressure is not enough, the size is large and the size cannot go down in the well. Adjusting the design repeatedly, it has not solved the problem. "This is like a seesaw. I don't care about it." Fang Zhigang said.

For a few days in the workshop, Fang Zhigang repeatedly thought about it. He found that the most serious deformation of the rubber tube was the two ends, and the main factor that affects the sealing performance.

"Can you change the rubber barrel from a fixed form to activity? This will not only reduce the risk of damage and increase the sealing nature." Fang Zhigang's idea solved the problem after implementation. Master broke his words, the young man had a tendon, and he could do technology and research.

After the production of oil wells for a period of time, the pressure decreases and the output declines, all need to be supplemented by artificial increase in production. In Fang Zhigang's view, among the many artificial lifting oil collection methods, Qi Qi can play its own energy best. Under the condition of gas source, gas picking oil is the most economical and effective way to raise oil in the oilfield. In addition, from the beginning of the production to the final stage of the production of Guanjing's discontinued production, the gas can be used to collect oil throughout the life cycle.

With a lot of energy, the well that is not enough to spray itself can be produced normally, low yield wells can increase yield, and high -yield wells can obtain higher output. Fang Zhigang often said to the team members, "Our work is to make the oil well high -yield stable production, make the oil field develop efficiently, and strive to make the oil field younger."

"The mountain is step by step" step by step "

In 2010, Fang Zhigang took over the 48th breath of the Middle East BBA Oilfield. The biggest problem was the tools of gas.

The BBA oil field crude oil has a "four high", high sulfur, high wax, high carbon dioxide, and high asphalt quality. In particular, the size of the oil well is large and the output is high. The diameter of the Qi Lifting valve work barrel is 168 mm.

"The diameter increased by 41 mm, which seemed to increase only one -third, but the difficulty of the process was the geometric growth, how easy it was!" It was easy to talk about the tool development and manufacturing test of the tool within one year. Essence When they just took over the task in 2010, many people described this as "impossible task."

"The mountain is stepped step by step, and the boat is shook out of one by one." Fang Zhigang said, "If you don't do it, you will never succeed."

Really dry, the problem followed.

The first is anti -hydrogen sulfide. Sulfur is the nemesis of metal. Generally, the metal metal encounters hydrogen sulfide, and the phenomenon of "hydrogen" is generated, and the stress drops sharply, which is easy to break. The upper and lower ends of the air -lifting valve work tube are connected to the oil pipe, which is relatively small in diameter, while the body part is large in diameter, and the overall "two ends are small in the middle". In the past, most of the gas -lifting valve working tube adopted a welding process, a three -stage combination, and two welds. The sulfur has a great impact on welding seams, and it is more difficult to prevent sulfur welding.

Domestic factories have found one family one after another, and they cannot guarantee anti -sulfur welding. "Welding can not be changed to forging!" Forging is not difficult. Solving the problem of shrinkage ratio and pressure resistance alone, I do n’t know how many times I have repeatedly optimized the structure. In the end, it must be selected as an alien workplace similar to ellipse.

Placed the gourd and floated the scoop, and escaped the problem of welding and ushered in forging tests. The alien structure has brought a great increase in the difficulty of forging processing. Finding the top domestic factories in Shenyang is also a pass after more than half a year.

This kind of large and small problems solves dozens of, almost all of them are original solutions. Finally, at the time of awakening the gesture tools. Can I start a few years of gas -lifting tools under the well, can it be started normally? Although every step of anger is precise computing and considerate, it is still original technology under such harsh conditions, and there are still many original technologies. This is not a precedent in China. "It is a dragon or a worm, and you have to see it in the end." Just like greeting the child's birth, Fang Zhigang was nervous and excited in those days. "

At 9 am on July 18, 2017, as the gas injection valve opened, the natural gas sources were continuously injected into the well. The first -level valve is over, and the second -level valve is over. Two days later, the air well entered the normal working state, and the output of the oil well rose steadily until it exceeded 30 % of the early Nissan. Oilfield has won the environmental protection award issued by the local government. This is the first time that the local government's foreign cooperation project has won so much for decades.

"My greatest value is here" here "

In the northern Truca Oilfield (7546) in Kazakhstan, Fang Zhigang (third from left) led the team to deeply design the technical service site and carry out technical services. Interviewee confidence

Oilfield work, serving at home and abroad at home and abroad, Juguo's family life is the norm of Fang Zhigang. Even wives working in the same unit can rarely encounter it.

At the end of 2014, Fang Zhigang hurried back to his hometown in his father who was in the northeast. When I saw my father in the hospital, the condition was very serious and it was not suitable for treatment. My father said, "Child, let's go home." Going home that day, his father died in the middle of the night.

For many years, I have been away from my hometown, and there are only a handful of days with my father. If you want to raise it, you will not wait. Fang Zhigang said that the most regrettable thing was that he could not say that he moved his father and let him come to Xinjiang to live a life.

After the little daughter was born, he was traveling all year round. Occasionally there are vacations, and I can't stay in a few days. When I first saw my father, my little daughter felt strange and cried. Go to bed at night and go straight. A few days later, I finally had a little heat and should leave again.

In 2011, Tuhaqi entered the Middle East market. Fang Zhigang, as the head of the Middle East project in Beijing, was busy like a gyro every day. In July, it was the critical moment of business operation that the two daughters had a high fever at the same time. Three days have passed and still have a high fever. The wife was so anxious that there was no way, and then Fang Zhigang called.

Reporting the leadership, immediately fake holidays, and colleagues arranged in Tuha Oilfield coordinated vehicles to help take care of them. Fang Zhigang finished his hand at hand overnight and ordered a good colleague. Then he hurried back to Xinjiang and rushed to the hospital. At this time, the child's body temperature exceeds 40 degrees Celsius, especially the one -and -half year old daughter is even more serious. After fever, the doctor recommends that he immediately moves to the hospital. Rushed to Urumqi overnight, and the hospital directly arranged into the intensive care unit. Seeing children with oxygen pipes and gastric tubes, this strong Northeast man shed tears.

Fortunately, three days later, the high fever was relieved, and the child could open his eyes, and the couple were a little relieved. A week later, the child turned to the general ward. Fang Zhigang was ready to endure his wife's complaint and scolding, but his wife said nothing. She understands that most of the petroleum families are.

A few years ago, there were also mainland companies that throw olive branches and made high salaries, hoping to seek development together. Fang Zhigang declined. He said, "It was Tuha Qi, which made me, my greatest value is here, and the stage for talent to play is also here."
