中国页岩气研究进展

Research Progress on China's Shale Gas

受美国页岩气成功勘探开发的启示,我国将页岩气的勘探开发提上议程。自2002年起,我国学者对页岩气成藏机制、成藏条件等进行了研究,已具有一定的认识。对我国页岩气研究进展进行了概述。结合前人的认识,将天然气的成藏分为吸附气产生、游离气流入基质等5个阶段,具有较好勘探潜力的页岩气藏是保持在第三阶段或以前的气藏;将页岩气藏成藏机制进行了进一步总结,对地层压力提出了新的认识。总的来说,中国页岩气的勘探开发还处于起步阶段,在理论研究的同时进行大胆实践探索应是目前的重点。

Inspired from a successful E & P of shale gas in USA,its E & P in China has been put on agenda.Both reser voir-forming mechanism and conditions have been studied since 2002 and some achievements have been made.Research shows that gas reservoir forming can be divided into five stages including adsorption-gas generation and free-gas flowing into matrix ;fur thermore,shale-gas reservoirs with better exploration potential are ones keeping in or before the third stage.In addition,its reser voir-forming mechanism is further summed up and a new under standing on formation pressure is put forward.In general,the E & P of China ' s shale gas is in a beginning stage.So,it is necessary to have a practical exploration besides theory research.
