Summary:Complex flow in reservoir of waxy condensate gas is study using numerical methods consider some changing factors, for instance: paraffin precipitation, phase transition, change of pressures and so on. Based on phase equilibrium theory, according to different Regions' seepage characteristics, consider so influencing factors as investigate gas-liquid-solid phase transition, inter-phase mass transfer, heat exchange and porosity change of reservoir to establish quality and energy conservation equation, which can gain the mathematical model of quasi-stable productivity to oil and gas wells. Then, the numerical simulation to oil and gas well drilling engineering will be carried out. Result display, paraffin precipitation can be resulted in the changes in property of pore of different regions' reservoir, which have a deep affect on production of oil and gas well. However, this can provide basis for rational mining of paraffin condensate gas reservoir.
