笔者通过胜利油区惠民凹陷南坡地区古生代地层的沉积相发育与分布特点的研究,并结合区域构造运动,揭示了该地区早古生代奥陶纪到中生代侏罗纪的构造和沉积体系发展演化规律。结果表明,整个研究区在早古生代发育了一套碳酸盐潮坪体系,晚古生代为海陆过渡的三角洲沉积体系,中生代为一套陆相河流体系。三角洲体系又包括了石炭纪的海相三角洲和二叠纪的陆相湖泊三角洲。该区在古生代和中生代经历着多期次、多类型的构造 沉积演化,从整个演化过程来看,总体上体现了从海到陆的过程。在空间上,除了在早古生代沉积相对稳定外,晚古生代和中生代均表现了较明显的沉降差异性。
Through the study of the sedimentary facies development and distribution of the Paleozoic strata in the southern slope of Huimin Sag in Shengli Oil Region and the tectonic movement of the area, the evolution and evolution of the Early Paleozoic Jurassic tectonic and sedimentary systems in the area from the Early Paleozoic to the Mesozoic law. The results show that there is a set of carbonate tidal flat system in the whole Paleozoic. The Late Paleozoic is deltaic sedimentary system of sea-land transition. Mesozoic is a continental river system. The delta system also includes the Carboniferous marine delta and Permian continental lake delta. In the Paleozoic and Mesozoic, the area underwent multi-stage and multi-type tectono-depositional evolution. From the point of view of the whole evolution process, the whole area embodies the process from sea to land. Spatially, except for the relatively stable deposition in the Early Paleozoic, the Late Paleozoic and Mesozoic showed obvious differences in sedimentation.
