Under experimental results of wax deposition and phase change, the mechanical characteristics of fluids flowing through porous media and the relevant physicochemical problem were all summed up as solving 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. Numerical simulation results proved that the flow resistance increased and the production output decreased owing to wax deposition.

在蜡沉积变相态渗流实验和渗流数学模型的研究基础上,引入蜡沉积数学模型、考虑毛管力和表面张力的相对渗透率模型等,建立了相应的多孔介质中气-液-固变相态多相流-固耦合渗流数学模型,数值模拟结果表明,蜡沉积可使都分区域孔隙减少,流动阻力增大,不考虑蜡沉积会对产量预测明显偏大,蜡沉积可使产量下降。
