Abstract
The utility model relates to a well service tool, in particular to a guide shoe quickly-mounting adapter. The technical scheme is that the guide shoe quickly-mounting adapter mainly comprises an upper connector, a centralizing body, a large-diameter outer thread, a small-diameter thread and a tube body. The upper end of the tube body is connected with the upper connector, the lower end of the tube body is provided with the large-diameter outer thread and the small-diameter thread, and the middle of the tube body is provided with the centralizing body. The guide shoe quickly-mounting adapter has the advantages of being capable of quickly switching a downhole tool suitable for a five-cun-half sleeve into a tool suitable for a 7' sleeve or a sleeve with an even larger diameter, convenient to install, and capable of improving working efficiency of well service only requiring a reducer union capable of adapting to sleeves with different diameters.
Description
Technical field:
The utility model relates to a kind of workover treatment instrument, particularly a kind of guide shoe crossover sub that installs additional fast.
Background technology:
At present, in the oil well repairing operation, when in 7 cun sleeve pipes, salvaging junk; If the fishing tool that the operator has only 5 cun half-covering tubes to use generally is the guide shoe tube of fishing tool external welding that uses at 5 cun half-covering tubes, the problem of its existence is: when workover treatment, weld; Promptly waste time and energy; The unstable risk of welding is arranged again, the guide shoe tube is dropped in the well, cause big loss.
Summary of the invention:
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of guide shoe crossover sub that installs additional fast is provided, and can adapt to the sleeve pipe of different inner diameters, and it is easy for installation, can improve operating efficiency.
Its technical scheme is: mainly be made up of top connection, centralizer body, major diameter external screw thread, minor diameter external screw thread and body, the upper end of described body connects top connection, and the lower end is provided with major diameter external screw thread and minor diameter external screw thread, and the centre is provided with centralizer body.
Above-mentioned major diameter external screw thread and guide shoe tube flexibly connect.
The beneficial effect of the utility model is: the following well tool that certain 51/2 〞 sleeve pipe is suitable for converts the instrument that adapts to 7 〞 sleeve pipes even the use of larger diameter sleeve pipe fast to; And it is easy for installation; Can improve operating efficiency; During use, the reducer union that only need carry the sleeve pipe that can adapt to different-diameter gets final product, and improves workover treatment efficient greatly.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is sketch mapes of the guide shoe tube of the utility model;
Among the last figure: top connection 1, centralizer body 2, major diameter external screw thread 3, minor diameter external screw thread 4 and body 5, guide shoe tube 6.
The specific embodiment:
In conjunction with accompanying drawing 1-2, the utility model is done further to describe:
The utility model mainly is made up of top connection 1, centralizer body 2, major diameter external screw thread 3, minor diameter external screw thread 4 and body 5; The upper end of described body 5 connects top connection 1; The lower end is provided with major diameter external screw thread 3 and minor diameter external screw thread 4; The centre is provided with centralizer body 2, and major diameter external screw thread 3 flexibly connects with guide shoe tube 6.
During use, the following well tool that certain 5 cun half-covering tubes are suitable for converts to fast and adapts to 7 cun sleeve pipes even larger diameter sleeve pipe, and the reducer union that only need carry the sleeve pipe that can adapt to different-diameter gets final product, and improves workover treatment efficient greatly.
