Relieve Dependence on External Energy Resources Linxing Gas Field is located in Lvliang City, Shanxi Province, on the eastern edge of Ordos Basin. The structural activities in this area are complex, and it is generally considered that it is difficult to form a large gas field. Through technical research, after CNOOC in China obtained the first high-yield gas well, a number of high-yield wells were discovered one after another, which opened the exploration of Linxing gas field. By the end of 2020, CNOOC China will be in the gas-bearing area of nearly 728 square kilometers in the Upper Paleozoic Permian, and the proven geological reserves of natural gas will reach 1000 billion cubic meters.
Deputy General Manager of China Offshore Oil Corporation said: Like coalbed methane and shale gas, lipophilic tight gas belongs to unconventional natural gas.
At present, 526 wells have been drilled in this gas field. In 2020, the daily output of natural gas will exceed 5 million cubic meters, and the cumulative supply of natural gas has been 654.38+83.6 million cubic meters since it was put into production.
According to the plan, CNOOC China strives to build Linxing Gas Field into a gas field with an annual production capacity of 3.3 billion cubic meters and an annual output of 2.7 billion cubic meters in the next three years. The natural gas from Linxing gas field is expected to be transported to xiong'an new area in July this year.
The following report from CNOOC
China CNOOC announced that the proven geological reserves of Shanxi Linxing gas field have exceeded 1.0 1 billion cubic meters, and China CNOOC has successfully discovered onshore 1000 billion cubic meters gas field.
At present, the gas field is further accelerating exploration and development, which will greatly enhance the supply capacity of clean energy in North China and provide green and clean energy guarantee for the implementation of the strategy of developing the western region in the new period and the construction of xiong'an new area.
Linxing Gas Field is located in Lvliang City, Shanxi Province, on the eastern edge of Ordos Basin.
The tectonic activities in this area are complex, and it is generally considered that natural gas is seriously dissipated and it is difficult to form an atmospheric field.
Through technical research, China Offshore Oil Corporation obtained the first high-yield gas well at the end of 20 13, and found a number of high-yield wells one after another, which started the exploration of Linxing gas field.
By the end of 2020, CNOOC China will be in the gas-bearing area of nearly 728 square kilometers in the Upper Paleozoic Permian, and the proven geological reserves of natural gas will reach 1000 billion cubic meters.
According to Zhu Guanghui, deputy general manager of China CNOOC Zhonglian Company, 526 wells have been drilled, 1 1 station has been built, and 483 kilometers of pipelines have been laid. In 2020, the daily output of natural gas will exceed 5 million cubic meters, and the cumulative supply of natural gas has been 654.38+83.6 million cubic meters since it was put into production. Among them, the supply of gas for people's livelihood and clean heating with high quality and good price to the old revolutionary base areas totaled 2,665.438 billion cubic meters, which effectively promoted the economic and social development and air quality improvement in the old revolutionary base areas.
According to the plan, CNOOC China strives to build Linxing Gas Field into a gas field with an annual production capacity of 3.3 billion cubic meters and an annual output of 2.7 billion cubic meters in the next three years.
While helping local economic and social development, the natural gas from Linxing Gas Field is expected to be directly transported to xiong'an new area in July this year to build xiong'an new area? Green and low-carbon city? Provide clean energy security.
In recent years, China Offshore Oil Corporation has carried out? Four revolutions and one cooperation? In the new strategy of energy security, domestic offshore oil and gas production exceeded 65 million tons for the first time in 2020, and crude oil production increased by 2.4 million tons year-on-year, accounting for more than 80% of the country.
While increasing domestic offshore oil and gas exploration and development, we will actively develop onshore unconventional oil and gas business. In 2020, the output of onshore unconventional natural gas will reach 2.27 billion cubic meters.
Linfeng Simi gas field, like coalbed methane and shale gas, belongs to unconventional natural gas. Because its genesis and reservoir-forming mechanism are different from conventional natural gas, it is difficult to develop and needs some special technologies to exploit.
For example, coalbed methane needs drainage technology, shale gas needs large-scale hydraulic fracturing technology, and Linfeng Simi gas field is currently exploited by fracturing stimulation technology. The scientific research, exploration, development and production personnel of Zhonglian Company innovatively put forward the concept of dense gas? Structure, microfacies, physical properties, cracks? Through multidisciplinary joint research, many technical problems such as thin reservoir, large lateral change, low reservoir resistivity and difficult identification have been solved, and fruitful and innovative research results have been achieved, which is helpful to realize the breakthrough of tight gas exploration in Linxing gas field.
During the construction process, Linxing Gas Field successfully explored the integration mode of exploration and development, found a high-quality dessert area to deploy comprehensive evaluation wells, and quickly implemented the evaluation of reserves and productivity. Through the integration idea of rolling while exploring and transferring high-yield exploration wells to development wells in advance, the productivity construction period was shortened from 6-8 years to 3-4 years, which realized the rapid conversion from reserves to production and accelerated the completion and commissioning of the gas field.
China CNOOC chairman said? Fourteen or five? During this period, China CNOOC will accelerate the development of onshore unconventional natural gas business, effectively boost the company's natural gas output to 35%, and build a diversified clean energy supply system to help China fully realize with more powerful and practical measures? Peak carbon dioxide emissions, carbon neutrality? Target.
