摘　　要：单井多相计量一直是油田迫切需要突破的问题,科氏力流量计以其较高的质量流量精度,实时提供含水率而广受欢迎。但受限于现场条件,作为含水率及体积流量换算的密度参数并不准确或无法提供。基于此阐述一种在油田现场对单井采出液就地进行油水分离及密度检测的方法。以现场实验获取的单井采出液原油,地层水水密度值作为基于科氏力多相计量撬的参数,进行所采样单井的计量测试实验,与平台现有高精度流量计及取样化验含水率数据比对,相对误差在±5%以内。Single-well multiphase metering has always been an urgent problem in oilfields.Coriolis flowmeters are widely popular for their high mass flow accuracy and real-time water cut.However,due to site conditions,the density parameters used as water content and volume flow conversion are not accurate or available.Based on this,a method for on-site oil-water separation and density detection of single-well produced fluid is expounded.Using the single well produced liquid crude oil and formation water density values obtained from field experiments as the parameters of the multiphase metering skid based on Coriolis force,the measurement test experiment of the sampled single well is carried out,which is consistent with the existing high-precision flowmeter and sampling test of the platform.Comparison of moisture content data,relative error within±5%.
