Abstract

The utility model discloses a spring salvage tube for a pillar body, and a tubular body falling into a well in an oilfield. In the salvage tube 1, a bracket ring 8 to fix a cone central passage, a plurality of elastic rings 6, and on the elastic ring, a pressure ring 2 connected by screw are arranged. In the perimeter direction of each ring piece, a plurality of uniformly distributed through holes (7, 5, 4) in axial direction are arranged. A passageway path on the elastic ring can form serial products, while in use, according to the size, weight of junks, assembling can be chosen, and the junks can be treated in time.

Description

Spring salvage tube

The utility model relates to a kind of elasticity fishing socket that the oil field falls into post in the well, tubular body.

The oil field falls into the fish accident of post in the well, tubular body in processing, often adopts the sleeve body upside instrument of windowing to beat, and needs according to junk specification design fishing tool; As not quite clear to junk, influence the carrying out of salvaging just, according to this because of proposing the design.

The purpose of this utility model is to overcome shortcoming part in the above-mentioned prior art, and provides a kind of at the serial elastic ring fishing socket of fishing socket Rigen according to needs and easy installation.

The purpose of this utility model can reach by the following technical programs: be fixed with the filler ring of conical centre's passage, a plurality of elastic ring in fishing socket, the pressure ring that is threaded is arranged on the elastic ring, upwards there are a plurality of uniform axially extending bores in each ring week.

Can the be threaded fishing socket short circuit of wall mouth of the lower end of above-mentioned fishing socket has splayed flexure strip inwards on the short circuit wall mouth.

The utility model has following effect compared to existing technology: can assemble fishing socket as required, make junk in time obtain handling favourable production.

Fig. 1 is the utility model complete section structure chart;

Fig. 2 is Fig. 1 vertical view;

Fig. 3 is filler ring 8 usefulness screws 10 assembly drawings on Fig. 1;

Fig. 4 is short circuit 12 structure charts that fishing socket 1 lower end can be threaded on Fig. 1.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

Be connected on 1 li filler ring 8, a plurality of elastic ring 6 that is fixed with tapered channel of fishing socket on the drilling tool, wherein filler ring 8 can be used guide shoe 9 internal projecting rings that connected or with screw 10 assemblings; Have on the elastic ring 6 with fishing socket in the pressure ring 2 that is threaded rotatably compress fixingly, upwards there are a plurality of uniform axially extending bores (7,5,4) in each ring (8,6,2) week; Formed central passage forms awl, post passage from bottom to top.

For improving fishing success ratio, the fishing socket short circuit 12 of the wall mouth 13 that can be threaded in the lower end of fishing socket has splayed flexure strip 11 inwards on the short circuit wall mouth, can be many to symmetrical flexure strip.Wherein elastic ring 6 is made by rubber.

The specification of each ring can form series of products in the fishing socket, and wherein the quantity of elastic ring can be selected assembling according to trouble of lost tool in hole specification, weight.On top of fish in the drilling tool lower going-into-well, the moving drilling tool of turn on pump circulation slow-speed is introduced junk in the guide shoe with dialling hook on the guide shoe, continues to bore down, snaps in the fishing socket when pump pressure raises and holds a period of time explanation junk, can pull out of hole.

Claims

1, a kind of oil field that is used for falls into post in the well, tubular body elasticity fishing socket, it is made up of fishing socket 1 and the guide shoe 9 that is threaded, it is characterized in that: the filler ring 8, a plurality of elastic ring 6 that in fishing socket, are fixed with conical centre's passage, the pressure ring 2 that is threaded is arranged on the elastic ring, upwards there are a plurality of uniform axially extending bores (7 in ring (8,6,2) week, 5,4).

2, elasticity fishing socket as claimed in claim 1 is characterized in that: the fishing socket short circuit 12 of the wall mouth 13 that can be threaded in the lower end of fishing socket 1 has splayed flexure strip 11 inwards on the short circuit wall mouth.

3, elasticity fishing socket as claimed in claim 1 is characterized in that: filler ring 8 can be assembled with bulge loop support in the fishing socket or with screw 10.
