“…Nevertheless, as an effective and convenient method, equation (1) is also applied in the porous material region. This condition also indicates that the moving mesh velocity in ALE formulation is identical with the solid velocity, so it shows as follows w~d s (8) Interpolation is applied to the entire porous domain to obtain the fluid pressure on solid mesh and fluid nodal displacements, respectively. The porosity indicates that the fluid volume percentage in the total volume is no longer a constant in coupled porous media.…”

“…Those finite element models are symmetric around pipes' axes, high finite element mesh refinement and residual stress were predicted. 8,9 Since the fluid-solid systems were first introduced by Bathe and Hahn in 1978, 10 the theory of fluid-solid coupling has developed rapidly. The influence of fluidsolid coupling on liquid-conveying pipeline was investigated; transfer matrixes and finite element equations were also studied.…”

Deformation of underground rocks, also named rock creep, is treated as porous materials which usually results in many engineering problems, especially in petroleum engineering. However, it can be controlled by fluid-solid interaction in porous materials, and the deformation mechanism of underground rocks with fluid-solid interaction was analysed by finite element computing method. Specifically, an Iterative computing method and a computational procedure of two-way fluid-solid coupling are used to simulate deformation process until the fluid and solid solution variables are fully coupled. A typical application example was taken in Jinzhou oil production plant of Liaohe Oil Field Company, and a finite element model is built by combined application of parasolid and native modelling methods. According to the calculation results, deformation mechanism of underground rocks is proposed, and some advice is also presented.
