电导式相关流量计应用于油井井下流量测量

摘要

本文提出了一种新型的电导相关流量计，其敏感元件采用两个电导传感器，该流量计能够应用于高含水油井的油水两相流流量测量。在多相流动实验装置上进行的实验表明，该流量计测量的流速范围宽,线性好。该流量计已经在大庆油田进行现场试验。使用该流量计在井下测量的油水的总流量与地面计量结果对比良好。%A new type of conductance cross correlation flowmeter based ontwo conductance sensors has been designed to measure the velocity of oil/water two-phase flow in a borehole. This flowmeter is capable of measuring the flowrate in a production well with high water cut . Experiment results carried out in a multiphase flow loop facility demonstrated that the flow velocity measuring range is from 0.0368 to 3.68m/s, and the relative deviation is 2.3%. Field tests have been performed with the flowmeter in Daqing oilfield. The total flowrates measured with the flowmeter in the well are very closed to the flowrates metered at surface
