水力活塞泵是一种依靠液体压力传递能量的抽油系统。多年来对井下泵工况仍停留在人工观察压力表的压力变化而凭借经验进行诊断的水平上。由于各人经验的相互差异，增大了分析、诊断结果的误差，导致盲目起换泵工作量的增加而影响产油量。本文在阐述了水力活塞泵运动规律的基础上，采用便携式计算机，在地面采集和记录水力活塞泵生产井井口动力液压力和流量随时间的变化规律，对比典型工况模版，确定井下果工作状况，从而提高了水力活塞泵生产井的管理水平。
Hydraulic piston pump is a pumping system that relies on liquid pressure to transfer energy. Over the years the underground pump operating conditions still remain in the manual observation of pressure changes in pressure gauges by experience to diagnose the level. Due to the mutual differences of experience, the errors of analysis and diagnosis results are increased, resulting in blindly changing the workload of the pump and affecting the oil yield. Based on the description of the movement rule of the hydraulic piston pump, a portable computer is used to collect and record the dynamic pressure and flow rate of the hydraulic piston pump at the wellhead on the ground and compare with the typical working condition template to determine the working condition , Thereby improving the management of hydraulic piston pump production wells.
