Problems solved by technology

Pressing the control button may generate electric sparks, which cannot be explosion-proof; the two remote control devices are connected to the accumulator device through multiple air pressure pipes, and the connecting pipes are relatively complicated; at the same time, through the air pressure remote control, when the air pipe is long, its The lag time of the control is long; in addition, it is greatly affected by the ambient temperature. When the temperature is lower than zero, the air pipe may be blocked due to condensation of water vapor, resulting in control failure

Abstract

The invention discloses a ground blowout preventer controller, comprising: energy storer, remote controller and auxiliary remote controller, where the remote controller and the auxiliary remote controller are equipped with touch screens, LCD screen is separated from the touch screen and externally equipped with the touch screen of toughened glass, the upper and lower directions of the touch screen are installed with multiple tube groups of infrared transmitting and receiving tubes, the touch screen is connected with PC, the signals received by the touch screen is transmitted to the PC, and the PC is connected with a valve controller of the energy storer and sends instructions to the valve controller to control its action. And the invention has good explosion prevention performance; besides, the touch screen of toughened glass separates the LCD screen from the outside so that the LCD screen can adapt to lower environmental temperature, resist impact and be unafraid against scraping.

Description

technical field [0001] The invention relates to a pressure control device for oil and gas wells, in particular to a control device for surface blowout preventers of oil and gas wells. technical background [0002] In drilling operations in the fields of petroleum, geology, mining, etc., when the pressure of the liquid column in the drill string is lower than the pressure of the formation fluid, there is a danger of well kick or even blowout. In order to prevent well kicks and blowouts, blowout preventers need to be installed on the ground at the wellhead, and the blowout preventers are controlled to be closed by the blowout preventer control device to prevent well kicks and blowouts. The existing ground blowout preventer control device is generally composed of an accumulator device, a remote control device and an auxiliary remote control device. The control button on the device is used to control the air pressure in the air pressure pipe to drive the valve action on the acc...
