摘　　要：在油井中,因油水滑脱的存在,使得持水率大于含水率。因为仪器所测量到的是持水率,所以需要通过模型再把持水率转换成含水率。通过建立油水在模拟井中的流动模型,并对其进行数值仿真,获得了油水滑脱规律。从实验上证明提高油水的流速,可以减少滑脱现象对持水率的影响,保证了含水率的准确测量。In oil wells, water-holdup measured by tool is higher than water-cut due to the surge of oil and water. Considering that only water-holdup can be directly measured by tool, it is necessary to transform water-holdup into water-cut by model. In this paper, the flowage model of oil and water is built up. Several rules of oil and water surge are obtained by simulating some wells based on the above model. From the test, it is shown that effect of surge on water-holdup can be weakened by increasing the flow velocity of oil and water, which assures the accuracy of water-holdup measurement.
