摘　　要：通过流体包裹体均一温度测试、含油气包裹体指数GOI统计和盆地模拟,研究了渤海湾盆地辽河西部凹陷南段的油气运移史,预测了油气聚集的有利地区。包裹体均一温度资料表明,本区有三期成藏:东二期、东一期和明化镇期;以前两期为主。盆地模拟研究表明,尽管沙河街组烃源岩在沙一期末开始生烃,但在东营期才开始大规模排烃和成藏。GOI的统计分析表明,GOI>5%的区域为油气聚集的有利地区,其中的圈闭应成为下步首选的钻探目标,已发现的欢喜岭油田和双南油田就分布在GOI>5%的区域内。The history of petroleum migration was studied and the favorable areas for petroleum accumulation were predicted in the southern Liaohe West Depression via the methods of testing the fluid inclusion homogenization temperatures, statistical simulation of grains containing oil inclusions （GOD, and basin modeling. The homogenization temperature test results suggested that the petroleum migration of the southern Liaohe West Depression were divided into three stages, Ed2 ,Ed1 and Nm,with Ed2 and Ed1 were the main stages. Basin modeling results further inicated that Shahejie Group began to generate petroleum in the end of Es1 period, but hydrocarbon migrating and accumulating were extensive during the period of Ed. GOI contour map revealed that the favorable oil accumulation areas were those with GOI greater than 5 %, and these areas should be selected as the preferred targets of drilling exploration. The results of this study are supported by the fact that the Huanxiling Oilfield and Shuangnan Oilfield both locate in the GOI greater than 5 % areas.
