摘要
塔里木中新生代前陆盆地十分发育,油气资源潜力大,目前已发现10多个油气田,前景广阔。它的演化经历了早期前陆、晚期前陆及陆内统一盆地等3个阶段;按其动力学性质又可划分为单前陆、双前陆及走滑前陆等盆地;它的构造变形十分复杂,盆地构造样式为压性逆冲断裂;在平面上可划分为逆掩带、断褶带、坳陷带及斜坡带;其油气主要分布在断褶和斜坡带中。
The Mesozoic-Cenozoic foreland basin is quite common in the Tarim basin with great potential for oil and gas. By now,10 fields have been found. Evolution of the Tarim foreland basin can be divided into 3 stages: early stage, late stage and intracontinental integration. According to dynamic characteristics, it can also be divided into single foreland, double forelands and strike-slip foreland basins. Tectonic deformation is complicated and the main tectonic style is compressional reversing fracture. Horizontally it can be divided into overthrust zone, fault-fold zone, depression zone and slope zone.Oil and gas are mainly distributed in the fault-fold and slope zones.
