摘要
煤层气储集层特征研究和评价是煤层气勘探开发战略选区的关键环节,文章采用瓦斯地质理论,对寺河井田3号煤层的含气性、含煤性、煤储层压力、煤层孔渗性及水文地质条件等煤层气储集层物性及特征参数进行了分析和研究,并采用模糊综合评价法对其进行了定量评价。结果表明:"3号煤层是煤层气的良好储集层,亦是煤层气勘探开发有利储层"。
Coalbed methane reservoir characteristics research and evaluation is a key link in the process of coalbed methane exploration and development strategy selection,this paper USES the theory of gas geology,hydrocarbon content of No. 3 coal seam in sihe mine,coal,coal reservoir pressure,permeability of coal seam and hydrogeological conditions of coalbed methane reservoir physical property and characteristic parameters are analyzed and the research,and USES the fuzzy comprehensive evaluation method for the quantitative evaluation. The results showed that： ＂No. 3 coal seam is a good reservoir of coalbed methane,is also the coalbed methane exploration and development favorable reservoir＂.
