摘要:
三塘湖盆地侏罗系低煤阶煤层气资源丰富。以钻井资料和煤岩实验分析资料为基础,系统分析了侏罗系煤层发育特征与煤层气成藏地质条件,明确了煤层气成藏模式和资源潜力,并预测了勘探有利区。研究结果表明:①三塘湖盆地侏罗系发育八道湾组、西山窑组 2 套含煤地层,厚煤层主要发育于汉水泉凹陷、石头梅凸起、条湖凹陷、马朗凹陷、淖毛湖凹陷等聚煤中心;主要为原生结构煤,煤岩有机组分以镜质组为主,惰质组次之;镜质体最大反射率(Ro max)为 0.22%~0.77%,为低阶褐煤和长焰煤。②煤岩储层物性较好,属中等孔隙度、低—中渗透率储层;主要发育介孔,孔径主要为3~10 nm。③研究区煤层气的质量体积为 0.11~7.68 m3/t,气体组分主要为N2、CO2、CH4,其中CH4含量最高,体积分数达到85.50%~91.24%,马朗凹陷、淖毛湖凹陷煤岩含气性条件最好。④研究区顶底板组合类型有顶底泥岩型、顶泥底砂型、顶砂底泥型和顶底砂岩型等4种,顶底泥岩型对煤层气封闭性能最好;煤层气富集模式可分为凹陷滞留富集成藏模式、逆断层岩性封堵成藏模式和凸起径流逸散模式。⑤研究区煤层气资源量为4 750×108 m3,平均资源丰度为0.80×108 m3/km2;条湖凹陷深部、马朗凹陷深部、淖毛湖凹陷深部为煤层气勘探Ⅰ类有利区。
