煤层气富集区地球物理综合评价方法研究——以长治地区为例

Research on Geophysical Comprehensive Evaluation Method of Coalbed Methane Enrichment Region-Taking Zhengzhuang Region for Example

本文紧紧围绕影响煤层气富集的主控因素,从构造特征研究、煤储层预测研究和岩电特征研究三方面展开工作,探索出了一套适合于煤层气地质特点的地球物理综合评价方法。研究表明,用这套方法对沁水盆地煤层气富集区进行评价,优选区块与实钻结果吻合程度较高,对煤层气的勘探开发有重要指导意义。

This article concentrating on the main controlling factors of coalbed methane enrichment,based on the studies of tectonic characteristics,coal reservoir prediction research and rock electrical characteristics,finds a geophysical comprehensive evaluation method suitable for coalbed methane geological characteristics.Studies show that using this method to optimize coalbed methane enrichment region in Qinshui Basin,the block selection conform well with the drilling results and this method has an important guiding significance for the coalbed methane exploration and development.
