摘　　要：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。Lower Palaeozoic marine hydrocarbon source rocks of Tarim basin are mainly distributed in Manjiaer depression, forming the Manjiaer petroleum system, of which, Tazhong rise is one of the major oil and gas accumulation regions.The performance analysis of the petroleum system event of Tazhong rise shows that the Tazhong rise underwent the development-formationdestruction stages during the period from Cambrian to Devonian (i. e. Caledonian to early Hercynian) and reworking and reconstruc1ion stages during the period from Carboniferous to Quatemary (i. e. from middle Hercyniao to late Himalayan).The Cambro-Ordovician source rocks had two hydrocarbon generation stages and have the basic features for oil and gas pools with multi-stage combination of oil and gas.
