技术进步是推动美国页岩气快速发展的关键

近年来，美国页岩气的勘探开发步入大规模快速发展阶段。除了得益于天然气市场需求的增长、国家政策扶持等因素外，技术进步是推动美国页岩气快速发展的关键因素，其中钻井、完井与增产技术的进步，尤其是水平井钻井、水力多段压裂、重复压裂、同步压裂以及裂缝综合监测等技术的突破与广泛运用起着极为重要的作用。美国页岩气勘探开发的巨大成功表明，只要突破传统的勘探思想，坚持不懈地开展技术创新，仍然能够使分布广泛的页岩气资源量逐步转化为经济和技术可采储量。

Prospects and strategic position of shale gas resources in China

Production of shale gas will get more prosperous and will expand rapidly along with technical progress and improvement of economic conditions. The prospects of shale gas exploration and production and the strategic position of shale gas resources in China are analyzed after introducing the domestic and foreign shale gas resource volumes. As required by the overall development strategy of petroleum industry in China, prospecting for natural gas reserves is a task of top priority. The organic rich shale formations were extensively deposited in different geologic periods in China and had favorable conditions for the generation and accumulation of shale gas. They have huge potentials of gas resources and bright prospects of exploration and production, and will surely become a major new field of gas exploration and production. It is proposed to strengthen research and increase exploration investment in shale gas. The shale and mudstone in the lower sequences in South China and those in the Mesozoic in North China have relatively large potential for shale gas exploration. It is proposed to perform gas testing or production test in the favorable intervals selected through reviewing old wells, so as to open a new stage of shale gas exploration through fanning out from point to area.
