摘　　要：应用Hubbert流体势计算方法 ,对丁家屋子断阶带孔店组顶界面和底界面的水势和油势进行了计算。在编制流体势平面和剖面等值线图的基础上 ,分析研究区的流体势分布特征。认为研究区的流体运移特征为 :在孔店组上界面发生纵向运移为主 ,在下界面发生横向运移为次。有利油气聚集带分布在孔店组上下界面、由构造———岩性组合而形成的圈闭和不整合面遮挡而成的地层圈闭区。此推断与目前的勘探结果不期而合。The principle of Hubbert fluid potential analysis was used to calculate the flow of water and oil at Kongdian Group's top interface and bottom interface on fracture belt at Dingjiawuzi. Based on the plane and section isoline of fluid potential, the distribution features of liquid flow in the studied areas were analyzed. These features were: the vertical migration occurred at Kongdian Group's top interface first and the lateral migration occurred at its bottom interface next. The movement made it possible for oil and gas accumulation zone to distribute at both the top interface and the bottom interface of Kongdian Group. This inference was in agreement with the present prospecting result.
