Abstract
The utility model relates to an explosive loop cable cutter for a oil and gas well, which mainly solves the problem of cutting off a cable at an appropriate position in the well, and is characterized in that the upper end and the lower end in an axial eccentric hole of a cylindrical cutter body (1) are respectively provided with an upper circular plug (2) and a lower circular plug (2); circular gunpowder (4) is arranged in a circular space between the upper plug (2) and the lower plug (3); energy collecting sleeves (5) are arranged in the upper plug (2), the lower plug (3) and the gunpowder (4) ring; the cable passes through the energy collecting sleeves (5); one side of the cutter body (1) is provided with a bypass hole (6) which is communicated with the gunpowder (4) in the eccentric hole; the upper end of the bypass hole (6) is connected with a connector (7); and a fuse which is connected with the gunpowder (4) passes through the connector (7) and the bypass hole (6). The explosive loop cable cutter for the oil and gas well can cut off the cable at the appropriate position.
Description
Technical field:
The utility model relates to processing accident used hawser cutter, especially gas under balance pressure drilling rotating blowout preventer in the oil reservoir logging field.
Background technology:
In oil reservoir logging or well workover field, often in well, transfer tester or workover tool by hawser, write as logger or well-repairing work.And in transferring process or political affairs when finishing, because the well inclement condition is stuck in tester or workover tool and can't takes out in the well, in order to take out hawser, need hawser be cut off at the hawser correct position, and require not injure its sleeve pipe on every side, and take out hawser, assurance well logging or well workover are proceeded.
The utility model content:
In order to solve the problem that correct position is cut off hawser in well, the utility model provides a kind of oil gas well with the explosion type hawser cutter that goes in ring, and this oil gas well can be cut off hawser at correct position with the explosion type hawser cutter that goes in ring.
The technical solution of the utility model is: this oil gas well comprises main body with the belt hawser cutter of explosion type, upper and lower side is equipped with annular upper plug head and annular lower end cap respectively in the axial eccentric orfice of cylinder-shaped body, annular space between upper plug head and the lower end cap is built-in with ring-type shape gunpowder, upper plug head, lower end cap and gunpowder ring are built-in with the cumulative cover, hawser passes in the cumulative cover, main body one side has the by-pass prot that communicates with gunpowder in the eccentric orfice, the by-pass prot upper end is connected with joint, is installed with the detonating fuse that links to each other with gunpowder in joint and the by-pass prot.
The utlity model has following beneficial effect: this oil gas well goes in ring the hawser cutter at first owing to adopt at body shaft annular space between upper plug head and the lower end cap in eccentric orfice and be built-in with ring-type shape gunpowder with explosion type, upper plug head, lower end cap and gunpowder ring are built-in with the cumulative cover, hawser passes in the cumulative cover, main body one side has the by-pass prot that communicates with gunpowder in the eccentric orfice, be installed with the detonating fuse structure that links to each other with gunpowder in the by-pass prot, after at the bottom of the lower going-into-well, utilize detonating fuse to detonate, the jet that formation is converged to central point cuts off cable, make cable obtain tripping out well head, reach the purpose of processing accident.This oil gas well can be cut off hawser at correct position with the belt hawser cutter of explosion type thus.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is Fig. 1 vertical views.
1-main body among the figure, 2-upper plug head, 3-lower end cap, 4-gunpowder, 5-cumulative cover, 6-by-pass prot, 7-joint, 8-detonating fuse.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, this oil gas well comprises main body 1 with the belt hawser cutter of explosion type, be threaded respectively annular upper plug head 2 and annular lower end cap 3 of upper and lower side in the cylinder-shaped body 1 axial eccentric orfice, be connected with cumulative cover 5 in upper plug head 2 and lower end cap 3 rings, annular sealed space between upper plug head 2 and lower end cap 3 outside the cumulative cover 5 is built-in with ring-type shape gunpowder 4, hawser passes in cumulative cover 5, main body 1 one sides have the by-pass prot 6 that communicates with gunpowder 4 in the eccentric orfice, by-pass prot 6 upper ends are connected with joint 7, are installed with the detonating fuse 8 that links to each other with gunpowder 4 in joint 7 and the by-pass prot 6.
Operating principle: this oil gas well is enclosed within on the hawser of tester or workover tool with the belt hawser cutter of explosion type, in the process of going into the well or after descending on earth, when tester or workover tool block, this oil gas well is cut and is lowered into the hawser correct position with the explosion type hawser that goes in ring, by detonating fuse 8 priming powders 4, the jet that converges to central point that gunpowder 4 forms cuts off cable, makes cable obtain tripping out well head, reaches the purpose of processing accident.
