油势场的研究与应用

Study on Fluid Potential and Its Application

流体势是控制地下孔隙流体流动的基本动力,它决定着流体的流动方向,并最终影响油气的富集与成藏。通过研究油气的流体势场,我们可以确定油气的运移方向,判断油气的运聚成藏部位。本文主要研究了歧口凹陷沙一段中上部、沙一段下部、沙二段和沙三段在不同地质时期流体势场的分布与演化特征,并在此基础上指出了油气聚集的有利地区。

 Fluid potential is an important method of determining the direction of fluid migration, studying the law of oil and gas migration and accumulation, dividing oil and gas supply unit and hydrocarbon reservoir generation system and calculating the assignment of secondary migration. The character of oil fluid potential of Qikou sag in some different period is studied, and the favorable places of oil accumulation are pointed out.
