沁水盆地安泽东地区煤层气含量影响因素分析

Analysis of Influencing Factors of Coalbed Methane Content in Anze East Area of Qinshui Basin

安泽东地区位于沁水盆地中段西部,安泽县境内。由于煤层埋藏较深,勘查程度相对较低,以往对该区的煤层气研究较少。根据现有的勘查资料,通过分析影响研究区煤层气含量的各项因素,认为研究区煤的变质程度、煤层顶板岩石类型、构造和水文地质是如今煤层气含量赋存分布的主要控制因素。

Anze east area is located in the west of the middle section of Qinshui basin,within the territory of Anze county.Because the coal seam is buried deep and the exploration degree is low,there are few researches on the coalbed methane in this area in the past.According to the existing exploration data,through the analysis various factors affecting the coalbed methane content in the study area,it is considered that the metamorphic degree of coal,the rock type of coal seam roof,the structure and hydrogeology are the main controlling factors for the occurrence and distribution of coalbed methane in the study area.
