摘　　要：针对目前胜利油田生产井高含水、低产液等特点,迫切需要一套获取各产层产液情况及地层参数的动态监测手段。为此结合单相井、油水两相井的动态评价模型,提出了一种改进的变流量测井方法。在最小二乘原理基础上,根据变流量测井所测得的流量与井筒流压资料建立目标函数反求地层参数。通过对胜坨3区4口井实测资料处理结果与理论分析结果对比来看,该方法简单、可靠,而且可以达到分层求取地层参数的目的。In consideration of the characteristics of high water cut and low-yielding flow in Shengli Oilfield,there was an urgent need for a new dynamic monitoring method to obtain production rate and parameters of each producing layer.An improved variable flow logging method was proposed based on dynamic evaluation models of single-phase well and oil-water well.Formation parameters could also be obtained by an object function established by wellbore flowing and pressure data gained through variable flow logging based on least square theory.The method used in four wells in Shengtuo Region 3 was compared with the theoretical analysis,it shows that the new method is convenient and reliable.And the purpose of obtaining formation parameters of each layer is achieved.
