摘要
新疆地区新生代盆－山体制独特，深断裂活动既造山又造盆。活动带集中在山系及山前带，盆地内保存稳定地块区。吐哈盆地北部凹陷不存在大型盖层滑脱型推覆构造带。火焰山构造带受基底逆冲断裂控制，断裂控制背斜圈闭形成。油气沿隐伏断裂伴生的构造圈闭富集成藏。湖－沼相侏罗系含煤系是重要的油气源层，湖相三叠—二叠系亦有含油气远景。
The basin mountain regime of the Cenozoic in Xinjiang area is so special that the formation of both mountain and basin is associated with the activities of the deep faults. The mobile belts are distributed along the mountains and foreland while the stable blocks are preserved in the basins. There are no large slipping nappe structure belts on the north depression in the Turpan Hami basin. Huoyanshan structure belts are controlled by the basement thrusts. The formation of anticline traps is controlled by the faults. The oil gas pools occur in the structure traps that are distributed along the blind fault belts. It is pointed out that the Jurassic coal bearing strata of lacustrine marsh facies are very important source rocks. There exists an oil gas prospect in the lacustrine Permian Triassic System in the basin.
