Research on Hydraulic Reciprocating Gas-Liquid Mixed Transport Boosting Device and Intelligent Control System

The hydraulic reciprocating gas-liquid mixed flow boosting device is an important boosting equipment for optimizing the operation of gas fields. This device can be used to increase the pressure at the wellhead and transport oil and gas. At the same time, with the help of an intelligent control system, it can achieve constant pressure control for gas-liquid mixed transmission and predict pipeline holdup. Based on the working principle of the liquid driven reciprocating supercharger, the fuzzy PID control algorithm and the liquid holdup prediction model are established and simulated for application, which is beneficial for the reliable and stable operation of the device. The use of fuzzy PID control algorithm and accurate prediction of pipeline holdup can improve the efficiency of natural gas well production in the later stage and achieve stable and increased production in the later stage of natural gas well development.
