摘要: 从构造对煤层、煤层气的生、储、存的控制作用出发,对晋城矿区大宁二号、潘庄一号、二号和樊庄四井田的地质资料进行了分析,研究了构造对煤层气赋存的特征,预测出各井田中间部位为富集带,是开发的首选目标。Abstract: Based on the analysis of structure control of coalbed gas generation,storage and keep,it is analyzed that the geologic data from wells of Daning No.2,Panzhuang No.1,No.2 and Fanzhuang No.4 mining districts of Jincheng mining area as well as the structure controlled characteristics of coalbed gas storage.The study results indicate that the centers of every mining districts are gas enrichment belts,being target areas for gas development.
