摘　　要：由于水平油水两相流局部流速及局部相含率沿管径方向存在复杂分布,致使其流量及相含率测量非常困难.本文利用伞集流涡轮流量计、电导传感器、过流式电容传感器构成的生产测井组合仪,在水平油水两相流模拟井中开展了动态实验,分析了流动特性及管子角度倾斜对涡轮流量计及含水率传感器响应特性的影响.根据电容及电导传感器在不同总流量及含水率范围的响应分辨特性,分别采用变系数漂移模型及统计模型预测分相流量,发现变系数漂移模型能够自适应调整模型中的流型参数,且对油水两相分相流量具有较高预测精度.Due to the complicated distributions of local velocity and local phase holdup along the radial direction of pipe in horizontal oil-water two phase flow,the total flow rate and phase volume fraction is difficult to be measured.In this study,we carried out dynamic experiment in horizontal oil-water two-phase flow simulation well by using combination production logging tool including turbine flowmeter with petal type concentrating diverter,conductance sensor and flow-passing capacitance sensor.We also investigated the effect of flow characteristic and pipe inclination angle on the response of turbine flowmeter and water-cut meter.According to the resolution capability of the conductance and capacitance sensor in different range of total flow rate and water-cut,we respectively used variable coefficient drift flux model and statistical model to predict the partial phase flow rate.The results show that the variable coefficient drift flux model can self-adaptively adjust the flow pattern parameters and has high prediction accuracy of partial phase flow rate of oil-water two-phase flow.
