Abstract

According to relevant estimation, the recoverable reserve of shale gas in China is up to 20 to 30 trillion m3. Although shale gas reserves evaluation is still in the early stage, it quite sure that China is one of the countries who are rich in shale gas resources. If developed subject to current gas annual production, it can be developed for more than 200 years. At present, many companies home and aboard focus on shale gas and compete it in China, and it is expected that shale gas will be the substitution of conventional energy resource in China. Thus the exploration and development of shale gas will bring great effect not only on China but also on the world. However, due to the tightness of shale gas reservoir and its permeability is as low as 10-9 Darcy scale, if especial stimulation treatments are not taken, it would be very difficult to achieve the goals of commercial development. For the moment, America is the only country in the world that is successful in commercial development of shale gas and its technology and commercial operating mode has been very mature too. CNOOC has invested more than 1 billion US dollar to buy 33.3 % interest of Eagle Ford, where its reserves reach about 600 billion m3, and where its development prospect is valuable. In order to get a comprehensive acknowledgement on the development technology, the author, as a leader, accompanied by a professional team has had a tour observation to Eagle Ford in America and has got a further understanding on key technologies in horizontal drilling and multi-stages fracturing etc. Meanwhile the author also has analyzed the relevant supporting policy framed by USA government, which will be important and valuable for shale gas exploration and development in China.
