塔里木盆地周缘存在着强烈的新构造运动,主要表现为强烈的逆冲推覆构造,下更新统西域组(Q1x)在盆地周缘不同地区逆冲推覆在不同的地层之上或者被不同时代的老地层所覆盖,同时其也卷入了不同规模的褶皱之中。三维地震资料的精细解释显示塔里木台盆区志留系以上的地层因新构造运动而产生了区域性的构造反转,不同层位的地层顶面构造高点发生了向南迁移。新构造运动对塔里木盆地油气的控制作用表现为:在塔里木盆地的周缘形成了有利于晚期成藏的大型构造圈闭,并为晚期油气运移提供了成藏的强大动力;对早期形成的古油藏圈闭条件的改造和破坏,导致了古油藏内的油气发生重新运移,从而形成了具有复杂油水界面的现今正在充注的新油藏。
There is a strong neotectonic movement in the periphery of the Tarim Basin, which is mainly characterized by a strong thrust nappe structure. The Lower Xiluo Formation (Q1x) thrusts and pushes over different strata in different parts of the periphery of the basin, Old strata are covered, and they are also involved in the folds of different sizes. The detailed interpretation of the 3D seismic data shows that the strata above the Silurian in the Tarim Basin produced a regional structural inversion due to neotectonic movement, and the migration of the top structural highs of different strata to the south occurred. The neotectonic movement controls the oil and gas in the Tarim Basin by forming a large structural trap that favors late accumulation in the margin of the Tarim Basin and provides a strong driving force for hydrocarbon accumulation in late hydrocarbon migration. The alteration and destruction of trap conditions in the reservoirs have led to the re-migration of hydrocarbons in the paleo-reservoirs, thus forming a new reservoirs currently being filled with complex oil-water interfaces.
