原油生产过程中需测量各种参量，如含水、温度、流量、密度、压力等，而这些参量中最重要的是含水和流量，因为只有知道了总液量和油中的含水率，才能知道总油量。目前流量计量已基本过关，但含水计量一直是令各油田管理部门头疼的问题。虽然各行各业的科技工作者通过不懈地努 Crude oil production processes need to measure a variety of parameters, such as water, temperature, flow, density, pressure, etc., and the most important of these parameters is water and flow, because only know the total fluid volume and oil moisture content, to know Total oil. At present traffic measurement has basically passed, but water metering has always been a headache for oilfield management departments. Although science and technology workers in all walks of life through unremitting efforts
