Description

Combined type oil well pump standing valve ball fishing socket
Technical field
The utility model is related to oilfield workover treatment underground fishing tool, specifically a kind of combined type oil well pump Standing valve ball fishing socket.
Background technology
To the salvaging of oil well pump valve ball, this kind of small-sized trouble of lost tool in hole of ball seat in oil field operation, conventional instrument has counter follow Ring junk basket, magnet fisher etc., it is poor that such instrument salvages effect.For example:A kind of magnetic force overshot, application number 201220001533.8, simply there is magnetic force in its bottom, there is certain limitation using scope.Targetedly salvage oil well pump Standing valve ball and ball seat, are still a great problem of oil field operation system construction, cause well workover construction period to extend, operating cost Increase, even results in oil well and scraps.
The content of the invention
The purpose of this utility model is beaten aiming at above-mentioned weak point there is provided a kind of combined type oil well pump standing valve ball Dipper.
The purpose of this utility model is realized by following technical proposals:
Combined type oil well pump standing valve ball fishing socket, including:Top connection, female coupling tap, seating nipple, salvage window, cage, draw Footwear.Described combined type oil well pump standing valve ball fishing socket is cylinder-like structure, and female coupling tap is threadedly coupled with seating nipple, seating nipple 3~4, middle part salvaging window, bottom is provided with guide shoe, and the side of guide shoe is provided with cage.
Female coupling tap top in combinations thereof formula oil well pump standing valve ball fishing socket is provided with internal thread top connection.
Salvaging window in combinations thereof formula oil well pump standing valve ball fishing socket is trapezium structure, and bottom connects with seating nipple Connect, inner inclination from top to seating nipple.
Guide shoe in combinations thereof formula oil well pump standing valve ball fishing socket is helical structure, and bottom is set to tip.
The beneficial effects of the utility model are:It is this kind of small suitable for oilfield workover treatment oil well pump valve ball, ball seat The salvaging of type trouble of lost tool in hole, with valve ball, ball seat, female coupling tap three-level salvage function, compact conformation, simple in construction, easy to manufacture, With low cost, safe and reliable, easy for operation, with strong points, disposable fishing success ratio is high, reduces construction period, improves Operating efficiency, saves construction cost.

Embodiment
With reference to accompanying drawing, the utility model will be further described:
Embodiment 1
As shown in figure 1, combined type oil well pump standing valve ball fishing socket, by top connection 1, female coupling tap 2, seating nipple 3, salvaging window 4th, cage 5, guide shoe 6 are constituted.Described combined type oil well pump standing valve ball fishing socket is cylinder-like structure, if female Top connection 1, the screw thread of seating nipple 3 of the mm female coupling taps 2 of internal diameter Ф 75 and long 1500 mm, the mm of external diameter Ф 114, the mm of internal diameter Ф 97 connect Connect, away from the salvaging window 4 that 3 trapezium structures are processed at the mm of 5 top of cage 50 on seating nipple 3, bottom is connected with seating nipple 3, on Portion is to the inner inclination of seating nipple 3, and bottom is the sophisticated guide shoes 6 of long 250mm provided with helical structure, bottom, and the side of guide shoe 6 is provided with Ф 55mm cages 5.
Embodiment 2
Operating method:First, slowly decentralization combined type oil well pump standing valve ball fishing socket is to top of fish and rotation simultaneously adds 5 KN are pressed to 10 KN;Secondly, after finding that salvage kelly bar deepens suddenly, illustrate that steel ball is successfully introduced dipper, steel ball enters Cage 5;3rd, slow upper lifting pipe post 100mm are to 200mm, then transfer tubing string when finding to salvage kelly bar intensification, illustrate steel ball quilt Successful righting continues to transfer fishing tool and then upper lifting pipe post on ball seat, is connect using salvaging window 4 and dragging for 88.9 mm oil pipes At hoop, if examination proposes load increase, illustrate to drag for and obtain junk, realize and salvage;4th, such as ball seat lower tubular column is more or is blocked by sand, dirt, work Making cylinder 3 can not all pull out, with regard to 10 KN to 15 KN that using the female coupling tap 2 being connected on seating nipple 3, pressurize, rotate after thread making simultaneously Rise and down open tubular column;5th, suitable fishing tool is being selected according to top of fish situation, is implementing new salvaging scheme, until falling in well Thing is all pulled out.
