Embedded Monitoring System of Progressing Cavity Pump Operating Conditions

Abstract:

The monitoring system for progressing cavity pump operating conditions based on dual-microcomputer is developed to fit the electronic parameters measurement characteristic and requirement of progressing cavity pump. By measuring the electronic parameters of progressing cavity pump driving motor and combining the internal losses of electrical motor, the torque and speed of progressing cavity pump polished rod are calculated accurately, to make correct decision for the oil wells working condition. Using the modular design method, the acquisition, storage, human-computer interaction and other necessary hardware is presented. The program flow charts of host-slave is designed respectively, Parameters calibration and communication module are mainly elaborated, in the meanwhile, computer’s data processing and fault diagnosis software are designed. The designed system has been successfully applied in oilfield, realizing the monitoring of screw pump’s working condition,ensuring the efficient operation of oil production system.
