【摘要】：玛扎塔格断裂带的演化过程对塔里木盆地巴楚隆起和麦盖提斜坡油气成藏有着重要的控制作用.根据最新地震资料的精细解释和构造解析,分析了玛扎塔格断裂带的变形结构、样式和变形过程.玛扎塔格断裂带的变形分为上、中、下(深)3层结构,分别形成于不同时期.玛扎塔格断裂带变形的差异性主要体现在中层构造,从东往西控制中层构造发育的逆冲断层及其反冲断层的位移量不断加大,褶皱核部的剥蚀量也向西持续增加.玛扎塔格断裂带深部背斜构造存在发育盐下白云岩原生油气藏的可能,后期的变形没有破坏早期形成的深层背斜构造.玛扎塔格断裂带深部背斜构造的盐下白云岩是油气勘探的有利方向.
[Abstract]:The evolution of the Mazatag fault zone plays an important role in controlling oil and gas accumulation in the Bachu uplift and Megeti slope of Tarim basin. The fine interpretation and structural analysis are based on the latest seismic data. The deformation structure, style and deformation process of the Mazatag fault zone are analyzed. The deformation of the Mazatag fault zone can be divided into three layers: upper, middle and lower. The difference of deformation in the Mazatag fault zone is mainly reflected in the middle structure, and the displacement of the thrust fault and the recoil fault controlled by the middle structure from east to west is increasing. The denudation of the fold core is also increasing westward. The deep anticline structure in the Mazatag fault zone has the possibility of developing subsalt dolomite primary oil and gas reservoirs. The late deformation did not destroy the early formed deep anticline structure. The subsalt dolomite of the deep anticline structure in the Mazatag fault zone is the favorable direction for oil and gas exploration.
