The 14th Five-Year Plan is a period of great development of China's natural gas industry

For the development of shale gas, Dai Jinxing also pointed out specific directions. He said that the shale gas found so far in China is sapropelic shale gas, no coal measure shale gas has been found, and the study of coal measure shale gas is of great significance. He pointed out that the coal-measure shale gas in Ordos Basin has good prospects and potential.

Technological innovation is essential

In fact, China has made great progress in shale gas exploration and development in recent years. Since the first shale gas survey well in China discovered shale gas in Sichuan in 2008, shale gas production began in 2012, and shale gas output exceeded 20 billion cubic meters in 2020, forming shale gas production bases such as Fuling, Weiyuan and Changning. The shale gas industry has developed steadily.

However, due to the constraints of formation, surface conditions, and technical service market maturity, China's shale gas exploitation is also facing many challenges.

Experts at the meeting pointed out that because the temperature of deep shale is as high as 140℃ and the difference of ground stress is greater than 20MPa, the existing technology and equipment are difficult to adapt to the temperature and pressure conditions, and some core key tools rely on imports; In addition, the full cost of shale gas is as high as 1000 yuan/one thousand thousand, 20% -30% higher than conventional natural gas, the initial production of gas Wells is generally 80,000 to 100,000 square meters/day, the decline rate is fast, the need to continue to drill Wells to maintain stable production, workload and investment pressure.

In this regard, the shale gas "14th Five-Year Plan" of the Exploration Institute pointed out that the production oriented, the technical ability and cost as the main evaluation indicators, the optimal construction team; Strengthen research on key core technologies, actively promote the construction of national shale gas science and technology major projects and deep development demonstration projects, and use technological innovation to drive high-quality development of shale gas business; Optimize resource allocation and production organization, plus
