摘　　要：针对低产水平井内流体的流动特征,在剖析阵列持水率仪器测井原理及探头响应情况的基础上,借助多相流动模拟实验装置开展模拟实验研究,利用实验数据对比研究平均值法、分层界面法、成像法和积分法这4种适用于低产水平井油-水两相流的持水率计算方法。研究结果表明,成像法在低流量含水率较低时与实验标尺刻度持水率值之间误差较小并具有较高的准确度,而当含水率升高时分层界面法的误差约为5%,表明分层界面法在高含水情况下具有较好的适用性。Combined with fluid flow characteristics in low-yield horizontal wells,based on the analysis of the logging principle of the array water holding rate instrument and the response of the probe,the array capacitance water holding rate instrument is used to carry out simulation experiments with the help of a multiphase flow simulation experimental device.The experimental data are used to compare and study the four methods for calculating the holding rate of oil and water in low-level horizontal wells,including the average method,layered interface method,imaging method,and integration method.The research results show that the imaging method has a small error between the low water content of the low flow rate and the water holding value of the experimental scale and has a high accuracy.When the water content increases,the error of the layered interface method is about 5%,indicating that the method has good applicability under high water content.
