Abstract
A kind of scraping righting stabilizer, including shell, shell covers outside transmission shaft, and there are two corresponding protruding rings for setting between transmission shaft inside housings, at the central exterior surface major diameter of shell, have through three line spiral bar made of special Milling Machining, the outer surface centre welding-on wear-resistant strip of spiral bar, both sides hardfacing alloy material.The lower end of shell is limited on transmission shaft by simultaneously cap.
Description
Technical field
The present invention relates to oil drilling and geologic prospect casing for well drilling scraper and spiral righting stabilizer technical field,
It is specifically a kind of with scraping function and the spiral stabilizer of centralizing function to be played.
Background technique
Traditional casing scraper can only scraping casing in smaller range deformation, and traditional spiral righting stabilizer
When can only play centralizing function, and use can only single use, largely effect on construction operation progress.
Summary of the invention
In order to solve the problems in background technique, the present invention provides a kind of scraping righting stabilizer, can be to inside pipe casing
A certain range of deformation plays scraping, and can play righting, stable in casing.
The technical scheme is that a kind of scraping righting stabilizer, including shell, shell cover outside transmission shaft, and
Setting at the central exterior surface major diameter of shell, has through spy there are two corresponding protruding ring between transmission shaft inside housings
Three line spiral bars made of different Milling Machining, the outer surface centre welding-on wear-resistant strip of spiral bar, both sides hardfacing alloy material.Under shell
End is limited on transmission shaft by simultaneously cap.
The invention has the following beneficial effects: the outer surface both sides hardfacing alloy material of three line spiral bars of housing outer surface,
The inner surface of the prolonged milling scraping deformed casing of energy, three line spiral bars are uniformly distributed, and welding-on is wear-resisting among outer surface
Band plays righting stabilization in casing, and the effective length of three line spiral bars reaches 650mm, greatly increases the stability of drilling rod.
Detailed description of the invention
Attached drawing is half sectional view of the invention:
1, shell 2 and cap 3, transmission shaft in figure
4, protruding ring 5, wear-resistant strip 6, alloy material
Specific embodiment
With reference to the accompanying drawing, the invention will be further described: as it is shown in the figures, the casing scraping centralizer includes shell
Body 1,1 set of the shell outside in transmission shaft 3, and two corresponding protruding rings are set between the inside of shell 1 and transmission shaft 3
4, at the central exterior surface major diameter of shell 1, have through three line spiral bar made of special Milling Machining, in the outer surface of three line spiral bars
Between welding-on wear-resistant strip 5, both sides hardfacing alloy material 6, the lower end of shell 1 by and cap 2 be limited on transmission shaft 3, in actual use, use
Drilling rod connects scraping righting stabilizer, is lowered into predetermined position in well, starts drilling machine, and rotary drill rod drives scraping righting to stablize
The transmission shaft 3 of device rotates together, and when protruding ring turns to certain angle, the salient point of protruding ring is recessed in the inside of shell 1, band
Dynamic shell 1 rotates together, and the alloy material 6 of built-up welding and the internal surface of sleeve pipe of deformation are sent out on three line spiral bars of 1 outer surface of shell at this time
Raw friction after milling, inverts drilling rod so that the inner surface of milling scraping deformed casing, reaches milling purpose, protruding ring
Salient point leaves the inside of shell 1, and salient point is recessed in the inside of transmission shaft 3, rotates drilling rod at this time, shell 1 is no longer with transmission shaft 3 one
Rotation is played, the inner surface of welding-on wear-resistant strip 5 and casing is played and helped there are very little gap on three line spiral bars of 1 outer surface of shell
Positive interaction, and the effective length of three line spiral bars reaches 650mm, greatly increases the stability of drilling rod, improves construction operation progress.
