Abstract
The utility model relates to a special tool for pulling sucker rod which solves the problem that the centering ring is easily scraped to fall into the well. The special tool for pulling sucker rod is characterized in that a coupling (3)and a changed head (5)are fastening connected at both ends of the short joint(4) The other end of the changed head (5) is inserted into a steel cable (7)with a rope fastener(9). The steel cable (7) is fixed by the lead-tin alloy filler (6) in the changed head (5). The other end of the coupling (3) is fastening connected with a hand basket (2) with a slot (8) at one end. The sphere end of a joint (1) is movably inserted into the big opening of the slot (8). The pulling tool is simultaneously used with the oil pipe pulling tool to make the oil pipe and the sucker rod be simultaneously lifted and effectively avoid the centering ring from falling into the well. The special tool for pulling sucker rod is simple and is easy to operate and shortens the repairing period of the pump well.
Description
Technical field:
The utility model relates to a kind of producing well well bar pulling tool, has belonged to and has pulled out the sucker rod special tool.
Background technology:
When the maintenance producing well, if disconnected taking off appears in oil pipe, just R a T need be risen and pull out, change or repair.And the present draw out method that rises is that the R a T branch opens and pulls out, and earlier sucker rod is extracted with the rod elevator instrument, and then with the pipe elevator instrument oil pipe is extracted; And such draw out method that rises when rising when pulling out sucker rod, when the centering ring on the sucker rod takes off the place through oil pipe is disconnected, just is easy to be scraped and falls in the well, makes the normal maintenance of producing well to carry out, and needs carry out large repairs to this well.
The utility model content:
Centering ring is easily scraped the problem in the well when pulling out inspection pump sump R a T in order to have solved, the utility model provides a kind of to pull out the sucker rod special tool, this instrument can avoid centering ring to fall in the well effectively, and R a T is extracted simultaneously in the inspection pump sump, easy, easy operating have shortened the time between overhauls(TBO) of examining pump sump.
The technical solution of the utility model is: this instrument comprises short circuit, the screwed connection of short circuit two ends has box cupling and becomes head, and the other end that becomes head is inserted the wire rope that has sling, and fixes with filler, the other end screwed connection of box cupling has the hand basket of an end with groove, and joint is inserted in activity in the groove.
Above-mentioned said filler is a terne metal; One end of joint is spherical, and the other end is a screw thread; The opening of groove be one big, one little.
The beneficial effect that the utlity model has is: this instrument is to utilize the sling of wire rope to be suspended on the hook of travelling block, the direct and sucker rod screwed connection of the joint of bottom; Cooperate the oil pipe pulling tool also to be stuck on the oil pipe simultaneously, the other end also hangs on the hook of travelling block; And utilize sucker rod pulling tool and rope capacity to adjust the length difference of R a T, R a T is tripped out simultaneously, centering ring is easily scraped and is fallen in the well when having avoided independent to pull out sucker rod effectively, and easy, easy operating has shortened the time between overhauls(TBO) of examining pump sump.
Description of drawings:
Accompanying drawing 1 is the utility model configuration diagram.
1-joint among the figure, the 2-hand basket, the 3-box cupling, the 4-short circuit, 5-becomes head, 6-filler, 7-wire rope, 8-groove, 9-sling.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this pulls out the sucker rod special tool and comprises short circuit 4, box cupling 3 is arranged and become 5 in the screwed connection of the two ends of short circuit 4, become an other end of 5 and insert the wire rope 7 that has sling 9, wire rope 7 is fixed with terne metal filler 6 becoming in 5, the other end screwed connection of box cupling 3 has the hand basket 2 of an end with groove 8, the opening of groove 8 be one big, one little, the spherical termination activity of joint 1 is inserted in the major part opening of groove 8.
In actual use, earlier the oil pipe pulling tool is stuck on the oil pipe, the other end hangs on the hook of travelling block, the sling 9 of oil pipe pulling tool wire rope also hangs on the hook of travelling block, then with joint 1 screwed connection on sucker rod, again the spherical termination of joint 1 is inserted in the groove 8, and be stuck in the little opening part of groove 8, be used for bearing the weight of sucker rod, and the sucker rod pulling tool is lowered in the oil pipe, adjust the length difference of oil pipe and sucker rod simultaneously, start coaster at last, with sucker rod with take out pipe and trip out simultaneously.After the first segment R a T is tripped out, pull down pulling tool, transport working oil pipe and the sucker rod extracted; Save on the sucker rod second with another joint 1 screwed connection, repeat aforesaid operations, R a T one joint one can be saved land trips out.This pulling tool and oil pipe pulling tool use simultaneously, and oil pipe and sucker rod are tripped out simultaneously, have avoided centering ring to fall in the well effectively, and easy, easy operating has shortened the time between overhauls(TBO) of examining pump sump.
