摘　　要：在Petrobras推导的完善井的油、气、水三相流入动态关系基础上,考虑了油井的不完善性对流入动态关系的影响,建立了不完善井的油气水三相流入动态关系数学模型,完善了油气水三相流入动态理论体系。引用二次式流动效率描述油气两相流时油井不完善性对产能的影响程度,可以计算不完善井的最大产油量。实例计算表明,油井的不完善性对产能存在不同程度的影响,应用本文方法可以预测不同流动效率下的油气水三相流入动态。Petrobras established inflow performance relationships of three-phase for imperfect wells.On the basis,taking the influence of well damage to inflow performance relationships into account,this paper derived a mathematical model of three-phase inflow performance relationships for damaged wells and improved the theoretical system of three-phase inflow performance.By adopting the two-phase flow efficiency to describe the influence of well imperfection on deliverability,the maximum production of imperfect well can be calculated.Examples show that well imperfection will affect deliverability in varying degrees.The three-phase inflow performance under different flow efficiency can be predicted according to the method presented in this paper.
