摘　　要：在Petrobras建立的完善井油、气、水三相流入动态关系基础上,考虑油井采取增产措施后对流入动态关系的影响,建立了超完善井的油、气、水三相流入动态关系数学模型。引用两相流动效率描述油井生产条件改善后对产能的影响程度,可用以计算改善油井的实际产油量。实例计算表明,超完善性对油井流入动态关系的影响比较明显,应用该方法可对其进行准确预测。Based on the inflow performance relationship of three phases of oil,gas and water in completely penetrating wells set up by petrobras,taking the influence of stimulation to IPR into account,mathematical model of inflow performance of three phases of oil,gas and water in super completely penetrating wells is established.Describing the influence degree of improvement of production condition to deliverability by two phase flow efficiency can be used to calculate the actual production rate of the treated oil wells.Field application showed that super completely penetration influences greatly the inflow performance relationship of oil wells,and this method can be used to predict accurately the IPR.
