摘要(Abstract)：

分析库车拗陷钻井和地球化学资料,研究页岩气聚集的条件.结果表明:库车拗陷侏罗系—三叠系泥页岩有机碳质量分数高,集中分布在2.0%~3.0%之间;泥页岩厚度大,多数在200 m以上;干酪根类型以倾于生气的腐殖型为主;有机质成熟度分布较广,从0.6%~3.0%均有分布,主要集中分布在2.0%附近,有机质处于成熟—高熟阶段,具备形成页岩气的物质基础.库车拗陷构造活动强烈,逆掩断裂发育,为该地区泥页岩中天然裂缝的发育提供条件,有利于页岩气的富集和实现工业开采.利用多因素叠合法对库车拗陷页岩气有利聚集区进行预测,认为侏罗系页岩气聚集的有利区为拜城拗陷及克依构造带上,三叠系页岩气聚集的有利区集中分布在拜城拗陷,而在克依构造带有部分分布.
