页岩气藏开发可行性的模糊层次分析法研究

Fuzzy analytic hierarchy method of shale gas reservoir development feasibility

目前由于我国页岩气开发起步较晚,国内外尚未深入开展页岩气开发可行性评价理论研究,急需形成一套页岩气藏开发可行性快速评价的理论和方法,为优选页岩气藏提供依据,达到科学快速开发页岩气藏的目的。为此,本文从页岩气地质特征及开发特点出发,对比国内外页岩气藏,筛选出影响页岩气开发的关键因素,利用模糊层次分析法建立页岩气藏开发多因素快速评价的理论和方法。结果显示,基于模糊层次分析法的多因素评价模型,对于页岩气藏开发可行性的评价是可行的,能够为页岩气藏开发有利区块的筛选提供指导作用。

Due to development of shale gas start late in China ,feasibility evaluation of shale gas development in theoretical research have not carried out at home and abroad .There is a urgent need to develop theory and method of the feasibility of the formation of a shale gas reservoir to achieve the scientific purpose of the rapid development of shale gas reservoirs .In this paper ,starting from shale gas geological characteristics and development characteristics and contrasting shale gas reservoir at home and abroad .using fuzzy AHP to establish shale gas development multifactor rapid assessment theory and methods .The critical factors affecting the development of shale gas are filtered out .The results show that the multi-factor evaluation model based on fuzzy analytic hierarchy process for the evaluation of the feasibility of shale gas development is feasible ,shale gas reservoir development a favorable area screening guiding role .
