| 摘 要： | 韩城矿区为我国煤层气勘查的重要区块,WL1井组位于象山煤矿西侧,区内煤层厚度大、发育稳定。根据WL1井组获得的煤储层参数可知,该区的煤层煤化程度R0为1.85%～2.05%,煤储层压力2.39～2.65MPa,渗透率为0.22～3.50mD,3号、5号、11号煤层含气量分别为8.38、8.46和6.63m3/t。区内构造简单,含煤地层富水性弱-中等。综合区内地质条件分析认为,韩城WL1井组是具有煤层气开发、生产潜力的区块之一。

| Abstract: | The Hancheng mining area is one of country＇s major exploration regions for CBM development. The WL1 well group is situated on the west side of the Xiangshan coalmine, coal seams in the area are rather thick and stably developed. According to the coal reservoir parameters obtained from WL1 well group, the degree of coalification R0 is 1.85%-2.05%, coal reservoir pressure 2.39-2.65MPa, permeability 0.22-3.50md, CBM content of Nos.3, 5 and 11 coal seams are 8.38, 8.46 and 6.63m^3/t respectively. Structure in the area is simple, coal-bearing strata water yield property weak to medium. After integrated geological condition analyses in the area considered that the WL1 well group region in Hancheng mining area is one of regions possess CBM development and production potential. |
