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
The present invention relates to a kind of oil gas well pressure control device, particularly a kind of oil gas well control system of ground preventer.
Technical background
In the drillng operation in fields such as oil, geology, mining industry, when the head of liquid in the drill string is lower than formation fluid pressure, the danger that well kick even blowout take place is arranged.In order to prevent the generation of well kick and blowout, preventer need be installed in the ground of well head, by closing to prevent well kick and blowout of blowout preventing control apparatus control preventer.Existing control system of ground preventer, generally form by accumulator device, remote control and auxiliary remote control, join by many pneumatic tubes between its remote control and auxiliary remote control and the accumulator device, by pushing the control button on two remote controls, control air pressure in the pneumatic tube driving the valve event on the accumulator device, thereby drive the blowout prevention valve action.It pushes control button may have the electric spark generation, can not be explosion-proof; Be connected by many pneumatic tubes between two remote controls and the accumulator device, connecting line is comparatively complicated; Simultaneously, by the air pressure remote control, when tracheae was longer, the lag time of its control was longer; In addition, it is subjected to the influence of environment temperature bigger, and when temperature was lower than zero degree, tracheae may be gambled plug because of condensation of moisture, causes Control Failure.
Summary of the invention
The object of the present invention is to provide a kind of control hysteresis time short, not influenced by ambient temperature, safe and reliable, easy to operate, and control system of ground preventer that can be explosion-proof, low temperature resistant.
Control system of ground preventer of the present invention, comprise the accumulator device, remote control and auxiliary remote control, on remote control and the auxiliary remote control touch-screen is arranged all, the LCD Panel of touch-screen separates with touch screen, LCD Panel is installed the touch screen that tempered glass is made outward, the above-below direction of touch screen and left and right directions all are equipped with a plurality of pipe groups of being made up of infrared emission tube and infrared receiver tube, touch-screen is electrically connected with PC, the signal that touch-screen receives is passed to PC, PC is electrically connected with the valve positioner of accumulator device again, carries instruction to give valve positioner, controls its action.
Control system of ground preventer of the present invention, during work, infrared light beam between infrared emission tube and infrared receiver tube forms grating on touch screen, when operator point touches the touch screen that tempered glass makes, just can break beam, make corresponding infrared receiver tube can't normally receive light, thereby determine the position that point touches, this moment, touch-screen sent a signal to PC, send a signal to the valve positioner of accumulator device again by PC, the switching of the valve of control accumulator device, thus realization is to the control of preventer.Its remote control and auxiliary remote control are electrically connected with PC, connect by cables such as power line, holding wires to get final product, and its line is simple, light, signal transmits soon, and time-delay is short; And the length of cable can be very long, and remote control distance can be farther.In addition,, also be not subjected to the influence of temperature, do not exist the low temperature condensation of moisture when using pneumatic tube control to gamble the phenomenon of filling in tracheae and causing Control Failure by the cable transfer control signal, thus safer, reliable.Simultaneously, remote control uses touch-screen to operate, and its operation is simple more, convenient.In addition, touch-screen has outward LCD Panel and the extraneous touch screen of being made by tempered glass that separates, during operation, operating personnel only directly operate on tempered glass, and need not contact LCD Panel, thereby do not have the induced-current generation, even the outside is full of flammable explosive gas such as oil, natural gas, also can not set off an explosion, anti-riot performance is good.Simultaneously, touch-screen is separated by the tempered glass and the external world, and it can adapt to lower environment temperature.In addition, tempered glass can also the better protection LCD Panel, can prevent that it from being clashed into and scratch.
Description of drawings
Fig. 1 is a kind of schematic diagram of control system of ground preventer.
The specific embodiment
Embodiment 1, as Fig. 1, a kind of control system of ground preventer, comprise accumulator device 1, remote control 2 and auxiliary remote control 3, on remote control 2 and the auxiliary remote control 3 touch-screen 4 is arranged all, the LCD Panel 4a of touch-screen 4 and touch screen 4b separate, LCD Panel 4a installs the touch screen 4b that tempered glass is made outward, the above-below direction of touch screen 4b and left and right directions all are equipped with a plurality of pipe groups of being made up of infrared emission tube 4c and infrared receiver tube 4d, touch-screen 4 all is connected with PC5 by cable, and PC5 is connected with the valve positioner 6 of accumulator device 1 by cable again.When the needs preventer moves, point touches touch screen curtain 4b, stop infrared emission tube 4c emitted light beams, the infrared light beam that infrared receiver tube 4d is received changes, thereby send a signal to PC5, send a signal to the valve positioner 6 of accumulator device by PC5, the valve 7 of control accumulator device opens and closes, and realizes the control to preventer.Its remote control 2 is connected with PC5 by cable with auxiliary remote control 3, and its line is simple, light, signal transmits soon, and time-delay is short; And the length of cable can be very long, and its remote control distance is farther.In addition,, also be not subjected to the influence of temperature, do not exist the low temperature condensation of moisture when using pneumatic tube control to gamble the phenomenon of filling in tracheae and causing Control Failure by the cable transfer control signal, thus safer, reliable.Simultaneously, remote control uses touch-screen 4 to operate, and its operation is simple more, convenient.In addition, the touch screen 4b of touch-screen 4 is made by tempered glass, during operation, does not have induced-current and produces, even the outside is full of flammable explosive gas such as oil, natural gas, also can not set off an explosion, and anti-riot performance is good.In addition, touch screen 4b is made by tempered glass, and it separates the LCD Panel 4a and the external world, thereby can adapt to lower environment temperature; Simultaneously, the touch screen 4b that tempered glass is made can also better protection touch-screen 4, can prevent that touch-screen 4 is by scratch and bump.
In order to guarantee that above-mentioned blowout preventing control apparatus still can normally use when cutting off the power supply, PC adopts ups power, and remote control and auxiliary remote control adopt battery and charger to power.When supply line had a power failure, ups power can be powered to PC, and battery can be to remote control and the power supply of auxiliary remote control.Therefore, even supply line's outage, preventer also can operate as normal.
