全井眼电导含水率计在油水两相流中动态实验

对全井眼电导含水率计的结构和测量原理进行了简要介绍.该含水率计在油水两相流下进行了多次重复实验,并对实验结果进行了处理与分析,给出了该含水率计在不同流量下和不同含水率下的误差分布情况.结果表明,在实验流量范围内,10 m3/d时全井眼电导含水率计的测量含水率误差最大,且含水率测量误差随流量增大而减小;30 m3/d以上时测量误差在±5.5%以内.结合滑脱效应和电场分布特性分析了造成误差分布特点的原因.

Dynamic Experiment of The Full Borehole Conductance Water-cut Meter in Oil-water Two Phase Flow

The structure and measuring principle of the full borehole conductance water-cut meter is briefly introduced.The experiments are carried out in oil-water two-phase flow.The experimental results are processed and the repeated experimental results for many times are given.The repeatability of the water-cut meter and error distribution under the condition of different flow rates and water cut are analyzed.The results show that within the range of the experimental flowrates,the error of the meter is the biggest...
