摘要(Abstract)：

有利的成藏条件是"连续型"致密砂岩气大规模聚集成藏的重要基础,明确成藏条件对于致密砂岩气藏理论研究和勘探实践具有重要意义.文中讨论库车拗陷侏罗系阿合组"连续型"致密砂岩气藏形成所需要的烃源岩、致密砂岩储层、盖层条件及构造条件.结果表明:下伏三叠系烃源岩为致密砂岩气藏的形成提供充足的气源,广泛分布的致密砂岩储层控制致密砂岩气藏在时间和空间的分布范围,致密储层上覆煤系地层与下伏泥岩为致密砂岩气成藏提供保护作用;后期的强烈构造活动,一方面促进地层快速沉降,有利于烃源岩快速演化,另一方面对致密砂岩气藏具有调整改造的作用,构造裂缝改善储层的物性,同时形成天然气散失的通道.因此,有利的源岩、储层、源储配置关系、盖层及构造活动是库车拗陷东部侏罗系"连续型"致密砂岩气藏形成的有利条件.

关键词(KeyWords)：“连续型”致密砂岩气藏;成藏条件;库车拗陷;侏罗系;烃源岩
