Abstract
The invention discloses a remote hydraulic well opening and closing device for oil-gas well mouth emergency rescue. The remote hydraulic well opening and closing device for the oil-gas well mouth emergency rescue is designed for performing quick, safe and effective emergent shut of a burning well mouth in an oil-gas well accident. The remote hydraulic well opening and closing device for the oil-gas well mouth emergency rescue is formed by connecting an oil tank, a hydraulic pump, an overflow valve, a switching valve, and a pressure regulating valve, wherein a hydraulic power station is connected with a hydraulic gerotor motor through hydraulic pipelines, a balancing bar is fixed on an operation vehicle through hinge pins and a holder, the hydraulic gerotor motor is fixed on the balancing bar, the output end of the hydraulic gerotor motor is connected with a bevel gear set through a transmission shaft, and the output end of the bevel gear set is connected with a wheel claw. According to the remote hydraulic well opening and closing device for the oil-gas well mouth emergency rescue, increased mechanical torque can be directly exerted on a gate of an accident well mouth through remotely electric control, the emergency shut of the gate is achieved in the first time, life safety of field staffs is guaranteed, and the environment is prevented from being seriously polluted. The remote hydraulic well opening and closing device for the oil-gas well mouth emergency rescue can be widely applied to the opening and closing operation of manually operated actuating mechanisms of large-sized hydraulic ball valves in emergency circumstances.
Description
Technical field
The present invention relates to a kind of Remote Hydraulic of speedily carrying out rescue work for oil and gas wellhead and open well shutdown appts, belong to petroleum gas well head emergency technique field.
Background technology
Oil/gas Well well head leaks not only serious threat people's the life security of catching fire, and contaminated environment is serious, if dealt with improperly, consequence is hardly imaginable, and key measure is to strive for robbing and closing shaft collar (particularly 1# master control valve) in the very first time.The existing way in each oil field is to rely on the personnel of speedily carrying out rescue work to wear fire proximity suit to rush in the scene of a fire, with common pipe wrench closed-in well port strobe.Dodge the reasons such as quick-fried because borehole pressure is large, valve core rod easily flies out and secondary may occur, the danger that the personnel that speedily carry out rescue work face at well head is very big.Meanwhile, the larger pressure reduction of valve upstream and downstream has increased the moment of torsion of valve-off, even if two people are also difficult to pull gate.
Summary of the invention
The object of the present invention is to provide a kind of Remote Hydraulic of speedily carrying out rescue work for oil and gas wellhead to open well shutdown appts, it can catch fire that well head carries out rapidly to Oil/gas Well accident, safety and effectively rob pass.
Concrete technical scheme of the present invention is as follows:
Hydraulic power station is connected and composed by fuel tank, hydraulic pump, overflow valve, switch valve and pressure regulator valve; Hydraulic power station connects hydraulic pressure gerotor motor by hydraulic line; Balancing pole is fixed on work car by swivel pin and The Cloud Terrace; Hydraulic gerotor motor is fixed on balancing pole, and its output is by power transmission shaft Connectable umbrella gear train, and bevel gear group output connects tire.
The present invention can directly act on the mechanical torque of increase the gate of accident well head by remote electric control, the gate of realizing in the very first time is robbed pass, and the personnel's that can keep the scene intact life security, avoids environment to be heavily polluted.This device can be widely used in the switching operations of the large-scale ball valve manual executing agency in emergency circumstances of surging.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the Remote Hydraulic of speedily carrying out rescue work for oil and gas wellhead is opened well shutdown appts.
Fig. 2 is the connection diagram of hydraulic power station equipment.
The specific embodiment
With reference to Fig. 1 and 2, embodiments of the invention are further illustrated:
Embodiment:
The present invention is made up of hydraulic power station 1, hydraulic line 2, hydraulic gerotor motor 3, power transmission shaft 4, bevel gear group 5, tire 6, The Cloud Terrace 7, work car 8, swivel pin 9 and balancing pole 10:
Hydraulic power station 1 is connected and composed by fuel tank 11, hydraulic pump 12, overflow valve 13, switch valve 14 and pressure regulator valve 15.Hydraulic power station 1 connects hydraulic pressure gerotor motor 3 by hydraulic line 2.Balancing pole 10 is fixed on work car 8 by swivel pin 9 and The Cloud Terrace 7.Hydraulic gerotor motor 3 is fixed on balancing pole 10, and its output is by power transmission shaft 4 Connectable umbrella gear trains 5, and bevel gear group 5 outputs connect tire 6.
According to actual needs, hydraulic power station 1 can regulate moment of torsion by pressure regulator valve 15, if moment of torsion exceeds design, is protected by overflow valve 13 releasing pressure automaticallies.Switch valve 14 adopts spring 3-position 4-way valve arrangement, by the direct far-end control of the personnel of speedily carrying out rescue work.Outputting torsion is passed to bevel gear group 5 and tire 6 by hydraulic gerotor motor 3, to increase steering torque, realizes working distal tip and turn to, and also can avoid the spool risk causing that flies out simultaneously.For fear of temperatures involved, hydraulic line 2 adopts high temperature resistant model, and hydraulic gerotor motor 3 adopts inflammable material parcel.Balancing pole 10 is used to working end counterweight, and it can horizontally rotate and swing up and down, and tire 6 is aimed to valve spider handle 16 like a cork.Balancing pole 10 length 2m, can need to decide voluntarily according to scene, carry and Assembling so that speedily carry out rescue work.Tire 6, by inside and outside four directions and pin Connectable umbrella gear train 5, if shaft collar is provided with handwheel, adopts tire working end, if there is no handwheel (handwheel is lost or damaged), adopts six square socket working ends.
The course of work of the present invention is as follows:
When oil and gas wellhead occurs when leaking and catching fire, the personnel that speedily carry out rescue work carry the each parts of this emergency device and enter scene of the accident weather and carry out rapid-assembling.Lineup is connected in bevel gear group 5 outputs with pin by tire 6, and balancing pole 10, hydraulic gerotor motor 3 and bevel gear group 5 are connected, more then 10 of balancing poles are swung to balancing pole 10 on The Cloud Terrace 7, tire 6 is docked on the valve spider handle 16 of well head.Meanwhile, hydraulic power station 1 is pushed scene by another lineup, is connected hydraulic power station 1 and hydraulic motor 3 with snap joint with hydraulic line 2.Operator stands on operating desk at a distance, by observing front a group of people's the signal operating switch valve 14 of waving, starts hydraulic power station 1.Power is delivered to bevel gear group 5 and tire 6 through hydraulic gerotor motor 3 and power transmission shaft 4, and tire 6 pins valve spider handle 16, and drives valve spider handle 16 to rotate with the reinforcement moment of torsion of its acquisition, rapidly, safety and effectively well head main control valve door out of control being closed.
At the beginning of 2011, in Soviet Union Sulige gas field natural gas well site, carry out the natural gas well and leak the emergency repair combat exercise of catching fire, christmas tree model KQ-65/70, comburant is natural gas and condensate mixture in well.After device assembles, by originally opening well shutdown appts working end easily to upper lock gate, then remove safety zone.The rear personnel of speedily carrying out rescue work start emergency device, only more than the 20 second used time, just close well head 1# valve rapidly, and big fire is extinguished immediately, the success of speedily carrying out rescue work.
