成庄井田西部煤层气产能主要地质影响因素

On the Main Geological Influence Factors of Coalbed Methane Production Capacity in the Western of Chengzhuang Minefield

通过分析成庄井田西部煤层气井产气量现状,结合该区煤层含气性特征、顶底板岩性、孔裂隙发育特征、储层压力、吸附特征与采收率,阐明影响煤层气产能的主要地质因素,为成庄井田煤层气开采提供依据。

In this paper, through the analysis of coal seam gas production situation in Western Chengzhuang Minefield, combined with the characteristics of coalbed methane, lithology of roof and floor rocks, the development of the fractures, the reservoir pressure, absorption characteristics and the recovery factor, and the main geological factors affecting coalbed methane production capacity are expounded to provide the basis for coalbed methane in Chengzhuang Minefield mining.
