Abstract
The invention relates to a remote electric pneumatic control system. The system is characterized in that: a programmable logic controller (PLC), a cylinder and an electromagnetic reversing valve are arranged in a console; a magnetic switch is arranged outside the cylinder; a single outlet rod arranged on the cylinder is connected with a reversing valve rod of a three-station four-way liquid turning valve through a lever; and the electromagnetic reversing valve is connected with the cylinder through an air guide pipe. In a driller station and an auxiliary driller station, the PLC instructs the electromagnetic reversing valve to change the flow direction of a power gas through a wired cable or a wireless transmission device so as to change the movement direction of a piston in the cylinder, and the direction of controlling the hydraulic power of a blowout preventer gate plate is changed through the three-station four-way liquid turning valve. The system has the advantages of safe air pressure pipelines, high automation degree, simplicity and convenience in operation and control, strong flexibility, high sensitivity and the like.
Description
Technical field
The present invention relates to the moving control system of a kind of long distance electric, be used for controlling the Long-distance Control of the 3-position 4-way liquid rotary valve oil circuit of ground preventer, belong to oilfield machinery remote control technology field.
Background technology
In China's oil drilling well remote control, widely used 3-position 4-way liquid rotary valve, the conventional method of its Long-distance Control is: change airflow direction by the 3-position 4-way cyclostrophic valve in driller station or the auxiliary driller station, and the compressed air delivery that will change direction through the air hose cable makes cylinder reciprocating in the cylinder of remote console.Drive the 3-position 4-way liquid rotary valve transposition of ground preventer switch again by the single rod in the cylinder, realize the conversion of oil circuit.Because this transfer process is a Long-distance Control, distance between driller station or auxiliary driller station and the field control station is at least more than 50M, air pressure transmission therebetween must rely on the air hose cable as passage, and this passage often is exposed to without any the open-air ground of covering.This is for the oil field of northern cold zone, and the air hose cable bursting by freezing phenomenon in its ground preventer remote control just seems quite serious.The consequence of being brought is that the safety of well head blowout prevention can not get guaranteeing.In addition, this traditional long-range control method is to utilize the 3-position 4-way cyclostrophic valve of changing manually in driller station or the auxiliary driller station to change airflow direction.Thereby its automaticity is poor, the Long-distance Control trouble.Therefore, in oil drilling ground preventer remote control, design a kind of electro-pneumatic and compensate mutually, and the control system of automaticity height, Long-distance Control simple and sensitive, belong to the task of top priority in fact.
Summary of the invention
For the Long-distance Control that realizes ground preventer is opened and closed, the present invention proposes the moving control system of a kind of long distance electric.
To achieve these goals, the present invention implements by the following technical solutions: it is made of auxiliary driller station three parts in the driller station on the console that is arranged on well head, the derrick, the far distance controlled chamber.Console is made up of 3-position 4-way liquid rotary valve, cylinder, magnetic switch, solenoid operated directional valve, PLC programmable logic controller etc.; Driller station is made up of touch-screen, button indicator lamp etc.; Auxiliary driller station is made up of button indicator lamp etc.It is characterized in that being provided with in the console PLC programmable logic controller, cylinder, solenoid operated directional valve; The described cylinder peripheral hardware switch that is magnetic, single rod that described cylinder is provided with is connected by lever and 3-position 4-way liquid rotary valve commutation valve rod; Described solenoid operated directional valve is connected with cylinder by wireway.The signal of telecommunication of described driller station, auxiliary driller station, solenoid operated directional valve, magnetic switch is connected with the PLC programmable logic controller by wire cable or radio transmitting device.
The present invention has pneumatic circuit safety, automaticity height, easy, the advantages such as flexibility is strong, sensitivity height of operation control.
Description of drawings
Accompanying drawing 1 is the structural principle schematic diagram of utility model.
In accompanying drawing 1: 1 console, 2 driller stations, 3 auxiliary driller stations, 4 button indicator lamps, 5 touch-screens, 6PLC programmable logic controller, 7 solenoid operated directional valves, 8 cylinders, 9 magnetic switchs, 10 3-position 4-way liquid rotary valves.
The specific embodiment
As shown in Figure 1, on the two ends desired location of cylinder 5 outer walls, be respectively charged into magnetic switch 6; By lever the single rod in the cylinder 5 is connected with valve rod on the 3-position 4-way liquid rotary valve 10; With the wireway cable source of the gas, solenoid operated directional valve 4, cylinder 5 are connected into pneumatic circuit.The signal of telecommunication of driller station 2, auxiliary driller station 3, solenoid operated directional valve 7, magnetic switch 9 is connected with PLC programmable logic controller 6 by wire cable or radio transmitting device.When the flashboard in the preventer of ground need cut out: the staff can send instruction to PLC programmable logic controller 6 by the button on driller station 2, the auxiliary driller station 3 (the also remote controller that can establish by other), this moment, PLC programmable logic controller 6 instruction solenoid operated directional valves 7 entered the right chamber of cylinder 8 with source of the gas from the P solenoid operated directional valve 7 that entered the mouth into, single rod in the cylinder 8 moves right to left movement and by the commutation valve rod in the lever drives 3-position 4-way liquid rotary valve 10 and realizes closing the open-minded of flashboard oil circuit, and the flashboard that promotes in the preventer cuts out.Meanwhile the single rod piston in the cylinder 8 moves to left desired location, the magnetic switch 9 that cylinder 8 outer left sides are provided with obtains a pulse signal and feeds back to PLC programmable logic controller 6, and the result after PLC programmable logic controller 6 is handled signal is presented on the display of touch-screen 5, button indicator lamp 4.
When the flashboard in the preventer of ground need be opened: the staff can send instruction to PLC programmable logic controller 6 by the button on driller station 2, the auxiliary driller station 3 (the also remote controller that can establish by other), this moment, PLC programmable logic controller 6 instruction solenoid operated directional valves 7 entered the left chamber of cylinder 8 with source of the gas from the P solenoid operated directional valve 7 that entered the mouth into, single rod in the cylinder 8 moves right and moves left by the commutation valve rod in the lever drives 3-position 4-way liquid rotary valve 10 realize to open the open-minded of flashboard oil circuit, and the flashboard that promotes in the preventer is opened.Meanwhile the single rod piston in the cylinder 8 moves to right desired location, the magnetic switch 9 that cylinder 8 external right sides are provided with obtains a pulse signal and feeds back to PLC programmable logic controller 6, and the result after PLC programmable logic controller 6 is handled signal is presented on the display of touch-screen 5, button indicator lamp 4.
When ram block does not move, the meta under PLC programmable logic controller 6 instruction solenoid operated directional valves 7 are in the normal state, the left and right chamber in the cylinder 8 communicates with atmosphere 0 interface.
Among the present invention, the constructor also can manually control 3-position 4-way liquid rotary valve 10 at the scene, promptly realizes the manual open and close to flashboard in the ground preventer.
The staff can realize control on duty to ground preventer by the cooperation of auxiliary driller station 3 and specific remote control.
