| 摘 要： | 运用含油气系统的原理和方法,对塔里木盆地塔中地区油气藏形成条件进行了分析.区内发育寒武系一下奥陶统灰岩、泥灰岩和中上奥陶统泥灰岩等两套烃源岩,现今商业性油气藏主要以中上奥陶统泥灰岩为烃源岩.综合地球化学和测并资料确定了中上奥陶统有效烃源岩的大致分布范围.文中讨论了含油气系统的主要事件,包括排烃期、圈闭形成和油气运移等,并在此基础上,对塔中地区油气勘探区带进行了初步评价.

| Abstract: | The petroleum system concept and method are applied to the research work in Tazhong area. Two sets of hydrocarbon source rock have been found in the area,including the Cambrian-lower Ordovician and the middle Ordovician. The most valuable petroleum accumulations are originated from the middle Ordovician source rock. The distribution of effective hydrocarbon source rock is determined by combining geochemical data and logging data. The events of petroleum system are discussed,such as hydrocarbon extraction,trap formation and hydrocarbon migration. Based on these research work petroleum plays are evaluated. |
