Abstract
The utility model relates to a fishing tool, in particular to a multilevel guiding tube guiding shoe connector. According to the technical scheme, the multilevel guiding tube guiding shoe connector comprises a first casing joint, a second casing joint, guiding shoes, a drill rod short piece, a casing short piece and big and small joint ends, the first casing joint is connected to one end of the second casing joint through the casing short piece, and the other end of the second casing joint is connected with the guiding shoes through the big and small joint ends. The drill rod short piece is arranged in the casing short piece. The multilevel guiding tube guiding shoe connector has the advantages that the different guiding shoes are adopted according to different fish tops, then the corresponding big and small joint ends are matched, and not all the guiding shoes of the tools need to be enlarged, and only need to be replaced with guiding shoes with the corresponding size. In addition, the multilevel guiding tube guiding shoe connector can be connected with a conventional tool conveniently and retreat from the tool very conveniently after fishing, processing cost is saved, and field use is facilitated.
Description
Technical field
The utility model relates to a kind of fishing tool, particularly a kind of multistage skirt guide shoe joint.
Background technology
In the major diameter well in oil field during the junk such as fishing oil pipe, due to junk diameter and hole diameter poor very large (take d62mm oil pipe as example, the difference of its box cupling diameter and hole diameter is 135mm) the often very difficult top of fish that accurately finds of conventional guide shoe, careless manipulation, be easy to cause top of fish to be bent song, cause more complicated engineering accident; For fear of the problems referred to above, add large guide shoe just need to conventional instrument, can address this problem, but repeatedly salvage, often need each part instrument all to strengthen guide shoe, waste time and energy, and processing cost is also along with improve.Moreover, to the upper large guide shoe of individual tool processing, to salvage after junk, while exiting instrument, because the instrument of large guide shoe exists, the instrument that moves back is also very difficult.
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 multistage skirt guide shoe joint is provided, and can connect very easily conventional instrument, salvages backed off after random instrument also very convenient, has both saved processing cost, has facilitated again on-the-spot use.
Its technical scheme is: comprise the first casing coupling, the second casing coupling, guide shoe, drill pipe nipple, casing nipple, box cupling concentric reducer, the first described casing coupling is connected to one end of the second casing coupling by casing nipple, the other end of the second casing coupling connects guide shoe by box cupling concentric reducer; Described casing nipple inside is provided with drill pipe nipple.
Above-mentioned guide shoe and box cupling concentric reducer are provided with many groups.
The beneficial effects of the utility model are: according to different tops of fish, adopt different guide shoes, and then coordinate corresponding box cupling concentric reducer, thereby do not need each part instrument all to strengthen guide shoe, as long as change the guide shoe of corresponding size.In addition, can connect very easily conventional instrument, salvage backed off after random instrument also very convenient, both save processing cost, facilitate again on-the-spot use.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: the first casing coupling 1, the second casing coupling 2, guide shoe 3, drill pipe nipple 4, casing nipple 5, box cupling concentric reducer 6.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises the first casing coupling 1, the second casing coupling 2, guide shoe 3, drill pipe nipple 4, casing nipple 5, box cupling concentric reducer 6, the first described casing coupling 1 is connected to one end of the second casing coupling 2 by casing nipple 5, the other end of the second casing coupling 2 connects guide shoe 3 by box cupling concentric reducer 6; Described casing nipple 5 inside are provided with drill pipe nipple 4, connect fishing tool, certainly, can change according to varying in size of junk the fishing tool of different model.
Wherein guide shoe 3 and box cupling concentric reducer 6 are provided with many groups, according to different tops of fish, adopt different guide shoes, and then coordinate corresponding box cupling concentric reducer 6, thereby do not need each part instrument all to strengthen guide shoe, as long as change the guide shoe of corresponding size.In addition, can connect very easily conventional instrument, salvage backed off after random instrument also very convenient, both save processing cost, facilitate again on-the-spot use.
