塔里木盆地下古生界海相烃源岩主要分布于满加尔凹陷,形成满加尔含油气系统,塔中隆起是其主要油气聚集区之一。通过对塔中隆起食油气系统事件的动态分析,认为塔中隆起在寒武纪至泥盆纪(加里东期至海西早期)经历了含油气系统发育—形成—破坏阶段;在石炭纪至第四纪(海西中期至喜山晚期)经历了含油气系统改造-重建阶段;其寒武-奥陶系烃源岩有二次生烃历程,具有多期油气混合成藏的油气藏基本特征。
The Lower Paleozoic marine source rocks in the Tarim Basin are mainly distributed in the Manjiaer Sag and form Manguer petroliferous systems. The Tazhong uplift is one of the major hydrocarbon accumulation areas. Based on the dynamic analysis of the food-gas system events in the uplift of the Tarim Basin, it is concluded that the Tazhong uplift experienced the stage of hydrocarbon-bearing system development-formation-destruction during the Cambrian-Devonian (Caledonian to early Hercynian) Quaternary (mid-Hercynian to Himalayan) experienced petroleum system reconstruction-reconstruction stage. The Cambrian-Ordovician hydrocarbon source rocks have secondary hydrocarbon generation history, with the accumulation of multi-period hydrocarbon reservoirs basic feature.
