渗透性岩层介质油水两相渗流分析

Oil-water Two-phase Seepage Analysis of Permeable Formations Medium

准确模拟油藏中的流体流动过程,提示流体的分布规律,必须考虑由于注水和开采所引起的多相流体的渗流、应力状态的变化和储层变形之间的耦合作用。近年来引起中国学者的极大兴趣,成为油藏工程及相关领域研究的热点问题之一,基于岩石力学、渗流力学、地质力学、计算力学以及流固耦合渗流的基本理论,建立了多孔介质渗流场和应力场耦合的数学模型,采用有限元法进行了程序设计,通过数值模拟方法对渗透岩层介质井眼周围油水两相渗流规律进行了研究,用于解决实际工程问题。

Simulate the flow process of reservoir fluid accurately and reveal the fluid distribution law, it must be considered that multiphase fluid seepage caused by water injection and exploitation, the change of stress state and the coupling between the reservoir deformations, In recent years, it caused than the great interest of chinese scholars, one of the hot topics is become the reservoir engineering and related field of research. According to the basic theory of rock mechanics, fluid mechanics in porous medium, geologic mechanics, calculated mechanics and fluid-solid coupling seepage, a mathematical and numerical model of seepage field and stress field coupling is developed in porous medium and a computer program is designed with the method of finite element technique, With the methord of numerical simulation ,oil-water two-phase seepage rule of permeable rock medium is studied for solving actual project problem.
