摘　　要：油田油井动态监测的实质是准确地测量各生产层位的流量和含水率,为此研制了超声波三相流量测试仪。利用该仪器测量油、气、水多相流动的各相流量,通过模拟井动态实验验证了该测井方法的可行性,适用于我国90％以上的生产井,克服了现有国产仪器不能测气和用集流伞下井测量等缺点。The essential of well dynamic monitoring in the oilfield is to accurately measure the flowrate and watercut in each production horizon. Thus an ultrasonic measuring unit of 3 phase flow is developed. The unit is used to measure the flowrates of multi-phase flow of oil, gas and water. The feasibility of the logging method is demonstrated through dynamic experiments in simulation wells, which is ap- propriate to 90% or more of production wells. Thus the shortcomings without measuring gas in available domestic instruments and down-hole measuring with collecting umbrella are overcome.
