The present invention has following beneficial effect: this workover treatment well head environmental protection and energy saving tubing string liquid drainage device is tubbiness owing to adopting in main body, main body is gone to the bottom and is connected with support ring between two parties, two engaging lug upper hinges of support ring both sides are connected with block teeth, block teeth upper end chain connection has upper connecting rod, block teeth upper end passes the axial strip hole in main body both sides, block teeth upper end is acute angle, upper small end is carried sheet strip hole through unblock and is connected with locking spring, main body upper surface is connected with making leaf spring, making leaf spring is equipped with cleaner, unblock is carried on sheet and is connected with 2 release levers, release screw bolt is through cleaner, making leaf spring and support ring are connected with seal plug, on release screw bolt between seal plug and support ring, cover has Packing spring, seal plug is conical, main body upper end outer ring boss is connected with locating ring, locating ring upper hinge is connected with pressure-raising bar, upper pressure-raising bar right-hand member and cleaner chain connection, upper pressure-raising bar left end is connected with the structure of rope chain.Seal plug is utilized to be held by well liquid in oil pipe, after a upper oil pipe and lower oil pipe are dismantled, in recycling, seal plug opened by pressure-raising bar, well liquid in oil pipe is put into wellhead casing pipe by funnel, reach the object of drainage, solve existing liquid storage tank drainage operating cost high, the problem of complicated operation, improve preventing polluting effect.To have operating cost low for this workover treatment well head environmental protection and energy saving tubing string liquid drainage device thus, feature simple to operate.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is Fig. 1 right views.
1-main body in figure, 2-support ring, 3-block teeth, the upper connecting rod of 4-, 5-unlocks and carries sheet, 6-making leaf spring, 7-cleaner, 8-seal plug, 9-locating ring, the upper pressure-raising bar of 10-, 11-release lever.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in the figure, this workover treatment well head environmental protection and energy saving tubing string liquid drainage device comprises main body 1.Main body 1 is tubbiness, and main body 1 has annular boss outside upper end, and annular boss diameter is identical with tubing coupling diameter, annular boss has annular groove, and main body 1 lower outer diameter is less than tubing coupling internal diameter, and axially there is strip hole two side, main body 1 bottom, there is the end main body 1 lower end, and there is via hole at Di Shang center.The via hole at main body 1 end is built-in with support ring 2, and support ring is fixed on by nut for 2 times at main body 1 the end.Two engaging lug upper hinges of support ring 2 both sides are connected with block teeth 3, block teeth 3 upper end chain connection has upper connecting rod 4, block teeth 3 upper end passes the axial strip hole in main body 1 both sides, block teeth 3 upper end is acute angle, upper connecting rod 4 upper end is carried sheet 5 strip hole through unblock and is connected with locking spring, main body 1 upper surface is connected with making leaf spring 6, making leaf spring 6 is equipped with cleaner 7, unblock is carried on sheet 5 and is connected with 2 release levers 11, on carry release lever 11 block teeth 3 and to retract main body 1, the wedge angle unclamping release lever 11 block teeth 3 is stuck on tubing coupling screw thread under locking spring action, main body 1 is locked in tubing coupling.Release screw bolt is through cleaner 7, making leaf spring 6, support ring 2, fixed by nut after seal plug 8 and pad, seal plug 8 is quality of rubber materials, release screw bolt between seal plug 8 and support ring 2 overlaps and has Packing spring, seal plug 8 is up big and down small taper shape, locating ring 9 is connected with in main body 1 annular groove, locating ring 9 upper hinge is connected with pressure-raising bar 10, upper pressure-raising bar 10 left part is straight, upper pressure-raising bar 10 right part is approximate circle arc, upper pressure-raising bar 10 right-hand member and cleaner 7 chain connection, upper pressure-raising bar 10 left end is connected with rope chain, under normal circumstances, seal plug 8 is on the oil pipe termination of Packing spring effect lower seal in tubing coupling, negative pressure is produced in oil pipe, well liquid is inhaled in oil pipe, effectively prevent well liquid from leaking, during lower stay cord chain, upper pressure-raising bar 10 right-hand member is up, drive cleaner 7 up, cleaner 7 up drive release screw bolt is up, the movable sealing of release screw bolt up compression seal spring band is stifled 8 up, seal plug 8 depressurization, in oil pipe, well liquid releases.
The course of work:
The picking up the ears of well head big four connects and the funnel communicated in sleeve pipe, when workover treatment tubing coupling seat is on well head, in portable release lever 11 block teeth 3 indentation main body 1, again this workover treatment well head environmental protection and energy saving tubing string liquid drainage device is put into tubing coupling, block teeth 3 are stuck on tubing coupling screw thread, seal plug 8 is on the oil pipe termination of Packing spring effect lower seal in tubing coupling, at this moment tubing string is carried on, the screw thread that to be connected with next root oil pipe is dismantled when next root oil pipe seat is on well head, after dismantling, a upper oil pipe lower end aligned is connected to the funnel communicated with sleeve pipe, or aim at taper hole on well head big four, lower stay cord chain seal plug 8 depressurization, in a upper oil pipe, well liquid is by funnel or let out back in sleeve pipe by taper hole on well head big four, thus operating cost is reduced, simplify the operation course, and environmental protection and energy saving, improve operating efficiency, increase oil recovery benefit.
