Abstract
The utility model relates to a casing pipe repairing apparatus for oil well practice. The technical scheme of the casing pipe repairing apparatus is that the repairing apparatus comprises a main body, a cutter body supporting seat, a left blade, a baffle ring, screws and a right blade, wherein the upper and the lower sides of the main body are respectively provided with an upper cutter groove and a lower cutter groove; the baffle ring is fastened between the upper cutter groove and the lower cutter groove via the screws; the upper cutter groove and the lower cutter groove are fastened in the cutter body supporting seat; the left blade is fastened in the upper cutter groove; and the right blade is fastened in the lower cutter groove. The beneficial effects of the casing pipe repairing apparatus for oil well practice are that the casing pipe can be positively and negatively scraped via the left and the right blades fastened on the main body, so work efficiency is improved and scraping difficulty is reduced; and a cutter body supporting plate can be fastened by the baffle ring fastened in the middle of the main body.
Description
Technical field
The utility model relates to a kind of workover tool, particularly a kind of oil well operation casing repairing device.
Background technology
Casing scraper can be used for removing things such as remaining in the iron oxide that produces after cement block on internal surface of sleeve pipe, cement sheath, hard wax, various saline crystallization and deposit, perforation burr and sleeve pipe corrosion, to be lowered to various lower well tools unblockedly.Sleeve pipe scraping is flow chart conventional in oil field operation process, in the time carrying out operation, conventionally adopt casing scraper to carry out scraping, conventional scraper adopts unified cutter hub at present, can not realize the positive and negative scraping to cutter hub, also less to the scraping action power of sleeve pipe, particularly after the fouling of water injection well, scraping difficulty strengthens, inefficiency.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of oil well operation casing repairing device is provided.
Its technical scheme is: comprise main body, cutter hub supporting seat, left blade, baffle ring, screw, right blade, main body be provided with respectively up and down upper knife groove and lower knife groove, between described upper knife groove and lower knife groove, fix baffle ring by screw, the inner fixed cutter body supporting seat of described upper knife groove and lower knife groove, fixing left blade in described upper knife groove, fixing right blade in described lower knife groove.
Above-mentioned cutter hub supporting seat inside is provided with spring, and spring connects left blade and right blade.
The beneficial effects of the utility model are: realize the positive and negative scraping to sleeve pipe by fix left blade and right blade in main body, increase work efficiency, reduce scraping difficulty, can play the effect of fixed cutter body base plate by fixing baffle ring in the middle of main body, simple in structure, shaving effect is good, can effectively remove the dirt of internal surface of sleeve pipe, reaches the effect of cannula cleaning.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of cutter hub supporting seat;
In upper figure: main body 1, upper knife groove 2, lower knife groove 3, screw 4, baffle ring 5, cutter hub supporting seat 6, left blade 7, right blade 8, spring 9.
The specific embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises main body 1, upper knife groove 2, lower knife groove 3, screw 4, baffle ring 5, cutter hub supporting seat 6, left blade 7, right blade 8, main body 1 be provided with respectively up and down upper knife groove 2 and lower knife groove 3, between described upper knife groove 2 and lower knife groove 3, fix baffle ring 5 by screw 4, the inner fixed cutter body supporting seat 6 of described upper knife groove 2 and lower knife groove 3, the interior fixing left blade 7 of described upper knife groove 2, the interior fixing right blade 8 of described lower knife groove 3, left blade 7 and right blade 8 have reduced scraping difficulty, have improved operating efficiency.
Wherein, cutter hub supporting seat 6 inside are provided with spring 9, and spring 9 connects left blade 7 and right blade 8 springs plays the effect of effective supporting blade, accomplishes not damage sleeve pipe.
Realize the positive and negative scraping to sleeve pipe by fix left blade and right blade in main body, increase work efficiency, reduce scraping difficulty, can play the effect of fixed cutter body base plate by fixing baffle ring in the middle of main body, simple in structure, shaving effect is good, can effectively remove the dirt of internal surface of sleeve pipe, reaches the effect of cannula cleaning.
