The Numerical Analysis of Complicated Gas-liquid-solid Flow in Reservoir of Waxy Condensate Gas
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-liquidsolid phase transition, interphase 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 result in the changes in property of pore of different regions’reservoir, which have a deep affect on production of oil and gas well. But this can provide basis for rational mining of paraffin condensate gas reservoir.
