页岩气开发目标区优选体系与评价方法

中国对页岩气的研究已经起步，但至今尚未建立完善的页岩气目标区优选体系，这制约了我国页岩气大规模工业化开发的步伐。在收集大量的页岩气基础资料和借鉴前人的研究成果的基础上，详细分析了页岩储层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。通过层次分析法确定权重，利用无量纲化指标处理方法对所确定的指标进行标准化处理，采用加权平均模型对目标区进行模糊综合评价。最后以中国部分页岩气试验区为例进行了综合评价、排序。其成果实际应用效果良好，能够有效地指导我国页岩气的勘探开发工作。

An optimal system and evaluation methods of ranking shale gas development prospective zones

The research of shale gas just started up so there is lack of a complete optimal system of ranking shale gas development zones,which significantly constraints the commercial shale gas production in China.In view of this,based on a great number of fundamental data and previous research results,a deep investigation was made into the impact of geological factors on the shale gas reserves abundance and the development response,thus a related evaluation index system of shale gas target zones was set up.The weigh...
