摘要
水电模拟实验是油田开发物理模拟常用工具,油气藏渗流场中等压线的测定一般采用直接测压法。电压波动会给测定结果带来误差。介绍了用测定等压线的方法,电桥的应用可大大降低电压波动的影响,提高实验精度。
Hydroelectric simulation experiment is a common tool for physical simulation in reservoir development.The measurement of equal-pressure lines in reservoir seepage field generally use direct pressure measuring method.Voltage fluctuation will produce errors to results using this method.This paper introduces a method of measuring equal-pressure lines.The application of bridge can greatly reduce the influence of voltage fluctuation,and improve the accuracy of measurement.
