The blowout preventer remote control platform comprises a blowout preventer remote control platform and a workover rig braking device, wherein an energy accumulator, a flashboard control valve and an operating rod are arranged on the blowout preventer remote control platform, the workover rig braking device comprises a brake control valve, a roller, a brake braking assembly and a pneumatic clutch, and a double H valve is further arranged on the blowout preventer remote control platform. Through install two H valves additional on preventer remote control platform, the control system of well workover car and preventer is correlated with by two H valves, realizes the coordinated control of well workover car and preventer, implements remote control on preventer remote control platform, effectively avoids appearing because of misoperation with the condition that the preventer flashboard was pulled out badly, makes the construction safer.
Description
Technical Field
The utility model relates to a petroleum equipment technical field specifically is a blowout preventer and workover car interlock.
Background
At present, in the oil and gas industry, maintenance operation is often required to be carried out on oil, gas and water wells. When maintenance operation is carried out, the blowout preventer flashboard in an oil well needs to be opened, and pipe and rod descending operation is carried out by hoisting the blowout preventer flashboard in a well through the cooperation of a workover rig. The existing blowout preventer ram does not have effective protective equipment, so that accidents that the blowout preventer ram is pulled out and an oil pipe falls into a well due to misoperation often occur, great influence is caused on normal maintenance and production operation, and a large amount of manpower and material resources are wasted; at present, the risk of misoperation can only be avoided by the care of workers, and no effective device can realize the linkage control of the blowout preventer and the workover rig.
SUMMERY OF THE UTILITY MODEL
The technique that exists is not enough to the aforesaid, the utility model aims at providing a preventer and workover car interlock through install two H valves additional on preventer remote control platform, is correlated with the control system of workover car and preventer by two H valves, realizes the coordinated control of workover car and preventer, implements remote control on preventer remote control platform, effectively avoids appearing because of misoperation with the condition that the preventer flashboard was pulled bad, makes the construction safer.
In order to solve the technical problem, the utility model adopts the following technical scheme:
a blowout preventer and workover rig interlocking device comprises a blowout preventer remote control console and a workover rig braking device, wherein an energy accumulator, a flashboard control valve and an operating rod are arranged on the blowout preventer remote control console; and the output end of the double H valve is communicated with the input end of the brake control valve.
The beneficial effects of the utility model reside in that: this design is through installing two H valves additional on preventer remote control platform, and the control system of well workover car and preventer is correlated by two H valves, realizes the coordinated control of well workover car and preventer, implements remote control on preventer remote control platform, effectively avoids drawing the condition appearance of damaging the preventer flashboard because of misoperation, makes the construction safer.
