COUPLING WAVE PROPAGATION MODEL THROUGH POROUS MEDIA IN ARTIFICIAL VIBRATION OIL PRODUCING

Based on the research of coupling wave propagation model in artificial vibration oil producing technology, it is thought that the underground media is composed of deformable solid skeleton and fluids that saturate the pores in the skeleton. wave is not only propagated through solid skeleton but also through fluids. Thus the considered problem is a coupling wave. This paper introduces various physical models of artificial vibration oil producing, and presents the control differential eauations of coupling wave propagation. To deal with the wave propagation problems in infinite domain, nonreflecting boundary conditions, which are available for transient analysis, are recommended. The formulae of finite element method to solve this problem ase given combining with appropriate instant integration schemes.
