电导示踪相关方法是一种新型的应用于注水井流量测量的新方法。为延缓该方法中NaCl标记溶液的扩散速度,向其加入了聚合物溶液。文章介绍了聚合物溶液电导率特性,加入聚合物前后的标记溶液的阻抗特性的实验研究。实验结果显示,聚合物溶液的电导率随其浓度增加而增大,其电导率特性适合加入到标记溶液中观察;聚合物溶液的加入延缓了NaCl标记溶液的扩散速度,并能增加NaCl溶液测量曲线的波动性,从而更有利于电导传感器检测流动噪声信号。

Conductance correlation method is a new way applying in the flowrate measurement of water injection well.For delaying the diffusion of marking solution and increasing the fluctuation of flowing noise,polymer is added to the NaCl marking solution.The conductance characteristic of polymer solution is analyzed in this paper.The experiment results indicate that the polymer solution conductivity increases along with its concentration.It makes polymer solution suitable to join in mark solution.The impedance characteristic experiment of mark solution added polymer and not is also studied.Results indicate that the diffusion speed of NaCl solution is delayed through adding polymer.The fluctuation curve of marking solution favors the conductance sensors to measure the flowing signals.
