在构造活动强烈、水动力条件活跃的地区,油气藏的分布位置与构造圈闭不一定完全匹配,它们之间可能有一段位移。如何利用现有的油、气、水资料预测油气藏的分布位置,Dahlberg于1982年提出了油气藏的水动力圈闭勘探法(U-V-Z法).本文介绍其原理和在南堡凹陷柳赞油田Es3(5)地层实际应用的情况,不仅预测了油藏的分布位置,还合理解释了所谓“水洗层”现象。

In the areas that are characterized by intense tectonic activities and active hydrodynamic conditions, the distributive location of an oil/gas pool does not coincide with structural trap, and there is a displacement between them. In 1982, Dahlherg proposed an oil/pool exploration method of hydrodynamic trap, using the data of oil, gas and water available. The paper introduces its principles and application to Es3(5) Formation in Liuzan oilfield, Nanbu depression, in which case it not only predicted the distributive location of oil pools, but gave reasonable explanation for the phenomenon of waterflushed layers.
