由石油勘探开发科学研究院和石油大学(北京)共同完成的“吐哈盆地及油气资源评价”综合研究,于1996年5月通过吐哈石油勘探开发指挥部组织的专家评审.该项研究历时两年,取得如下成果.1.盆地构造演化 确定了吐哈盆地演化阶段及产生的四大构造层序,划分出南北两大前陆盆地带,指出中、深层是生储油岩系与油气聚集的主要发育层段.同时,对全盆地构造样式和组合进行了重新解释:在北部凹陷带划分出上、下两个滑脱系统,下滑脱系前锋带控制着北部凹陷带侏罗系的主要油气聚集与分布;盆地西部存在胜南—玉果古弧形构造带,北东向构造带在盆地内发育最好,并控制了主要的油气聚集;盆地北部凹陷带存在3~4条撕裂断层,将凹陷带切割成4~5个块体.侏罗纪吐哈盆地经历了三大湖侵期,三大沼泽发育期.三角洲是侏罗系主要储油岩系.
A comprehensive study on Turpan-Hami Basin and evaluation of oil and gas resources jointly completed by the Institute of Petroleum Exploration and Development and the University of Petroleum (Beijing) was reviewed by experts organized by Tuha Petroleum Exploration and Development Command in May 1996. The study lasted In the past two years, the following achievements have been achieved: 1. Basin tectonic evolution The sequence of the four major tectonic processes in the Turpan-Hami basin and the two major foreland basins have been identified, indicating that the middle and deep layers are the source rocks and hydrocarbon reservoirs In the meanwhile, tectonic styles and assemblages of the whole basin are reinterpreted: the upper and lower slippage systems are divided in the northern sag zone, and the declination striker belt controls the main Jurassic in the northern sag zone There is an ancient arc-shaped Shengnan-Yuguo tectonic belt in the western part of the basin. The NE-trending structural zone is the best developed in the basin and controls the main hydrocarbon accumulation. There are 3 ~ 4 tearing in the northern depression Faults, the sag zone is cut into 4 to 5 blocks.The Jurassic Turpan-Hami basin experienced three major lakes and three marsh developmental stages.The delta is the main Jurassic oil-bearing rock series.
