| 摘 要： | 依靠沉积相、沉积微相以及实测地层压力的差异对鄂尔多斯盆地古生界含油气系统进行划分，论证了奥陶系天然气藏落在一个含油气压力系统中。根据包裹体镜下观察、显微测温数据及激光拉曼成分测试数据的内在联系，将鄂尔多斯古生界沉积岩包裹体划分为9期次，在此基础上，利用包裹体地球化学数据计划了研究区4个期次的古流体势，进而根据古流体势判别研究区下古生界天然气成藏时期流体运聚情况。将运用沉积岩中流体包裹体研究油气运聚的方法系统归结为含油气压力系统的划分、运移期次分析和运聚方向判定等三方面的内容。

| Abstract: | Determined by characteristics of sedimentagraph, undersize sedimentary faces and field test pressure in Ordos lower Paleozoic, Ordovician reservoirs are of a pressure system of oil gas. After having worked out the periods of fluid inclusions by using data of Micro test of temperature and laser micro test of components, four periods fluid potential are obtained. It is summarized that research into the migration of oil gas using data of inclusions in sedimentary rocks comes to three parts: determining the pressure system of oil gas, the migrating period and migrating directions. |
