NewsSince 2008, great breakthroughs have been made in the major national science and technology projects for the development of large oil and gas fields and coal-bed methane. Since the implementation of the project, a number of key technologies concerning oil and gas fields and coalbed methane production have been made.
Petroleum and natural gas are excellent energy sources in fossil energy resources, and coalbed methane is a new type of energy source. Accelerating the exploration and development of China's oil and gas resources and the development of the oil and gas industry are of great significance to the protection of China's energy security, the optimization of energy structure and the promotion of economic growth.
In the field of unconventional oil and gas exploration, China has realized the industrialization of coalbed methane and coordinated development of gas extraction and coal mining in the coal mining area, which has led to the development of new industries in shale gas industry. The formation of low cost technology of coalbed gas exploration and development, Baode, built 2 CBM industry base, 2016 ground production 4 billion 500 million square; coal mining area coal gas coordinated development to protect the safe production of coal mine, mining underground pumping 12 billion 800 million party formed in 2016; the key technology of the development of shale gas, built in Fuling, Changning - Weiyuan and other industries demonstration zones, shale gas production in 2016 7 billion 800 million.
For oil and gas extraction, geological conditions determine the difficulty of exploration and development. The exploitation of oil and gas Chinese faced with very complex geological conditions, a lot of low permeability oil and gas resources, deep exploration and exploitation, utilization is difficult, especially when compared to the Middle East, North America, Chinese oil and gas development "congenital disadvantage" is more obvious, directly pushed up domestic oil and gas prices, the unfavorable situation with the international market price upside down.
Take the Tarim Basin, Kuche natural gas, for example, the average well is buried 2000 meters to 3000 meters, and the well is buried 6000 meters to 8000 meters deep. First through the development of oil and gas field seismic exploration technology, the underground face carved out, this technology depth is more difficult for drilling, drilling 8000 meters deep in the depth and difficulty of the world's top three ranking certainly." Oil and gas development special technical chief engineer Jia Chengzao said, "we rely on technology to find out their underground features, determine drilling targets, rely on their own drilling technology, successfully found 5 large gas fields in Kuche deep billion, trillion scale atmospheric zone formation. This is through the national special research, gathered the national oil industry parties to achieve the strength".
China not only in the deep gas accumulation theory and supporting technology has made significant progress, the formation of key technologies and forming theory of complex mountainous seismic, ultra deep and high pressure drilling exploration deep into the foreland, but also the innovation and development of theory of reservoir and reservoir prediction technique of ancient marine carbonate oil and gas, the formation of large gas field in Anyue China the oldest field surfaced, become a major discovery of natural gas on the history of the development of China.
