基于模糊优化分析法的页岩气开发选区模型

在综合考虑地质条件、经济效益、环境影响等多方面影响因素的前提下，并在收集了大量的页岩气基础资料和借鉴前人研究成果的基础上，详细分析了页岩储层地质因素对页岩气富集程度和开发效果的影响，建立了相应的页岩气开发核心区选区模型。根据指标选择原则建立页岩气开发核心区选区评价指标体系，并对各指标数据进行定量规范化处理。通过专家评议和层次分析相结合的方法确定评价指标的权重。最后以我国一些具体的页岩气开发有利区为例，利用模糊优化法对这些有利区进行综合评价，通过结果分析，最终优选出可进行试验开发的页岩气开发核心目标区。

Shale gas development evaluation model based on the fuzzy optimization analysis

On the basis of comprehensive consideration of the geological conditions，economic，and environmental impact of various factors，combined with abundant collection of shale gas basic information and reference on the previous research achievements，a detailed analysis of the geological factors on shale gas accumulation and production was done to set up a corresponding shale gas core area selection model.According to the index selection principle to establish the evaluation index system for the shale gas development optimization，and every index data were quantitatively standardized.The weights of evaluation indexes were determined by means of expert evaluation combined with hierarchical analysis method.Finally，authors took some specific favorable shale gas development areas for example in China，by using fuzzy optimization method to evaluate the favorable area，according to analysis of the results to select core areas for shale gas experimental development.
