| 摘 要： | 采用岩相统计方法,对煤层甲烷的封盖条件进行了研究。提出了以封盖能力综合指数(SCI)对煤层甲烷封盖能力进行定量评价,并对研究区主采煤层甲烷的封盖能力进行了区域预测。预测结果表明:研究区封盖条件类型为Ⅱ-Ⅳ类,大部分地区属于Ⅲ类中等封盖程度。封盖能力较强区域位于研究区西部、东南部和东北角,均属于Ⅱ类封盖类型,其余地区为Ⅳ类。

| Abstract: | The paper used lithofacies statistical method to research the capped qualification of the capped coalbed stratum.Synthesis capped ability index(SCI) has been put forward to estimate the capped ability of coalbed gas quantificationally,and the capped ability of the capped stratum of the main exploited coalbed in the researching region was regionalized-forecasted.The research results indicated that the cap types of the researching region were kinds of from Ⅱ to Ⅳ,most regions belonged to Ⅲ which had the middle capped ability.In the western,southeast and the corner of northeast the researching region,there were rather strong capped ability,all of which belonged to Ⅱ,and other regions were the kind of Ⅳ. |

| Keywords: | coalbed gas synthesis capped ability index capped condition type capped condition regionalism |
