A solar power supply remote intelligent control constant pressure deflation device

Abstract

A solar power supply remote intelligent control constant pressure deflation device, which relates to an electric submersible pump well casing pressure adjustment device in the oil (gas) wellhead of an oil and gas field, which consists of a solar power supply system (on-site), a remote intelligent remote control system, a constant pressure deflation The system (on-site valve body) consists of three parts. The device is installed on the outlet manifold of the wellhead casing, and a solar power supply system is installed on the device. The solar power supply system is composed of solar cells, controllers, battery packs, DC / It consists of an AC inverter, the solar battery is connected to the controller, and the controller is connected to the DC / AC inverter and the battery pack respectively. A solar power supply remote intelligent control constant pressure deflation device, which uses an intelligent control system to realize remote intelligent control of the deflation device through the network, and uses solar power to provide electric energy for the deflation device of the casing pressure of the electric submersible pump well, thereby Realize real-time monitoring of the casing pressure of the constant pressure deflation device, precisely control the discharge of casing gas, and achieve remote intelligent control.

Description

technical field [0001] The invention relates to an electric submersible pump well casing pressure regulating device in an oil (gas) wellhead in an oil and gas field, in particular to a solar power source remote intelligent control constant pressure deflation device. Background technique [0002] Since my country's reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation, independent innovation" has become the mainstream of my country's current industrial development. my country's industry is gradually developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. In the oil (gas) wellhead, the casing gas is discharged into the oil (gas) manifold through the gas release device to control the reasonable submergence of the suction inlet of the electric pump, prevent the occurrence of the air lock phenomenon of the electric pump for oil production, and at the same time control the Casing gas emission...

AI Technical Summary

Problems solved by technology

The commonly used deflation device adopts manual pressure regulation, which is slow in response and inaccurate in pressure regulation

In the process of oil (gas) production in oil and gas fields, working devices often have occasions where there is no AC power at the work site or it is difficult to obtain power, which brings inconvenience to the power supply of the equipment
