摘　　要：对于溶解气驱油藏,由于地下流体为油气两相流动,油藏流体和相渗透率将明显地随压力而改变,因而溶解气驱油藏油井产量与流动压力的关系是非线性的。研究中,用油藏数值模拟方法,结合非线性渗流理论,建立了溶解气驱油藏水平井的产能计算模型。经过效验,计算结果可以达到较高的精度。Fluids in solution gas drive reservoirs are two phase flow of oil and gas. The fluids and relative permeability will change with reservoir pressure, and the relationship between oil production and flowing pressure is nonlinear. A productivity model of horizontal wells in solution gas drive reservoirs is established by using numerical simulation in conjunction with nonlinear seepage theory. It has been verified that the calculation result is highly accurate.
