摘　　要：基于所收集的页岩气基础地质资料及国内外公开发表的文献,分析了页岩的地球化学、储层、含气性、可采性等条件及页岩气构造保存条件对页岩气成藏和开采的影响,建立了相应的页岩气有利选区评价模型,并对评价指标进行了规范化处理。以我国页岩气勘探较为成熟地区为例,利用模糊物元分析法,确定了影响页岩气有利选区评价指标权重,并对这些有利区进行了综合评价和排序。结果表明,建立的页岩气有利选区评价模型是可行和合理的,与实际情况基本相符,评价结果可作为页岩气开发的决策依据。Based on the basic geological data of shale gas and published data related in literatures, an analysis of the geochemical conditions, reservoir conditions, gas-bearing properties ,rescoverability and preservation for reservoir forming and exploitation of shale gas was conducted to setup an evaluation model for the corresponding shale gas favorable area with every evaluation index quantitatively standardized. Some favorable shale gas development areas in China were taken for example to determine the evaluation criterion weight and evaluate the favorable areas by using fuzzy matter element analysis. The results show that, the shale gas favorable area evaluation model established is feasible, reasonable and close to practice, and that the evaluation results can offer the decision basis for developing shale gas resources.
