The condensate gas liquid-solid of multiphase complex flow is complicated with phase change and wax deposition. In the process of condensate gas percolation flow in reservoir, gas-liquid-solid may be thransformed with phase change, which will result in the change of distribution of fluid pressure and influence or alter the characteristic and the process of condensate gas percolation flow accordingly, the porous flow mathematic models of multiphase complex flow with phase change and wax deposition is founded. The mechanical characteristics of fluids flowing through porous media and the relevant physicochemical problem may be all summed up as sloving the gas-liquid solid coupling mathematical model. After considering the phase change action between condensate gas and condensate liquid , wax deposition, interlarded with interfacial drag force and capillary pressure engendered in the process of phase change, laying a theoretical foundation for studying and predicting the production behavior of condensate gas
