页岩气开发区优选研究

Study On Shale Gas Development Evaluation

中国页岩气勘探开发持续升温,为了降低勘探风险,建立完善的页岩气目标区精选体系是十分必要的,有利区块的优选可为进一步勘探决策和深化研究提供重要的依据。本文首先详细分析了页岩气地质因素对页岩气富集丰度和开发效果的影响,建立了相应的页岩气目标区评价指标体系,然后通过模糊数学方法对目标区进行综合评价。最后以中国部分矿区为例进行了综合评价、排序,实际应用效果良好,能够有效地指导页岩气勘探开发。

With th opment evaluation e quickening step of shale gas exploration and development in China, establishing shale gas devel- model is very necessary to reduce the exploration risk. The optimization of favorable area can pro- vide an important basis for further decision-making of the exploration and further study. First of all, the influence of geological factors in shale gas reservoir to the enrichment abundance and the development effect of shale gas is ana- lyzed detailedly, and the relevant assessment index system of shale gas perspectives is built. Then the perspectives is comprehensively evaluate by fuzzy mathematical method. Finally, some shale gas regions in China are compre- hensive evaluated and screened. The result is so good in practical applications that it can be used to effectively guide the exploration and development of shale gas.
