Abstract
The utility model provides a rubber collector in pit. Relates to the technical field of oil field downhole tools. The lower part of the central tube is in threaded sealing connection with a sealing sleeve, a piston is arranged between the sealing sleeve and the central tube, the upper part of the piston is provided with a spacer ring and a rubber cylinder, the rubber cylinder is abutted against a step at the lower part of the upper joint, and the central tube is provided with a liquid inlet hole at the position of the piston. The utility model discloses following beneficial effect has: this if meet the rubber of scattering under the in-process of going into, the rubber can be hung on the peg, when going into the settlement position down, to suppress and keep pressure in the tubular column, hydraulic pressure promotes the piston and rises, it rises to promote the spacer ring, the packing element warp the inflation, the laminating of packing element external diameter forms a tray at the inside pipe wall of sleeve, lift the tubular column, collect the broken rubber in the way and carry out the well head, the steel thorn can pierce through the rubber, make the rubber can not drop again from the gap of packing element and sleeve pipe, the permanent magnetism ring that sets up in the fishing cap makes fishing cap, the peg has magnetism, adsorb the iron piece that meets along the way.
Description
The technical field is as follows:
the utility model belongs to the technical field of the oil field instrument in the pit and specifically relates to rubber collector in pit.
Background art:
in the prior art, in the process of drilling and workover operations, the rubber of fragments such as extruded and broken rubber of a rubber barrel of a packer and a bridge plug downhole tool is often left in the well, and the rubber needs to be cleaned up to ensure the normal construction of the next operation.
The utility model has the following contents:
the to-be-solved problem of the utility model is to provide an underground rubber collector, especially be fit for the user and clear up the piece rubber in the pit.
The technical scheme of the utility model is that: the underground rubber collector comprises an upper joint, a central pipe is arranged on the lower side of the upper joint, the lower portion of the central pipe is in threaded sealing connection with a sealing sleeve, a piston is arranged between the sealing sleeve and the central pipe, a spacer ring and a rubber cylinder are arranged on the upper portion of the piston, the rubber cylinder abuts against a step on the lower portion of the upper joint, and a liquid inlet hole is formed in the central pipe corresponding to the piston.
The lower part of the sealing sleeve is provided with a fishing cap, the diameter of the fishing cap is smaller than that of the rubber sleeve, and the outer side of the fishing cap is fixedly connected with hanging rods which are uniformly distributed on the circumference and incline upwards.
The inner hole of the salvaging cap is provided with a permanent magnetic ring, and the bottom of the salvaging cap is provided with a conical head.
Steel thorns which are uniformly distributed on the circumference are fixed on the upper side of the rubber cylinder in a vulcanization way.
The utility model discloses following beneficial effect has: connecting the rubber collector in the pit on the tubular column and going into in the pit, if meet the rubber that scatters under the in-process of going into down, the rubber can be hung on the peg, when going into the settlement position down, suppress and keep pressure in to the tubular column, hydraulic pressure promotes the piston and rises, promote the spacer ring and rise, the packing element warp the inflation, the laminating of packing element external diameter forms a tray at the intraductal wall of cover, lift the tubular column, collect the broken rubber along the way and carry out the well head, the steel thorn can pierce through the rubber, make the rubber can not drop again from the gap of packing element and sleeve pipe, the permanent magnetism ring that sets up in the salvage cap makes salvage cap, the peg has magnetism, adsorb the iron piece that meets along the way.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-an upper joint, 2-a central pipe, 3-a sealing sleeve, 4-a piston, 5-a liquid inlet hole, 6-a spacer ring, 7-a rubber cylinder, 8-a steel thorn, 9-a fishing cap, 10-a hanging rod, 11-a permanent magnet ring and 12-a conical head.
The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings:
as shown in figure 1, the underground rubber collector comprises an upper joint 1, wherein a central pipe 2 is arranged on the lower side of the upper joint 1, the lower portion of the central pipe 2 is in threaded sealing connection with a sealing sleeve 3, a piston 4 is arranged between the sealing sleeve 3 and the central pipe 2, a spacer ring 6 and a rubber cylinder 7 are arranged on the upper portion of the piston 4, the rubber cylinder 7 abuts against a step on the lower portion of the upper joint 1, and a liquid inlet hole 5 is formed in the central pipe 2 corresponding to the piston 4.
The lower part of the sealing sleeve 3 is provided with a fishing cap 9, the diameter of the fishing cap 9 is smaller than that of the rubber sleeve 7, and the outer side of the fishing cap 9 is fixedly connected with hanging rods 10 which are uniformly distributed on the circumference and incline upwards and outwards.
A permanent magnet ring 11 is arranged in an inner hole of the fishing cap 9, and a conical head 12 is arranged at the bottom of the fishing cap 9 and is helpful for penetrating through a rubber sheet to move downwards.
Steel pricks 8 which are evenly distributed on the circumference are fixed on the upper side of the rubber cylinder 7 in a vulcanization way.
Connecting the rubber collector in the pit on the tubular column and going into in the pit, if meet the rubber that scatters under the in-process of going into down, the rubber can be hung on peg 10, when going into the settlement position down, suppress and keep pressure in the tubular column, hydraulic pressure promotes piston 4 and rises, promote spacer ring 6 and rise, packing element 7 warp the inflation, 7 external diameter laminating of packing element form a tray at the intraductal wall of cover, lift the tubular column, collect the broken rubber along the way and carry out the well head, steel thorn 8 can pierce through the rubber, make the rubber can not drop again from packing element 7 and sheathed tube gap, the permanent magnetism ring 11 that sets up in salvage cap 9 makes salvage cap 9, peg 10 have magnetism, adsorb the iron piece that meets along the way.
