Abstract
The utility model relates to a down -hole junk fishing barrel belongs to oil field workover smallclothes, rope type junk fishing tool technical field. By top connection, cover mill a section of thick bamboo, the washing pipe constitutes, the top connection is milled through screw thread and cover and tin is connected, overlaps to mill to be equipped with gullet tooth on the barrel lower part inner wall, washing pipe upper end is connected through screw and top connection and is installed in the cover mills a cavity, and the washing pipe mills with the cover on the pipe wall outward and is equipped with gullet tooth on the position that barrel inner wall lower part is corresponding. The beneficial effects of the utility model are that milling a section of thick bamboo, nib effective combination through the cover, utilizing wire rope's elasticity characteristic simultaneously, guarantee that the smallclothes junk gets into the barrel, the loose -leaf baffle is fixed the smallclothes junk in the barrel, and gullet tooth drags for a rope type junk, and convenient operation realizes that sand washing, cover mill, salvage and once accomplish, has improved salvage efficiency, has practiced thrift the operating cost.
Description
Technical field
The utility model relates to a kind of downhole falling object catch sleeve, belongs to oil well repairing operation smallclothes, rope class falling object fishing tool technical field.
Background technology
Often there will be the smallclothes class junks such as paraffin scraper, valve ball and packing element fragment and cable, steel wire Luo Jing and sand bury the complex situations simultaneously occurred in underground work process; certain difficulty is brought to workover treatment; conventional operational method is first sand washing; apply salvaging of tackling all problems at once again and get smallclothes class junk; the rope class falling object fishing tools such as inner and outer hooks are finally utilized to pull cable, steel wire out; flow chart is loaded down with trivial details, increases labour intensity, adds operating cost.
Patent No. CN200920224628 discloses a kind of Multifunction fishing cylinder, be made up of top connection, cylindrical shell, zigzag internal thread and guide shoe, be provided with zigzag internal thread at the inner chamber of cylindrical shell, by rotating fishing socket, zigzag internal thread is rotated, thus the fishing junks such as rope class, rubber are gone out.But because its structure limits, run into shake out, complex hole condition that small falling object and rope class junk occur simultaneously, be difficult to realize disposable salvaging object.
Utility model content
The purpose of this utility model is to overcome the defect that above-mentioned salvaging operation of the prior art is loaded down with trivial details, salvage weak effect, providing a kind of high efficiency fishing tool, shorten the well workover time, reduce labor intensity.
The utility model is made up of top connection, casing section mill, washing pipe, and top connection is connected with casing section mill by screw thread, and casing section mill cylindrical shell lower inner wall is provided with briar tooth; Washing pipe upper end is mounted in casing section mill cavity by screw thread and top connection, and position corresponding with casing section mill cylinder inboard wall bottom on washing pipe outer tube wall is provided with briar tooth.
The beneficial effects of the utility model are: by casing section mill, nib efficient combination, utilize the elastic characteristic of wire rope simultaneously, ensure that small falling object enters cylindrical shell, small falling object is fixed in cylindrical shell by loose-leaf baffle plate, briar tooth drags for rope class junk, easy to operate, realizes sand washing, overlaps milling, salvaging once completes, improve salvaging efficiency, save operating cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
The utility model is made up of top connection 1, casing section mill 2, washing pipe 3, and top connection 1 is connected with casing section mill 2 by screw thread, and casing section mill 2 cylindrical shell lower inner wall is provided with briar tooth 7a; Washing pipe 3 upper end is mounted in casing section mill 2 cavity by screw thread and top connection 1, and washing pipe 3 outer tube wall bottom is provided with briar tooth 7b.
Described casing section mill 2 cylinder inboard wall top and washing pipe 3 outer tube wall are evenly equipped with steel wire 5a, 5b of mutually superposing.
Be provided with loose-leaf baffle plate 6 in the middle part of described casing section mill 2 cylinder inboard wall, can stop that small falling object falls well.
Described washing pipe 3 lower end is nib shape, makes washing pipe 3 easily enter small falling object inside.
Described top connection 1 body lower part has hydrophthalmia 4, ensures that well cleanout and reverse cleanout is unimpeded.
When Holes of Complicated Wells salvages junk, top connection 1 of the present utility model is connected with running string by screw thread, down to 1-2 rice above junk, turn on pump circulates, circulation fluid rinses through washing pipe 3 inner chamber and to remove in well the material such as cement and sand around junk, then, transfer tubing string pressurization, washing pipe 3 enters small falling object inside, small falling object is up under the effect of hydraulic blow, back down loose-leaf baffle plate 6, wire rope 5a, 5b enters casing section mill 2 top, rotate tubing string 5-7 circle, make small falling object at wire rope 5a, compacting under the elastic reaction of 5b, do not enter wire rope 5a, the small falling object of 5b is descending, stopped by loose-leaf baffle plate 6, cable, the rope such as steel wire class junk is by casing section mill 2 cylinder inboard wall, the briar tooth 7a of washing pipe 3 outer tube wall, 7b catches, sand washing can be realized, cover milling, fishing integrated, if washing pipe 3 lumen blockage, hydrophthalmia 4 by top connection 1 bottom sets up construction circulation canal, do not affect normal construction, method of operating is simple, fast effectively, ensure that salvaging efficiency.
