摘要
利用潜油泵电机的电力线传送测量信号是一种新型油田井下压力测量方法。由于电力载波数字信号,测量精度高,优于目前国内油田广泛使用的滑线电阻式油田井下压力测量仪。此方法不仅适用于油田,而且可用于使用同一电力变压器供电的任何领域。
A new pressure measuring method applying in deep oil-well is as follows.Using the electric power line digital carrier,measured signal can be transmitted by the oil-pump's power line and high quality signal can be getten.The new method can be used not only in deep oil-well measurment but also in many other fields.
