Technical field
The utility model is related to oil extraction in oil field technical fields, and in particular to a kind of oil bailing device anti-sticking step by step.
Background technology
With deepening continuously for oil field development, especially low permeability oil and gas field exploitation to middle and later periods, some oil wells yield drop
Low, hole condition is deteriorated, and well exploitation input is excessively high.In order to realize cost efficiency, cost of winning is reduced, each oil field is according to practical need
It asks, oil bailing device can be increased and recovered the oil to oil well.Involving swab technique is the fuel-displaced situation according to stripper well, regularly disposably
Swab is put by steel wire rope in oil well casing with dredging vehicle or hoist engine, keeps swab dive certain to oil reservoir
After depth, then swab self-closed is promoted swab by dredging vehicle or hoist engine, be isolated by swab close
The oil reservoir for being enclosed in top is promoted with swab to ground, reaches involving swab purpose.
By the way that bailing well involving swab technological development situation analysis in recent years, involving swab technique is common sleeve type involving swab work at present
Tool partly uses valve formula involving swab tool, but cannot all solve the problems, such as card well, without timely pressure release and unfreezing function, causes
Part well steel wire rope is broken by force, is made troubles to follow-up salvaging, while increasing bailing well and scrapping risk.
Utility model content
In order to solve the problems in the existing technology, the utility model provides a kind of oil bailing device anti-sticking step by step, this
Device is to be based on being improved on the basis of common involving swab tool, increases the emptying function that is hampered, anti-sticking function while reserving
Fishing joint function solves involving swab and is slightly hampered in the process, emptying unfreezing problem, while increasing the solution of secondary pressure shear pin
Involving swab tool card well salvages difficult problem, while also solving involving swab remaining oil problem at well head, greatly reduces employee
Working strength.
The utility model technical scheme applied to solve the technical problem is as follows：
Anti-sticking oil bailing device step by step, the device include：
Central tube, the side surface of the central tube radially multiple gap of circumference uniform distribution；
Fishing joint, the fishing joint are arranged in the upper end of the central tube；
Sealing drum, the sealing bucket are arranged on the outside of the central tube, and central tube clearance fit, described in height covering
Gap on central tube；
Sleeve, the sleeve are sleeved on the outside of central tube lower end；
Bailing unloads plunger, and the bailing unloads in the centrally disposed pipe lower end in one end of plunger, matches with central tube interference
It closes；
Shear pin is unloaded, radially circumference uniform distribution prevents from fastening the bailing unloading unloading shear pin in the sleeve
It falls off after plunger unloading；
Counterweight joint, the counterweight joint are mounted on the lower end of bailing unloading plunger, and are assembled together with sleeve.
The utility model has the beneficial effects that：The connection type that existing swab connector is bottom plunger is improved,
Thoroughly solve the problems, such as that well head remaining oil lands when involving swab, reduces environmental pollution.The apparatus structure is simple, easy to operate,
Wide adaptability.Separator can ensure twice, and plunger is hampered after once cutting if it is the sealing swollen envelope of bucket, then can normal bailing
Oil bailing device and counterweight are stuck in casing if it is oil bailing device to ground, then can ensure that steel wire rope completely proposes pit shaft,
It descends operation to salvage again, realizes never card well function；Wherein bailing unloading plunger is cut by the quenched progress pressure of material and is calculated,
It can ensure that the timely cutting that is hampered, pressure cut grade and can have a wide range of application with designed, designed.Good in economic efficiency, this device can
To ensure the normal emptying of well that is hampered, realize that bailing prevents swab from falling the generation of well accident

Specific implementation mode
The utility model is described in further details with reference to the accompanying drawings and examples.
Anti-sticking oil bailing device step by step, the device include：Steel wire rope sheath 1, fishing joint 2, secondary shearing bolt 3, center
Pipe 4, location nut 5, a pair of of bucket sheath, sealing bucket 7, sealing ring 9, sleeve 10, gap 11, bailing unloading plunger 12, unloading are cut
Nail 13 and counterweight joint 14.Central tube 4 described in the main body of oil bailing device, side surface radially multiple gap 11 of circumference uniform distribution,
The import that oil enters central tube is provided for oil bailing device, in the both sides up and down of the gap 11, the both ends of central tube are arranged
Two groups of location nuts 5；The fishing joint 2 is arranged in 4 upper ends of the central tube, passes through secondary shearing bolt 3 and steel wire rope
Protective case 1 assembles.After entire main body is stuck, secondary shearing bolt 3 is cut, and steel wire rope sheath 1 is detached with main body, operating personnel
Main body can be salvaged by fishing joint 2 to well head to use, fishing joint 2 is 2 cun of half center pipe fitting of standard, can be met interior
Outer salvaging demand.The sealing bucket 7 setting is in 4 outside of the central tube, and 4 clearance fit of central tube, described in height covering
Gap 11 on central tube 4；Sealing 7 upper and lower ends of bucket install a upper bucket sheath 6 and lower bucket sheath 8 respectively, and lower bucket sheath 8 is logical
Cross the sealing of sealing ring 9.The sleeve 10 is sleeved on the outside of 4 lower end of central tube；The lower ending opening of the central tube 4, passes through bailing
Unloading plunger 12 is sealed 4 lower end of central tube, and bailing unloads plunger 12 and is arranged in sleeve 10, and upper end connects with steel wire rope
It connects.The unloading shear pin 13 is distributed on along 4 radial circumference of central tube in the sleeve 10, and the fixed bailing unloads plunger 12；
The counterweight joint 14 is mounted on the lower end of bailing unloading plunger 12, is assembled together with sleeve 10.
When starting involving swab, steel wire rope decentralization.Under gravity, oil bailing device starts to fall, and sealing bucket 7 thereon exists
It is moved upwards under the action of oil well casing frictional force, 7 stop motion of sealing bucket is made by location nut 5 above, is sealed at this time
Bucket 7 exposes the gap 11 of central tube 4, that is, the oil inlet of central tube 4, so that crude oil is passed through gap 11 and enters in central tube 4.It reaches
When to specified involving swab height, oil bailing device is above carried, sealing bucket 7 position original back under the action of frictional force, under
The location nut in face positions, and gap 11 is by 7 deadend of sealing bucket at this time.It is close under the action of sealing oil column gravity above bucket 7
Seal the dilatancy that bucket 7 is axially compressed and generation is radial.The crude oil of the pulling of steel wire rope at any time, oil bailing device top is carried
It is raised on ground.When the quality of crude oil is more than rated weight, it is located at the bailing inside central tube 4 and unloads plunger 12 along central tube
Broken end, crude oil by opening let out in Hui Jing, reduce the weight of main body；But steel wire rope still can not be pulled at this time, is unloaded
Shear pin 13 can be broken, and counterweight joint 14 and bailing unloading plunger 12 are also separated with main body, are fallen into well, are reduced main body again
Weight；If oil bailing device, which is stuck in well, to be pulled out, secondary shearing bolt 3 is broken automatically, and steel wire rope and steel wire rope is made to protect
1 safety of set pulls out well head, and when subsequent rescue is salvaged by fishing joint 2.
