摘要
托克逊西南部是二叠系、三叠系生烃区,主要构造圈闭均有探井控制,但仅东部边缘发现伊拉湖小油田,与生烃区分布极不相称。本文通过已有的探井地质资料,分析了深层二叠系的地层结构与分布,论证了源于二叠系油源油藏的形成条件和特点,指出了深层二叠系隐伏圈闭、隐伏油藏存在的可能性。
The main structural traps in the southwest Tuokexun region, in the Permian and Triassic source area, are all controlled by exploration wells, but only a small oil field, Yilahu oilfield discovered at the edge of the east region can not match the source area. In this paper, the structure and distribution of the deep Permian formation are analyzed by the use of available geologic data. The generation conditions and characteristics of Permian source reservoir are demonstrated and the possibility of discovering deep Permian blind traps and reservoirs is pointed out.
