Wellhead control system and control method thereof

Abstract

The invention discloses a wellhead control system and a control method thereof. The wellhead control system comprises an intelligent controller, wherein the intelligent controller comprises a centralprocessing unit, and the input end of the central processing unit is electrically connected with the output end of a data acquisition assembly for comprehensively detecting the wellhead; the output end of the central processing unit is electrically connected with an alarm, a ground safety valve, an underground safety valve, an HIPPS high-integrity pressure protection system, an EDS emergency shutdown system, a fusible plug control disc and a hydraulic power unit, and a power generation device supplies power to a charging power supply; and the central processing unit is connected with a monitoring terminal in a signal mode through a wireless communication module so as to facilitate remote control. According to the control method, the wellhead control system is utilized for control, and thuspotential safety hazards can be quickly eliminated; and workers can be advantageously reminded to rapidly withdraw on the site through alarming, and thus asset loss and casualties can be advantageously reduced.

Description

technical field [0001] The invention belongs to the technical field of wellhead control, and in particular relates to a wellhead control system. At the same time, the invention also relates to a control method of the wellhead control system. Background technique [0002] Oil wells are perforations drilled by drilling methods. Generally, after the oil well is drilled into the oil layer, the oil layer casing is lowered, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas, and water layers. The hole gun shoots through the oil layer to form a channel, which is lowered into the oil pipe, and the oil is raised from the bottom of the oil well to the head of the well by a suitable induction method. [0003] Nowadays, more and more attention is paid to the safety performance of the wellhead, but it is generally emphasized that employees carry out safe and standardized operations, and manually de...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, more and more attention is paid to the safety performance of the wellhead, but it is generally emphasized that employees carry out safe and standardized operations, and manually detect whether there is flame generation, whether there is any flammable gas leakage, whether there is leakage in the oil and gas pipeline, and the temperature and humidity of the wellhead. In the event of danger, it is often impossible to quickly transmit the signal, it is difficult to quickly control the closure of the surface safety valve and the downhole safety valve, it is difficult to quickly control the HIPPS high integrity pressure protection system, EDS emergency shutdown system, fusible plug control panel, hydraulic power The unit starts, and there are serious defects, which may easily lead to a large amount of asset loss and casualties
