摘要
在对喀什凹陷侏罗系烃源岩和圈闭类型、储集岩、盖岩等含油气系统基本要素研究的基础上,结合侏罗系油气运聚过程分析及构造演化总结,认为喀什凹陷侏罗系含油气系统可分为原生和后期改造2 个阶段。含油气系统演化上的差异决定了喀什凹陷不同地区勘探重点的不同,其中凹陷腹部处于原生含油气系统阶段,应以寻找砂岩体—岩性尖灭圈闭为主;山前构造带处于后期改造阶段,勘探的重点应为构造圈闭。
Based on studies on source, reservoir, seal rocks and traps of petroleum system, thermal evolution of source rock and tectonic evolution of the Kashi Depression are analyzed and modeled. Evolution of the Jurassic petroleum system in Kashi Depression can be divided into primary stage and rebuilt one, with different time and space range in different stages. Different oil space range suggests different exploration techniques. For primary petroleum system in the inner parts of depression, the target should be aimed at lithological traps. But for mountain front belts, the concentration should be structural traps.
