Abstract

Models of poroelasticity and discrete fractures serve as a basis for a numerical study of a fluid flow in deformable fractured porous media. The influence of the stress-strain state of a medium on its flow properties is considered. Oil displacement from fractured formations is investigated. It is shown that compressive stresses have a significant impact on the efficiency of oil displacement. Calculations are carried out for three variants of randomly generated systems of fractures with different degrees of connectivity.

基于多孔弹性模型和离散裂缝模型的裂缝多孔介质中两相流体流动的数值研究

摘要

多孔弹性模型和离散裂缝模型是对可变形裂缝多孔介质中的流体流动进行数值研究的基础。考虑了介质的应力应变状态对其流动特性的影响。研究了从压裂地层驱油。结果表明,压应力对驱油效率有显着影响。对具有不同连通度的随机生成的裂缝系统的三种变体进行了计算。
