The Finite Element Analysis of Coupling Law of Single Phase Stress Field / Seepage Field in Permeable Stratum Medium
The research of reservoir fluid-solid coupling theory is hot issues in home or foreign recently, In oil, civil, environment and geology, mining and other fields with a wide application. On the basis of summarizing the predecessors' achievements，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 the LiuNan blocks of JiDong oilfield wells.based area single phase Stress Field / Seepage Field in solving with the method of finite element software ANSYS, Contrast analysis of LiuNan blocks Coupling around of Field / Seepage Field is the change of average stress and total displacement. As can be seen from Table 3, after coupling the value of average stress and total displacement are greater than before coupling.The results show than it is important meaning for used to solve practical engineering problems.
