中国页岩气勘探开发适用技术探讨

A Discussion on Applicable Technology for Exploration and Development of Shale Gas in China

页岩气藏因其储层物性差、孔隙度和渗透率低,使其开采难度大,需要应用特殊的勘探开发技术。美国在页岩气勘探开发中采用了致密岩石分析技术、录井和测井技术、水平井钻井技术、特殊的完井工艺以及水力压裂等储层改造技术。通过借鉴国外的页岩气技术,分析技术适应条件,结合国内现有技术,提出适合我国的页岩气勘探开发技术设想及未来发展方向。

Exploration and development of shale gas reservoirs are difficult due to the poor physical properties such as poor porosity and poor permeability etc.,and so special exploration and development technology is needed.Special technologies of analysis,mud logging,logging,horizontal well drilling,well completion and hydraulic fracturing etc.for tight rocks were used during exploration and development of shale gas reservoirs in U.S.Using their experience and our own technology,a tentative technological plan applicable for exploration and development of shale gas reservoirs in China is suggested.
