Study of characteristics of structure-controlled coalbed gas in southern Qinshui Coalfield

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.
