煤层气综合评价技术初探

根据对辽河断陷盆第三纪含煤地层资料统计，分析煤层含气的地质控制因素及其孔隙结构，提出煤层孔隙度背影值概念，采用Ｒ．Ａｇｕｉｌｅｒａ和Ｆａｉｖｒｅ两位学者提出的方法，计算煤层孔隙度和渗透率，并充分利用地质和测井资料，探索了一种煤层气评价的方法。

Preliminary Study on Integrated Evaluation Technique of Coalbed Methane

In light of the statistics of early Tertiary coalbed in Liaohe depression, the geological controled factors and pore structures of methane bearing coalbed are analyzed. The concept of coalbed porosity background value is put forward, the porosity and pemeability of coalbed calculated with the method proposed by scholars R. Aguilera and Faivre. The investigation of new method to evaluate coalbed methane is under way utilizing the geological and logging information.
