Production, measurement and control system for electric submersible pump well

Abstract

The invention provides a production, measurement and control system for an electric submersible pump well and relates to the technical field of oil exploitation. The system comprises a remote terminalcontroller, an oil pressure transmitter, a return pressure transmitter, an oil temperature transmitter, a frequency converter and an underground working condition recorder, wherein the frequency converter is connected with an ARM processor in the remote terminal controller and an electric submersible pump; the oil pressure transmitter, the return pressure transmitter and the oil temperature transmitter are connected with the remote terminal controller through an RS232 data interface; the underground working condition recorder is connected with the electric submersible pump and is connected with the remote terminal controller through an RS485 data interface; the oil pressure transmitter, the return pressure transmitter, the oil temperature transmitter and the underground working conditionrecorder transmit the acquired underground data to the ARM processor; and the remote terminal controller is accessed to the IoT (Internet of things) system through an RJ45 network interface so as to report the working condition data of the electric submersible pump. The system provided by the invention can adjust the yield of an oil well in real time and can improve the working energy efficiency of the electric submersible pump.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to an electric submersible pump well production monitoring and control system. Background technique [0002] The measurement data of oil well production is an important reference for dynamic analysis of oilfield development. Whether it is accurate or not directly affects the rational development and deployment of oilfields, and is related to whether oilfield production can develop sustainably. The traditional single-well liquid production measurement method mainly uses a metering separator, which has a large investment, is measured in different periods, and is measured once a day. Intermittent sampling measurement requires manual operation, high labor intensity, low efficiency, and poor real-time data, which cannot truly reflect oil well production. It is impossible to realize real-time online monitoring and remote control of production data. In addition, the existin...

AI Technical Summary

Problems solved by technology

The traditional single well liquid production measurement method mainly adopts the measurement separator device, which requires a large investment, time-period measurement, once a day, and intermittent sampling measurement, which requires manual operation, high labor intensity, low efficiency, poor real-time data, and cannot truly reflect the oil well production. Due to the situation, real-time online monitoring and remote control of production data cannot be realized

In addition, the existing oil exploration monitoring device can only complete the monitoring of production data, and cannot adjust the production process. The electric submersible pump has high work intensity, high energy consumption, easy damage and low work efficiency
