The present invention has following beneficial effect: this workover treatment is tubbiness with well head environmental protection and energy saving tubing string liquid drainage device owing to adopting in main body, main body is gone to the bottom and is connected with between two parties support ring, 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, the block teeth upper end passes the axial strip hole in main body both sides, the block teeth upper end is acute angle, upper small end pass release carry the sheet strip hole with the locking spring be connected, the main body upper surface is connected with making leaf spring, be equipped with cleaner on the making leaf spring, release is carried and is connected with 2 release levers on the sheet, release screw bolt passes cleaner, making leaf spring and support ring are connected with seal plug, cover has Packing spring on the release screw bolt between seal plug and the support ring, seal plug is conical, is connected with locating ring on the outer ring boss of main body upper end, and the locating ring upper hinge is connected with the pressure-raising bar, upper pressure-raising bar right-hand member and cleaner chain connection, upper pressure-raising bar left end are connected with the structure of rope chain.Utilize seal plug that well liquid in the oil pipe is held, after a upper oil pipe and lower oil pipe are dismantled, the pressure-raising bar is opened seal plug on the recycling, well liquid in the oil pipe is put into wellhead casing pipe by funnel, reach the purpose of drainage, it is high to solve existing liquid storage tank drainage operating cost, and the problem of complicated operation improves preventing polluting effect.This workover treatment has low, the simple to operate characteristics of operating cost with well head environmental protection and energy saving tubing string liquid drainage device thus.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is Fig. 1 right views.
1-main body among the figure, the 2-support ring, the 3-block teeth, the upper connecting rod of 4-, sheet is carried in the 5-release, 6-making leaf spring, 7-cleaner, 8-seal plug, 9-locating ring, the upper pressure-raising bar of 10-, 11-release lever.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing:
As shown in the figure, this workover treatment comprises main body 1 with well head environmental protection and energy saving tubing string liquid drainage device.Main body 1 is tubbiness, and main body has annular boss outside 1 upper end, and the annular boss diameter is identical with the tubing coupling diameter, annular groove is arranged on the annular boss, and main body 1 lower outer diameter is less than the tubing coupling internal diameter, and axially there is strip hole main body 1 bottom on the two side, there is the end main body 1 lower end, and there is via hole at the center at the end.The via hole at 1 end of main body is built-in with support ring 2, and support ring 2 times is fixed on main body by nut at 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 connections have upper connecting rod 4, block teeth 3 upper ends pass the axial strip hole in main body 1 both sides, block teeth 3 upper ends are acute angle, upper connecting rod 4 upper ends pass release carry sheet 5 strip holes with the locking spring be connected, main body 1 upper surface is connected with making leaf spring 6, be equipped with cleaner 7 on the making leaf spring 6, release is carried and is connected with 2 release levers 11 on the sheet 5, on put forward release lever 11 block teeth 3 retraction main bodys 1, the wedge angle that unclamps release lever 11 block teeth 3 is stuck on the tubing coupling screw thread under the locking spring action, and main body 1 is locked in the tubing coupling.Release screw bolt passes cleaner 7, making leaf spring 6, support ring 2, fix by nut behind seal plug 8 and the pad, seal plug 8 is quality of rubber materials, cover has Packing spring on the release screw bolt between seal plug 8 and the support ring 2, seal plug 8 is up big and down small taper shape, be connected with locating ring 9 in main body 1 annular groove, locating ring 9 upper hinges are connected with pressure-raising bar 10, upper pressure-raising bar 10 left parts are straight, upper pressure-raising bar 10 right parts are the approximate circle arc, upper pressure-raising bar 10 right-hand members and cleaner 7 chain connections, and upper pressure-raising bar 10 left ends are connected with the rope chain, under normal circumstances, seal plug 8 produces negative pressure in the oil pipe on the oil pipe termination of Packing spring effect lower seal in tubing coupling, well liquid is inhaled in oil pipe, prevent that effectively well liquid from leaking, during lower stay cord chain, upper pressure-raising bar 10 right-hand members are up, and it is up to drive cleaner 7, cleaner 7 up drive release screw bolts are up, the up compression seal spring band of release screw bolt movable sealing stifled 8 is up, and well liquid releases in seal plug 8 depressurizations, oil pipe.
