摘　　要：为了准确测量和评价水平井油水产出剖面,将水平井油水两相流动态测量实验和数值模拟相结合,建立了水平井油水两相分层流分相流量测量方法。实验中将微涡轮和微电容组合测井仪置于井筒截面不同高度处同步测量局部流体速度和持水率,研究了油水两相分层流水平井中不同总流量和含水率情况下5个测量点处涡轮及电容传感器的响应特性。采用持水率插值成像算法确定局部流体性质和油水分界面高度,将局部流体速度的涡轮测量值与数值模拟计算值相结合建立了过流截面速度场分布最优化计算模型,进而实现了水平井油水两相分层流分相流量的测量。5个测量点处流体速度的实验测量值和理论计算值基本一致,计算的总流量和含水率与实验设定值也基本吻合,表明该方法具有较高的准确度。To accurately measure and evaluate the oil-water production profile of horizontal wells,a dynamic measurement experiment of oil-water two-phase flow in horizontal wells and numerical simulation were combined to establish a method for measuring the partial phase flow rate of oil-water two-phase stratified flow in horizontal wells.An experimental work was performed in horizontal oil-water two-phase flow simulation well using combination production logging tool including mini-capacitance sensor and mini-spinner.The combination tool provides a recording of holdup and velocity profiles at five different heights of the borehole cross-section.The effect of total flow rate and water-cut on the response of spinner and capacitive sensor at five measured positions were investigated.The capacitance water holdup interpolation imaging algorithm was used to determine the local fluid property and oil-water interface height,and the measured local fluid speed was combined with the numerical simulation result to establish an optimal calculation model for obtaining the partial phase flow rate of the oil-water two-phase stratified flow in the horizontal well.The calculated flow rates of five measured points are basically consistent with the experimental data,the total flow rate and water holdup from calculation are in agreement with the set values in the experiment too,suggesting that the method has high accuracy.
