Abstract
A non-location oil pipe plugging device in the petroleum industry oil gas exploiting machinery technical field comprises a balancing core rod 1, a seat sealing mandrel 2, a deblocking pull seat 3 and a locking conical seat 9, wherein the balancing core rod 1 is connected with the seat sealing mandrel 2 through a shear pin 16; the deblocking pull seat 3, the locking conical seat 9, an ebonite retaining ring 11, a sealing rubber tube 12 and a balancing tube 13 are orderly covered outside the seat sealing mandrel 2. The utility model can be placed down to an accomplished blank tubing gas well, can assume underground well closing function, and can be conveniently placed down and lifted out by using steel wire operating tools, which is reliable in sealing and secure in deblocking.
Description
The utility model relates to a kind of downhole tool of petroleum industry oil-gas mining field of mechanical technique, specifically: be not have the location tubing plug.
In natural gas and high pressure oil exploitation, often need carry out provisional obstruction in the down-hole to the oil gas well, be beneficial to carry out snubbing serving, the protection oil-gas Layer for changing well head, is changed the above oil pipe of oil reservoir, also need oil pipe be stopped up in the down-hole.The tubing plug that step is arranged of gas field use at present must insert in oil pipe string and be located in pipe nipple, be placed with the step tubing plug then down, it is snapped among the draw-in groove that is located in, realize the effect of seat shutoff plug, its shortcoming is the well to finishing in early days, since in the oil pipe string not joint chair fall pipe nipple and can't use, also can't realize at an arbitrary position stopping up.
The purpose of this utility model is to provide a kind of and can realizes the seat envelope and stop up in the optional position in oil pipe, need not insert the nothing location tubing plug that is located in pipe nipple in the oil pipe string separately.
The utility model is achieved in that and includes balance core bar 1, seat envelope axle 2, deblocking pulling seat 3, just block spring 5, voussoir 6, slips 7, locking cone seat 9, ebonite shelves ring 11, cartridge 12, surge drum 13, positioning sleeve 14, normal dog 15, cut off 16, sealing 19, balance core bar 1 is connected by cutting off 16 with seat envelope axle 2, the seat envelope axle 2 outer deblocking pulling seats 3 that are with successively, locking cone seat 9 ebonite shelves rings 11, cartridge 12, surge drum 13, slips 7 and voussoir 6 are housed respectively on deblocking pulling seat 3, card spring 5 is just arranged between deblocking pulling seat 3 and the voussoir 6, on the locking cone seat 9 fixing present envelope axles 2, the annular space that surge drum 13 and balance core bar are 1 is equipped with positioning sleeve 14, ebonite shelves ring 11 is arranged on the cartridge 12, positioning sleeve 14 is arranged in the surge drum 13, normal dog 15 and seal 19.
The utility model also adopts following technical scheme:
Fluted on the deblocking pulling seat 3.
Just card spring 5 is enclosed within slips 7 and voussoir 6 and the deblocking pulling seat 3.
The inclined-plane at slips 7 and voussoir 6 tops is corresponding with the groove inclined-plane of deblocking pulling seat 3, and the inclined-plane is corresponding with locking cone seat 9 inclined-planes in the lower end.
On locking cone seat 9 inner ring surfaces slip insert is arranged.
On the positioning sleeve 14 jump ring is arranged, and jump ring can be locked in the draw-in groove of surge drum 13.
Balance core bar 1 axially has through hole 20, and radially perforation 17, and perforation 18 on the surge drum 13, can be communicated with between through hole 20 and the eyelet 17,18.
Advantage of the present utility model is: can be lowered at the blank tubing gas well of having finished, can bear the downhole closing function, can be lowered to and trip out with the steel wire operation tool easily, sealing be reliable, the deblocking insurance.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model includes balance core bar 1, seat envelope axle 2, deblocking pulling seat 3, just block spring 5, voussoir 6, slips 7, locking cone seat 9, ebonite shelves ring 11, cartridge 12, surge drum 13, positioning sleeve 14, normal dog 15, cut off 16, sealing 19 etc., with cutting off 16 a balance core bar 1 and a seat envelope axle 2 linked together, go into well from lubricator, at this moment, slips 7 is just blocking under the promotion of spring 5, skid off by inclined-plane 4, being close to tubing wall slides downwards, because of locking cone seat 9 locks with cutting off 10, so, seat envelope axle 2 and locking cone seat 9 can not bored DL synchronization into slips 7 the blanking plug grappling.Instantly arrive the position, on put forward a seat envelope axle 2, locking cone seat 9 is also together up, and awl is gone into slips 7 with the blanking plug grappling, continues uply to carry out jarring with the wire rope operation tool, cut off and cut off 10, compression seal packing element 12 hits on exerting oneself repeatedly simultaneously, and slips 7 is stung tight oil pipe, reaction force is stung the locking tooth 8 on the locking cone seat 9 on the present envelope axle 2 simultaneously, when on hit repeatedly, connect the steel wire operation tool and cutting off of axle 2 of seat envelope articulates, at this moment, balance eyelet 17,18,20 at connected state, upwards jarring again, positioning sleeve 14 is locked in the groove normal dog 15 to top offset, close each balance eyelet, pintle hook lock balance core bar 1 makes balance core bar 1 can not guarantee the reliability of stopping up from line displacement under the external force collision in addition, after simultaneously the connecting pin of steel wire operation tool and balance core bar 1 being cut off, finish the seat envelope.Remove blanking plug: with wire rope operation tool band grappling tool, the first step is caught the 1 upwards jarring of balance core bar, cut off and cut off 16, balance core bar 1 is pulled out blanking plug, make strata pressure and oil pipe liquid annotate pressure balance, could play ground smoothly by intercommunicating pore 18, second step was lowered to grappling tool again and grabs on the card deblocking pulling seat 3 and propose jarring, because of slips 7 has the bigger axial pulling amount of scurrying, and voussoir 6 amounts of scurrying are very little, so, when making progress jarring, elder generation's jarring voussoir 6, after voussoir 6 pulled out, slips 7 can become flexible, again slips 7 is pulled out, at this moment, all component are all loosening, can smoothly tubing plug be tripped out.
