Abstract
The utility model discloses a large-borehole butt-buckling fishing assembly, which solves the problems that a traditional fishing tool is difficult to butt-buckle when fishing fishes, inconvenient to operate, time-consuming and labor-consuming. The technical scheme includes that the fishing tool comprises a fishing tool, a composite joint and a fishing sleeve, wherein the upper end of the composite joint is a drilling tool joint, the lower end of the composite joint is detachably connected with the fishing tool, and the upper end of the fishing sleeve is sleeved on the middle section of the composite joint; the upper section of the salvaging sleeve is a reducing section, and the lower section of the salvaging sleeve is an expanding section. The utility model has the advantages of extremely simple structure, quick buckling, convenient salvage, easy operation, maintenance and disassembly and improvement of the salvage operation efficiency.
Description
Technical Field
The utility model relates to an in-well fishing tool, in particular to a large-well butt-buckling fishing assembly.
Background
At present, the borehole sizes of partial five-open-system structure wells are 660.4mm and 444.5mm, the borehole diameter is more than twice of the outer diameter of a drilling tool joint, a drilling tool buckle is attached to the borehole wall after being disconnected, the drilling tool buckle cannot be concentric, the buckling is difficult, and the difficulty in fishing the fallen fish is high. In the traditional fishing process, the fishing tool is lifted and lowered, and the rotary disc is rotated, so that the fishing tool is not easy to buckle and wastes time and labor.
Disclosure of Invention
The utility model aims to solve the technical problems and provides a large-borehole buckling fishing assembly which is extremely simple in structure, can be quickly buckled, is convenient to fish, is easy to operate, maintain and disassemble and improves the fishing operation efficiency.
The technical scheme includes that the fishing tool comprises a fishing tool, a composite joint and a fishing sleeve, wherein the upper end of the composite joint is a drilling tool joint, the lower end of the composite joint is detachably connected with the fishing tool, and the upper end of the fishing sleeve is sleeved on the middle section of the composite joint; the upper section of the salvaging sleeve is a reducing section, and the lower section of the salvaging sleeve is an expanding section.
The lower end of the salvaging sleeve is provided with a guide shoe.
The lower end of the composite joint is in threaded connection with a fishing tool.
The upper end of the salvaging sleeve is connected with the middle section of the composite joint through a screw.
The lower end of the fishing tool is positioned in the upper section of the diameter expanding section or the lower section of the diameter reducing section in the fishing sleeve.
Has the advantages that:
according to the fishing tool, the drilling tool, the fishing tool and the fishing sleeve are respectively connected into a whole by using the composite joint, the fishing tool is arranged in the fishing sleeve, the guide shoe can be used for pulling the fallen fish into the fishing sleeve, the fishing sleeve with larger space is used for positioning and guiding the fallen fish, and the concentricity is increased. The upper section of the salvaging sleeve is a reducing section, and the lower section of the salvaging sleeve is an expanding section, so that the salvaging sleeve can better limit and guide the buckling operation, the salvaging tool in the salvaging sleeve can be quickly buckled with the fallen fish, the difficulty of salvaging operation is greatly reduced, and the operating efficiency is improved; the composite joint, the drilling tool, the fishing tool and the fishing sleeve are detachably connected, so that components with different sizes or structures can be conveniently configured or replaced, the composite joint is also favorable for maintenance and disassembly, and the composite joint is particularly suitable for fishing of fish in a large borehole.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
Wherein, 1-composite joint, 2-fishing tool, 3-fishing sleeve, 3.1-guide shoe, 3.2-reducing section and 3.3-expanding section.
Detailed Description
The utility model is further explained below with reference to the drawings in which:
referring to fig. 1, the upper end of the composite joint 1 is a drill joint (e.g., a female buckle end) for connecting a drill or a jar, the lower end thereof can be a male buckle end, and is detachably connected (e.g., screwed) with a fishing tool 2, and the upper end of a fishing sleeve 3 is sleeved on the middle section of the composite joint 1 in a screwed manner; the upper section of salvaging sleeve 3 is reducing section 3.2, and the hypomere is expanding section 3.3, and the lower extreme is equipped with guide shoe 3.1, preferentially, the lower extreme of salvaging tool 2 is located the upper section of expanding section 3.2 or the hypomere region of reducing section 3.1 in salvaging sleeve 3, more do benefit to the direction of fish and do benefit to the make-up of fish and salvaging tool 2.
When the fishing tool is used, the two ends of the composite joint 1 are respectively connected with the drilling tool and the fishing tool 2, and then the upper end of the fishing sleeve 3 is sleeved (connected through threads) on the middle section of the composite joint 1. The assembly is arranged in a large borehole, so that the guide shoe 3.1 on the fishing sleeve 3 is beneficial to poking the fallen fish into the fishing sleeve 3, and then the fishing tool 2 is quickly buckled with the fallen fish, the operation is simple and convenient, and the operation efficiency is high.
Claims (5)
