京西地区石炭—二叠系页岩气勘查技术方法浅析

Discussion on the Exploration Technique of Carboniferous-Permian Shale Gas in Western Beijing

京西地区尚未开展过油气地质调查工作,本次在京西地区首次开展页岩气资源前景调查评价工作,为了确定富有机质泥页岩形成的沉积构造条件、时空分布规律、成气地质条件,应用了地质调查法、地球物理法、钻井法、实验分析法,综合分析页岩气成藏地质条件。并对京西凹陷页岩气勘查技术方法进行了初步探索,对今后工作开展具有重要的参考价值和示范作用。

It has not yet carried out geological survey of oil and gas in western Beijing; this paper fi rstly carried on the investigation and evaluation on the shale gas in western Beijing. In order to discover the rich organic shale＇s depositional background, characteristics and distribution, g eneration mechanism of shale gas,this paper adopted the comprehensive methods： regional survey and outcrop profile, geophysical techniques, borehole techniques, shale gas test experiment,and analysis of the reservoir-forming conditions of shale gas. It preliminary discusses the shale gas exploration technology method used in the western Beijing sag. It provides valuable experience for the shale gas resources geological exploration and plays an exemplary role and reference.
