煤层气含气性主控因素探讨

Discussion of the Main Factors of Coalbed Methane Gas

煤层气含气性是煤层在一定地质条件下储集煤层气的数量和能力,它是由煤层气的生产和保存条件以及地质控制因素决定的。煤层含气性是评价煤层气勘探开发前景的重要因素,它是煤层气远景评价和选区的重要基础。以沁水盆地南部为研究区,从顶底板岩性、构造和水文地质条件等方面讨论了煤层气含气性和可采性主控因素。

Coal bed methane gas is the amount under certain geological conditions and the ability of coalbed methane reservoir; it is by the production and storage conditions and geological factors controlling coalbed methane decision. Gas in coalbed methane exploration and development prospects to evaluate an important factor, it is an important basis for coalbed methane prospect evaluation and selection. In the southern Qinshui Basin as the study area, discuss the factors that coalbed methane gas and admissibility of the main terms of roof and floor lithology, structure and hydrogeological conditions.
