Abstract
The utility model discloses a tool for installing a seal ring of a casing pressure tapping device for a water injection well. The tool for installing the seal ring of the casing pressure tapping device for the water injection well mainly solves the problem that in the prior art, a large amount of time and a large amount of strength are consumed when the seal ring on the casing pressure tapping device is replaced, and the replacement efficiency is low. The tool for installing the seal ring of the casing pressure tapping device for the water injection well is characterized in that a bench is arranged on the lower portion of a push head (1) and placed in a hole in the upper end of the casing pressure tapping device, a pull rod is transversely connected to the upper portion of the push head (1), the lower portion of a leading head (2) is conical, a bench is arranged on the upper portion of the leading head (2) and placed in a hole in the lower end of the casing pressure tapping device, and an axial taper hole is formed in the upper portion of a casing top cylinder (3). The tool for installing the seal ring of the casing pressure tapping device for the water injection has the advantages that both time and labor are saved when the seal ring is replaced, and the replacement efficiency is high.
Description
Technical field:
The utility model relates to oil extraction in oil field field to be got cover pressure device sealing ring and changes instrument used, and especially water injection well is got cover pressure device mounting tool for sealing ring.
Background technology:
In oil extraction in oil field field, the sealing ring that water injection well is got cover pressure device used after a period of time, and because the reasons such as wearing and tearing, crackle cause, to get cover pressure device poorly sealed, affected and enrolled the accuracy of pressure, thereby need to more exchange sealing ring on casing pressure device for.Because seal diameter is little, thickness is large, elasticity is little, and it is large to get the diameter of cover pressure device, and in the time more exchanging on casing pressure device sealing ring for, existing wastes time and energy, and changes inefficient problem, affects water injection well water-injection efficiency.
Utility model content:
Existingly more to exchange sealing ring on casing pressure device for and waste time and energy in order to overcome, change inefficient problem.The utility model provides a kind of water injection well to get cover pressure device mounting tool for sealing ring.This water injection well is got cover pressure device mounting tool for sealing ring, and to have the sealing ring of replacing time saving and energy saving, changes the high feature of efficiency.
The technical solution of the utility model is: this water injection well is got cover pressure device mounting tool for sealing ring and comprised and cut somebody's hair, take the lead and overlap top cylinder.There is stage the bottom of cutting somebody's hair is placed in and gets in cover pressure device upper end hole, and the upper lateral of cutting somebody's hair is connected with tommy bar, and leader bottom be conical, and there is stage on leader top is placed in gets in cover hole, pressure device lower end, and axial taper hole is arranged at a top, cover top.
The utlity model has following beneficial effect: this water injection well is got cover pressure device mounting tool for sealing ring because there is stage the employing bottom of cutting somebody's hair is placed in and gets in cover pressure device upper end hole, the upper lateral of cutting somebody's hair is connected with tommy bar, leader bottom is conical, there is stage on leader top is placed in gets in cover hole, pressure device lower end, the structure of axial taper hole is arranged at cylinder top, cover top, utilization is cut somebody's hair and is promoted to get cover pressure device downwards, sealing ring is enclosed within on leader, upwards promote sealing ring by cover top cylinder again, and then time saving and energy saving, efficiency is high changes sealing ring, and simple in structure.This water injection well is got cover pressure device mounting tool for sealing ring to have the sealing ring of replacing time saving and energy saving thus, changes the high feature of efficiency.
Accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation.
In figure, 1-cuts somebody's hair, 2-leader, 3-cover top cylinder.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, this water injection well get cover pressure device mounting tool for sealing ring comprise cut somebody's hair 1, leader 2 and cover top cylinder 3.There is stage 1 bottom of cutting somebody's hair is placed in and gets in cover pressure device upper end hole, and 1 upper lateral of cutting somebody's hair is connected with tommy bar, 1 the downward impetus of cutting somebody's hair.Take the lead 2 bottoms for conical, and conical large end external diameter is with to get cover pressure device external diameter identical, and there is stage on leader 2 tops is placed in to get to be overlapped in hole, pressure device lower end, 2 guiding function of taking the lead.Axial taper hole is arranged at cylinder 3 tops, cover top, and cover top cylinder 3 plays upwards pushing tow sealing ring effect.
When actual use:
The 1 bottom stage of cutting somebody's hair that this water injection well is got to cover pressure device mounting tool for sealing ring is placed in gets in cover pressure device upper end hole, the 2 top stages of taking the lead are placed in gets in cover hole, pressure device lower end, sealing ring is enclosed within the conical bottom of leader 2, again leader 2 bottoms are placed in the cylinder 3 upper axial taper holes of cover top, firmly cut somebody's hair 1 again, leader 2 moves in cylinder 3 taper holes of cover top, cover top cylinder 3 is pushing away sealing ring and is moving up along leader 2 taper seats, finally sealing ring is drawn and get in the outer groove of cover pressure device by leader 2 taper seats, complete and more exchange sealing ring operation on casing pressure device for.
This water injection well is got cover pressure device mounting tool for sealing ring through field experiment, compared with general tool, raises the efficiency more than 3 times, and a people just can operate, and as long as former replacing sealing ring needs 5 minutes, now several seconds.And simple to operate, processing charges is low, time saving and energy saving, improved operating efficiency and personal safety.For injecting enough water, injecting good water provide guarantee.
