The impact of the global energy pattern of shale gas revolution in China to speed up the industrialization into commercial production stage, Chinese become shale gas producing countries and the United States, Canada dingzuerli.
Geological survey of land and resources division director Yu Haifeng, at a press conference here said, after the exploration practice of development for many years, shale gas exploration and development in China has made a major breakthrough. The marine strata in the Sichuan basin and its surrounding areas have accumulated proven reserves of 764 billion 300 million cubic meters of shale gas. Among them, the Chongqing Fuling shale gas field accumulated proven geological reserves of 600 billion 800 million cubic meters, becoming the largest shale gas field outside North America, is expected to build an adult production capacity of 10 billion cubic meters at the end of this year. Sichuan Weiyuan Changning shale gas accumulated proved geological reserves of 163 billion 500 million cubic meters.
Shale gas utilization is related to national energy security and has a significant impact on future development. The last century since 80s originated in the North American shale gas revolution, not only changed the North American energy supply and consumption pattern, because the technology is mature, the United States to achieve the basic self-sufficiency in energy and by reducing the price of natural gas, effectively inhibit oil price, promote American manufacturing regression. As the largest energy consuming country and an industrial big country outside the US, it is necessary for us to develop shale reserves with abundant reserves. Since the State Council will be officially listed as independent minerals of shale gas, geological workers in China through 30 years of hard research, America traveled a few years. In 2016, China's shale gas production reached 7 billion 882 million cubic meters, second only to the United States and Canada, ranking third in the world.
Under the joint efforts of all parties, through technology introduction, digestion and absorption of technology, China has mastered shale gas geophysical, drilling and fracturing technology, with 3500 meters in shallow (part of the area has reached 4000 meters) horizontal drilling and fracturing, the initial formation of suitable geological conditions of shale gas in China the exploration and development of technology system.
It is reported that, by increasing shale oil and gas survey and evaluation efforts, China's southern shale gas survey made a major breakthrough, is expected to build two shale gas resources base. The upper reaches of the Yangtze River in Guizhou Zunyi page 1 well got more than 100 thousand cubic meters / day stable industrial gas production; the middle reaches of the Yangtze River in Hubei of Yichang province to page 1 wells have access to high-yield shale gas AOF 123 thousand and 800 / day in the Cambrian, and so far the world's oldest discoveries of shale gas in Sinian; 1 wells in lower reaches of Anhui the port of Xuancheng at the same time make important discoveries of shale oil, coal gas, tight gas and shale gas. Shale gas exploration breakthrough from the upper reaches of the Yangtze River economic belt to the middle and lower reaches of the expansion, is expected in Guizhou, Zunyi, Hubei, Yichang shale gas business development.
Shale gas is a clean and efficient energy source. The United States began to exploit shale gas from the 80s of last century. At the beginning of this century, the technology matured, completed a shale gas revolution, and realized the basic self-sufficiency of energy. In 2011, the State Council approved the shale gas for China's 172nd kinds of minerals, the Ministry of land and resources will be managed by independent mineral gas, shale gas support and utilization of subsidies followed by launch. And strengthening the work related to ecological environment assessment and protection has become a top priority.
