Abstract
The utility model belongs to the design and manufaction technical field of paraffin removal from oil well implement, particularly relate to a kind of paraffin cleaner of the reducing for oil field wax removal operation of improvement, comprise knife rest, consolidation is arranged on the blade support on knife rest, dextrorotation paraffin cutting blade on knife rest and derotation paraffin cutting blade is arranged on by blade support, described dextrorotation paraffin cutting blade is identical with derotation wax spatula chip architecture, but be that axle is oppositely arranged with knife rest, dextrorotation paraffin cutting blade and derotation paraffin cutting blade entirety are in " 8 " font; Uniform on described dextrorotation paraffin cutting blade and derotation paraffin cutting blade blade breach is set.This reducing paraffin cutting blade, can make equipment produce distortion undergauge at hard wax and oil pipe reducing place, ensure to pass through smoothly, avoid bit freezing occurs.
Description
Technical field
The utility model belongs to the design and manufaction technical field of paraffin removal from oil well implement, particularly relates to a kind of paraffin cleaner of the reducing for oil field wax removal operation of improvement.
Background technology
When oil well production, crude oil rises to the process of well head from shaft bottom, and temperature and pressure reduces gradually, and when the condensation point of temperature and pressure lower than wax, wax material just starts to be deposited on tube wall, causes oil flow channel to reduce, thus oil well output is significantly reduced.So for the well of easy wax deposition, regularly wax removal operation will be carried out, to ensure oil well output.But existing mechanical paraffin removal paraffin scraper external diameter is fixing, for the easy bit freezing in position of harder wax and oil pipe reducing, and existing paraffin scraper is monolithic blade, the wax scaled off is all larger, the wax cut is made to be difficult to upper row rapidly, easily cause crown drill, blade is that one-way spiral easily causes steel wire to beat to turn round, add the risk of underground work in addition.
Summary of the invention
The purpose of this utility model is: the paraffin cleaner providing a kind of reducing, can effectively prevent from steel wire from beating turning round, crown drill equivalent risk.
The technical scheme solving the problems of the technologies described above employing is: a kind of paraffin cleaner of the reducing for oil field wax removal operation of improvement, comprise knife rest, consolidation is arranged on the blade support on knife rest, dextrorotation paraffin cutting blade on knife rest and derotation paraffin cutting blade is arranged on by blade support, described dextrorotation paraffin cutting blade is identical with derotation wax spatula chip architecture, but be that axle is oppositely arranged with knife rest, dextrorotation paraffin cutting blade and derotation paraffin cutting blade entirety are in " 8 " font; Uniform on described dextrorotation paraffin cutting blade and derotation paraffin cutting blade blade breach is set.Described blade breach is arch gate-shaped or triangular shape or rectangular-shaped.
The beneficial effects of the utility model: a kind of reducing paraffin cutting blade that the utility model manufactures and designs, on the basis of existing paraffin scraper, blade has some osculums, equipment can be made to produce distortion undergauge at hard wax and oil pipe reducing place, ensure to pass through smoothly, avoid bit freezing occurs; Wax spatula group comprises 2 paraffin cutting blades, and wax is cut into small pieces by breach type blade, makes wax upper row, avoids wax to bond together, cause crown drill; Have two paraffin cutting set of blades during operation, a right-handed screw, another backpitch, such paraffin cutting blade moment of torsion suffered when cutting wax is cancelled out each other, and steel wire can not be made to beat and turn round.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is main TV structure schematic diagram of the present utility model, dextrorotation paraffin cutting blade 1, knife rest 2, derotation paraffin cutting blade 3; Accompanying drawing 2 is structural representations of paraffin cutting blade, blade breach 5, blade support 4.
Detailed description of the invention
The paraffin cleaner of the reducing for oil field wax removal operation of embodiment 1, a kind of improvement, as shown in Figures 1 and 2, comprise knife rest 2, consolidation is arranged on the blade support 4 on knife rest 2, dextrorotation paraffin cutting blade 1 on knife rest 2 and derotation paraffin cutting blade 3 is arranged on by blade support 4, described dextrorotation paraffin cutting blade 1 is identical with derotation paraffin cutting blade 3 structure, but oppositely arranges for axle with knife rest 2, and dextrorotation paraffin cutting blade 1 and derotation paraffin cutting blade 3 entirety are in " 8 " font; Uniform on described dextrorotation paraffin cutting blade 1 with derotation paraffin cutting blade 3 blade breach 5 is set.Described blade breach 5 is in arch gate-shaped or triangular shape or rectangular-shaped.During operation, paraffin scraper is put into well by steel wire traction, under the effect of weighted lever gravity, paraffin scraper moves down, and carries out paraffin cutting operation.Positive and negatively when wax removal operation revolve that paraffin cutting blade is stressed cancels out each other, thus avoid steel wire to beat turning round; The blade of breach type can make blade have elasticity at hard wax or oil pipe undergauge place, produces distortion, smoothly by undergauge place, avoids bit freezing; Breach type blade has very strong broken wax ability simultaneously, ensures that the wax scaled off is all fritter, is conducive to the upper rapidly row of wax, avoids wax to bond together, cause crown drill.
Claims (2)
1. the paraffin cleaner of the reducing for oil field wax removal operation improved, comprise knife rest (2), consolidation is arranged on the blade support (4) on knife rest (2), dextrorotation paraffin cutting blade (1) on knife rest (2) and derotation paraffin cutting blade (3) is arranged on by blade support (4), it is characterized in that: described dextrorotation paraffin cutting blade (1) is identical with derotation paraffin cutting blade (3) structure, but with knife rest (2) for axle is oppositely arranged, dextrorotation paraffin cutting blade (1) and derotation paraffin cutting blade (3) entirety are in " 8 " font; Uniform blade breach (5) is set described dextrorotation paraffin cutting blade (1) and derotation paraffin cutting blade (3) are upper.
2. paraffin cleaner according to claim 1, is characterized in that: described blade breach (5) is in arch gate-shaped or triangular shape or rectangular-shaped.
