| 摘 要： | 首先叙述了地应力作用下空隙弹性介质中流体运移的基本方程及由基本方程推导的有限元公式。然后，在地应力测量及构造分析的基础上，应用所出的有奶元公式及相应程序，对辽河油田运移势场进行了模拟，得出了该区运移势场的分布。结果表明，处于运移势低势区及过渡区的地区大部分是有希望的油田地区。结合构造分析进行应力和运移势场研究可为油气勘探开发提供依据。

| Abstract: | In this paper are described first the differential equation and finite element formula for fluid migration under the action of crust stress in a porous rock. Then the oil migration potential field in Liaohe oil field are calculated by using finite element method based on crustal stress measurement. The result shows that most prospective oil fields are in low migration potential areas and transition areas from low to high migration potential. The study combining oil migration with tectonic analysis may provide the basis for exploration and development of oil and gas field. |
