A blowout preventer is arranged on the trailer of a pipe column device under the action of a horizontal telescoping mechanism composed of a square hole sleeve, a guide post and a telescoping oil cylinder, the blowout preventer can extend out of the trailer; two oil passages of the tubular column and the blowout preventer form a bridge hydraulic extending passage via a one-way valve, a hydraulic one-way valve, a two-place two-way valve; an auxiliary fluid cylinder and a clutch are sheathed on the shaft of the fluid cylinder of the winding machine of the tubular column device; the shaft end of a drum is provided with an auxiliary motor and the clutch; the working machine integrates the tubular column device and the blowout preventer organically, increasing the performance and the strain capacity of the machine, and having definite positive role for oil production.
Description
The utility model belongs to the oilfield machinery class.
Blowout hookup and tubing string running and pulling device are the indispensable equipment of field produces, present tubing string running and pulling device is that a hoist engine is installed on trailer, by hydraulic jack suspension rod is risen and fallen, the wire rope of hoist engine by suspension rod supporting with drop hanger to the tubing string operation of rising and falling, job content is more single.And existing by top rail, slips oil cylinder, traveling slip, stationary slip, self-styled, stablize the blowout hookup that beam, atmospheric valve, connecting flange, pressurization oil cylinder, safety slip, half envelope, full envelope, lower transverse beam, base flange constitute, job content is also more single.
The purpose of this utility model is: increase the operation function of tubing string running and pulling device, make it also to have the effect of the blowout of preventing, improve the efficient of field produces.
The technical solution of the utility model is: blowout hookup is displaced on the tubing string running and pulling device; On the trailer of tubing string running and pulling device, fix a horizontal telescoping mechanism, under the effect of this mechanism, blowout hookup can be stretched out the trailer alignment well head, hoist engine drop hanger by the tubing string running and pulling device is seated to it on well head, and the time spent can not be retracted into blowout hookup on the trailer; Increase by one and pay cylinder and clutch on the hoist engine drum shaft of tubing string running and pulling device, hydraulic pressure of device is paid motor and clutch on the cylinder axle head; Two hydraulic circuits of tubing string running and pulling device and blowout hookup adopt the bridge-type hydraulic circuit, and two oil circuits can be supported mutually, improve the fan-out capability of hydraulic system.
Fig. 1 is a structural representation of the present utility model; Fig. 2 is a vertical view.
2 is trailers of tubing string running and pulling device among the figure, hoist engine 3 is housed on the trailer, and motor 1 makes hydraulic pressure master motor 13 fuel feeding of oil pump 15 to hoist engine cylinder axle head, orders about drum shaft and rotates, wire rope on the hoist engine 3 plays the lower tubular column operation by suspension rod 9 supportings with drop hanger 8; Suspension rod 9 can be rolled over to fall to keeping flat and prop operation by supporting oil cylinder 10, and square hole cover 4 and guide pillar 5 are newly-installed horizontal telescoping mechanisms; Guide pillar 5 can overlap in 4 at square hole under the effect of telescopic oil cylinder and move horizontally, on the front end of guide pillar 5, fix a bearing, blowout hookup 6 is located on the bearing, when needs are sealed well head 7, oil cylinder is released guide pillar 5, makes blowout hookup 6 align well head 7, and hoist engine 3 usefulness drop hangers 8 are sling blowout hookup 6, guide pillar 5 withdrawals make 6 to be seated on the well head 7.12 is supports among the figure, about each one, it is supporting hoist engine 3; The 13rd, hydraulic pressure master motor (original motor), it connects with hoist engine cylinder 16 by shaft coupling, and master rotor 11 is rotated.The have cylinder of paying 19 and interposed clutch 20 and the hydraulic pressure that increase newly are paid motor 18 and clutch 17; Pay cylinder 19 skies and be enclosed within on the drum shaft 16, interposed clutch 20 is fixed on the drum shaft 16, rotates and can endwisely slip with axle; It with pay the cylinder end face and constitute a separation and reunion, in conjunction with the time can make and pay cylinder 19 and rotate simultaneously with axle, pay cylinder 19 during disengagement and stop operating; Has only a cylinder (master rotor) on the former tubing string running and pulling device hoist engine, this cylinder is promptly controlled drop hanger 8 and is risen and fallen, second joint of also controlling suspension rod 9 rises and falls, two effects of a cylinder are very inconvenient, increase by one and pay cylinder 19, by rising and falling of its control suspension rod second joint, master rotor is only controlled rising and falling of drop hanger 8, manipulates more convenient like this.Can increase work efficiency.The hydraulic pressure that is newly equipped with is paid the end that motor 19 is contained in drum shaft 16, and clutch 17 is fixed on the drum shaft 16, with axle with changeing and can endwisely slip, it with pay motor 18 and constitute separation and reunions, in conjunction with the time pay the motor drive roller shaft and rotate, pay motor idle running during disengagement.
Fig. 3 is the horizontal telescoping mechanism of new equipment on trailer 2; Be to constitute by square hole cover 4, guide pillar 5, telescopic oil cylinder 22; But guide pillar 5 in square hole cover 4 under the ejection of oil cylinder 22 level flexible; Fix a bearing 21 in the upper front end of guide pillar 5, blowout hookup 6 is located in above the bearing 21.In the time of need sealing well head, oil cylinder 22 is released guide pillar 5, makes blowout hookup 6 aim at well head, and hoist engine is sling blowout hookup 6 by drop hanger 8, and oil cylinder 22 is with guide pillar 5 withdrawals, and blowout hookup 6 drops on the well head.24 is oil pipes, the 23rd among the figure, is contained in the pulley on the guide pillar 5 in order to reduce friction.
Fig. 4 is the schematic diagram of oil circuit; 15 is main oil pumps of former tubing string running and pulling device among the figure, and it makes it work to main motor 13, pair motor 17, supporting oil cylinder 10, telescopic oil cylinder 22, brake oil cylinder 34 fuel feeding.Pay oil pump 14 and make it work to the master cylinder 27 of blowout hookup, slips oil cylinder 35 fuel feeding of blowout hookup.
Two above-mentioned oil circuits make it UNICOM by two one way valves 30 and 26, two hydraulic control one-way valves 29 and 31, two hydraulic control two position two-way valves 28 and 32 and constitute the bridge-type hydraulic circuit.Usual two hydraulic control one-way valves 29,31 are in cut-off state, two hydraulic control two position two-way valves 28,32 are in conducting state, 6 systems are in not duty when the hydraulic pressure blowout hookup, when tubing string running and pulling device system is in running order, the oil piping system increased pressure of main motor 13, the two position two-way valve 28 that this oil circuit is controlled is become by conducting and ends, hydraulic control one-way valve 31 becomes conducting by ending, make tubing string running and pulling device oil piping system and hydraulic pressure blowout hookup oil piping system be unified into path, then the hydraulic oil of two table oil pumps, 15,14 conveyings all enters tubing string running and pulling device oil piping system; When running and pulling device is not worked, during blowout hookup work, hydraulic pressure blowout hookup oil piping system oil mass is increased; When two oil piping systems were all in running order, two hydraulic control one-way valves 29,31 in the bridge-type oil circuit were all by by becoming conducting, and two hydraulic control two position two-way valves 28,32 are all become by conducting and end, and make two oil circuits form paths; When one of them oil piping system needs bigger work oil mass, when another oil piping system needs less work oil mass, can realize by control hand-operated direction valve 33.Have the hand-operated direction valve of eight different hydraulic pressure original papers of control in the oil circuit.
Clutch 17, interposed clutch 20 employing end faces are that the dental forceps clutch of convex concave is advisable, and this clutch configuration is simple, low price; But also can adopt friction clutch, the clutch of awl tooth.
