摘　　要：对于溶解气驱油藏,由于油藏流体的物理性质和相渗透率随压力而改变,所以油井产量和流压的关系是非线性的。通过对前人成果的归纳、分析和总结,规范统一了流动效率的概念。研究认为,将流动效率定义为在相同压差下非完善井的实际产量与理想完善井的产量之比更为合理,便于数学描述而且物理意义更加明确。所建立的流入动态关系适合于不同条件下的流动效率,具有实际应用价值。For the solution gas drive reservoir,the reservoir fluid physical properties and relative permeability changes with pressure,so the relationship between the producing flow rate and pressure is nonlinear.By analyzing previous results,the efficiency of a uniform regulation of the flow concept is developed.The results show that the flow efficiency is defined as the same pressure in the well under the actual production of non-perfect sound and the ideal ratio of production wells is more reasonable,but also to facilitate the mathematical description of the physical meaning more clearly.Into the dynamic relationship established for the efficient flow under different conditions,have practical value.
