Oil and gas development is cleaner and low -carbon. Oil uses photovoltaic power generation. Traditional fossil energy and new energy are perfectly coupling in the vast oil field of Xinjiang.

Under the leadership of scientific and technological innovation, a profound change in the field of oil and gas is staged in Xinjiang.

Water, fire, and air -to -air together to increase oil

In August, Uerhe, the hot sun burned the ground. Among the turbulent waves, the "Iron Warriors" wearing blue armor stood toughly in Fengcheng Oilfield.

The "steel warrior" standing here is endless, and thick oil is continuously drawn from the ground. These "steel warriors" use SAGD technology (steam -assisted gravity oil leakage technology), which uses crude oil from horizontal wells.

Why do I use steam? Because there is thick oil here, thick like honey and asphalt. The use of steam is to simmer thick oil to make it liquid and easy to minimize.

At first, Xinjiang Oilfield introduced SAGD technology from Canada, and the harvest rate increased by 20%-25%compared with traditional steam throughput. After more than 10 years of development, SAGD technology has been integrated and innovated in Xinjiang Oilfield, forming China's thick oil mining samples, and has begun to output technology abroad.

In order to further improve the harvest rate, Xinjiang oil fields are currently experimenting with fire drive technology, that is, through underground ignition methods, it can be used to increase the thick oil after underground. The use of this technology can be increased to 60%.

The Mahu Oilfield and Jimusar Rock Oil are two 1 billion tons of oil fields discovered during the "Thirteenth Five -Year Plan" period. At the beginning, Xinjiang Oilfield injected water to Naizhong and horizontal wells, but the penetration rate was extremely low after the water injection, and it could not benefit. Since then, Xinjiang Oilfield has introduced horizontal fracture techniques from abroad, but it is used to "not accept the soil and water" in the Mahu Oilfield.

"Mahu Oilfield Cjain is very thick, the reservoir is not developed naturally, and the horizontal two -way stress is particularly large. After quoting the horizontal well -volume fracture technology, it is difficult to press the sewing net at first. Relatively dense cuts to form more artificial gaps. "Said Qin Jianhua, a member of the Party Committee and General Geologicalist of Xinjiang Oilfield Company, said.

Today, the Mahu Oilfield has found a new model of unique and unique oil and gas effective development models, forming more than 10 key technological achievements, and building a demonstration zone of the dense oil development of the Junggar Basin. Essence

With scientific and technological innovation -driven development, the harvest rate of the Mahu Oilfield has increased from 12%to 18%; the harvesting of Jimosar Rock oil has increased from 6%to 13%.

Drilling is close to 10,000 meters

Challenging the deep and super deep, at the moment, the designed oblique deep well with a depth of 9,186 meters of the Tarim oil field -full deep well, and the gongs are drilling in secret.

The full 10 well is the deepest well in Asian land design. In recent years, the Tarim Oilfield has continued to challenge the deep limit. It has successfully drilled 41 deep wells over 8000 meters, and has built my country's largest ultra -deep oil gas production base, leading and promoting my country's ultra -deep oil and gas development to the forefront of the world.

Diamond diamonds need to be used for porcelain. Drilling the depth of "underground Everest", which needs to meet the ultra -deep well load limit rig.

The reporter learned from the China Petroleum Group Western Drilling Engineering Co., Ltd. that the company has more than 400 rigs, 10 9000 meters rigs, 11000 meters, 11, 7000 meters and 93. In order to seize the deep ultra -deep drilling market, the company is currently cooperating with the Baoji Petroleum Machinery Co., Ltd. to study the 15,000 -meter deep drilling machine with the ability to explore 10,000 meters, and put it into the Tarim Basin to test it to help Xinjiang's oil and gas resources development goes deeper.

Design and research and development of ultra -deep drilling machines, the core technology is to solve the ability of high temperature and high pressure in the drill bit. At present, when the 8000 -meter -deep drill, the temperature at the bottom of the well has exceeded 200 degrees Celsius, and the underground pressure has exceeded 140 MPa. Such a large pressure, like a elephant stepped on a ant, the ants instantly shattered the bones.

The 15,000 -meter -deep rig requires the drill head to resist 230 degrees Celsius high temperature and 170 mega -Paka pressure.

In the scene where the oil was looking for oil, it also ignited the hopes of "Tuha" in Tuha oil field to find the fire of "Tuha". After the oil and gas industry experts "diagnosed the pulse", the Tuha oil field decided to explore into the deep exploration. "In the past, Tuha Oilfield drilled more than 5000 meters. Now most of the exploration objects are below 5000 meters, and the deepest drilling has been explored 7150 meters. We hope to find another Tuha oil field below 5000 meters." China Petroleum Zhao Xuchen, manager of Tuha Oilfield Company Tuha Oil and Gas Exploration Project, said.

Coupling of traditional energy and new energy

Perhaps, after three or five years, the oil area on the Gobi Beach not only has a "hoe machine", but also can see the blue photovoltaic board.

The reporter learned from China Petroleum Xinjiang Oilfield Company that in late July, the company has implemented "new energy+" energy supply to the edge of the well, using "photovoltaic energy supply+24 -hour energy storage" power supply method, and combined with the single -well screw pump transfer pump. Activated high -quality production capacity of electrical borderless wells. Extending the industrial chain, China Petroleum Caramay Petrochemical Co., Ltd. has built 150,000 tons/year white oil hydrogenation device. Correspondent Jin Ling

Clarma is rich in light and heat resources. When the sun is sufficient, the power generation of the photovoltaic institution is in addition to meeting the production of oil wells, and the remaining power is stored in the energy storage cabinet. When the sun is insufficient, the power of the photovoltaic institution cannot meet the needs of the oil well.

The implementation of the "double carbon" goal, and the oil fields that mining traditional fossil energy have begun to transform. In recent years, various oilfield companies have successively established a new energy business department to explore traditional energy and new energy coupling paths to achieve green and low -carbon development of oil fields. The Tarim Oilfield proposed this year that it can catch the construction of oil and gas in one hand, grasp the rapid development of new energy, and accelerate the construction of green low -carbon transformation and the construction of new energy bases for "Sha Ge". Two months ago, the first zero -carbon desert highway was built here; now, the 200,000 kilowatt photovoltaic power generation projects in the end of the county have also started construction.

CCUS (carbon capture, use and sealed) is a breakthrough in the low -carbon transformation of oil and gas companies. At present, the major oil fields in Xinjiang are conducting carbon dioxide -driven pilot tests. Among them, Xinjiang Oilfield will pull carbon dioxide capture from China Petroleum Caramay Petrochemical Co., Ltd. (hereinafter referred to as Kerrite) to inject the underground of the oil well. While increasing the harvesting rate, the carbon dioxide is permanently buried to the ground.

As of the end of 2021, Xinjiang Oilfield has tested more than 1,300 wells, with a cumulative injection of 350,000 tons of carbon dioxide and an oil increase of 130,000 tons.

Xinjiang Oilfield proposes a long -distance plan. It is expected that by 2035, 10 million tons of carbon dioxide will be injected into the annual carbon dioxide. "Which plants are more suitable for carbon dioxide drives? How to use carbon dioxide driving how to promote growth and avoid weaknesses, now we are stepping up technical research." Qin Jianhua said.

Extension chain supplement chain promotion cluster development

Utilizing the thick oil of Xinjiang Oilfield, China Petroleum Caramay Petrochemical Co., Ltd. has led scientific and technological innovation to step out a characteristic development of "eating coarse grains and boutique".

The ultra -high -voltage DC transmission voltage produced by Kewey Petrochemical has been successfully applied to the world's highest voltage level -Changji Yigu Spring ± 1100 kV high -voltage DC transmission project; BS bright oil, freezing oil, internal combustion engine oil basic oil, rubber oil, etc. Product quality has reached international and domestic leading levels, and occupied important share in the domestic market.

In southern Xinjiang, the Petroleum Petrochemical Industrial Park (hereinafter referred to as the Shangku Industrial Park) of Tarim Oilfield, China Petroleum Dugga Petrochemical Company, and Korla Shangku High -tech Industrial Development Zone (hereinafter referred to as Shangku Industrial Park) is extending the industrial chain: Tarim Oilfield uses natural gas to produce ethylene, B After the alkane was sent to the PetroChina Petrochemical Tarim Petrochemical Branch of PetroChina, which is located in the Shangku Industrial Park, ethylene was produced.

What is ethylene? This compound composed of 2 carbon atoms and 4 hydrogen atoms is actually closely related to everyone's life. It is known as the "Mother of the Petrochemical Industry". Taking ethylene as the raw material, it can produce various plastic, pipes, chemical fiber, etc., extend the downstream industrial chain, and can develop hundreds of products.

Relying on ethylene resources, Shangku Industrial Park is planning to build an industrial cluster to realize the transformation and upgrading of "one cotton", "one drop of oil", "one side" to "one cloth" and "one piece of clothing" to promote the high -end high -end downstream of the textile industry Weaving extension.
