煤层气可采性综合评价方法研究——以潘庄井田为例

Integrated methods of CBM recoverability evaluation:A case study from Panzhuang mine

摘要: 文章对常规煤层气可采性研究方法进行了研究,分析了各种方法适用的条件以及存在的问题,指出煤层气的可采性需要在地质因素综合分析的基础上,研究主要控制性地质因素及其有效配置。多因素加权分析法与储层数值模拟法相结合是一种有效的煤层气可采性评价方法。并以潘庄井田为例,在系统分析了影响煤层气可采性主要地质因素的基础上,进行了煤层气可采性的综合评价。

Abstract: Adaptive condition and existing problems of various methods of coalbed methane(CBM) recoverability evaluation are discussed in the paper.It is important to study the effective configuration of main geological factors.The combination of multifactor weighted analysis with reservoir simulation is an effective means to evaluate CBM recoverability.Based on systematic analysis of main geological factors of Panzhuang mine,the integrated evaluation of CBM recoverability is performed.
