Abstract

A salvaging device of cables under an oil well comprises an upper joint (1), an upper ball joint (2), a wiper block (3), a salvaging rod (4), a salvaging hook (5) and a photographic camera (6) and is characterized in that the upper ball joint (2) is arranged in an inner chamber of the upper joint (1); the upper ball joint (2) is in welding connection with the upper end of the salvaging rod (4) through electric welding; and the salvaging rod (4) is provided with the wiper block (3), the salvaging hook (5) and the photographic camera (6). The wiper block (3) is used for keeping the salvaging rod (4) always at an axis position of the middle of a shaft of the oil well; the salvaging hook (5) is used for tightly hooking the cables falling under the well; the photographic camera (6) is used for observing salvage conditions of underground cables through the ground at any time; and the upper joint (1) is used for connecting with a lifting pipe column which is arranged on the upper portion. The salvaging device of the cables under the oil well has the advantage of being capable of efficiently and measurably salvaging the cables falling into the oil well.

Description

Cable salvage device under a kind of oil well

Technical field

The utility model relates to the petroleum machinery technical field, especially relates to cable salvage device under a kind of oil well.

Background technology

At present, known technology is in oil well cable salvage process, typically uses interior hook or steel plate hook the cable that falls under oil well is salvaged operation, and its major defect is: the fishing success ratio of interior hook is low, the cable of fishing for is difficult for chucking, wastes time and energy; Steel plate hook easily causes the generation of lock of tool drilling

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides cable salvage device under a kind of oil well, this application of installation in the fishing construction of oil downhole cable, can be improved the success rate of salvaging the downhole cable construction, effectively prevent the generation of lock of tool drilling.

the technical scheme that its technical problem that solves the utility model adopts is: adopt cable salvage device under a kind of oil well, this device has top connection, upper bulb, wiper block, fishing rod, recovery hook, the sensitization camera forms, it is characterized in that: at the inner chamber of top connection, bulb is set, the upper end electric welding of upper bulb and fishing rod, wiper block is set on fishing rod, recovery hook and sensitization camera, the effect of wiper block is to keep fishing rod to be in all the time the pit shaft middle part shaft core position of oil well, the effect of recovery hook is to hook the cable that falls into the down-hole, the effect of sensitization camera is the salvaging situation of downhole cable of observing at any time by ground, the effect of top connection 1 is to be connected with top handling tubing string, utilize this device can be efficient, visual salvaging falls into the cable in oil well.

The beneficial effects of the utility model: by field trial, the utility model compared with prior art adopts this device efficient, visual salvaging to fall into the interior cable of oil well, and can effectively prevent the generation of lock of tool drilling in the salvaging process.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated:

Fig. 1 is the structural representation of cable salvage device under a kind of oil well.

In Fig. 1: 1. top connection, 2. go up bulb, 3. wiper block, 4. fishing rod, 5. recovery hook, 6 sensitization cameras.

The specific embodiment:

in Fig. 1, under oil well, the cable salvage device is that top connection 1 is arranged, upper bulb 2, wiper block 3, fishing rod 4, recovery hook 5, sensitization camera 6 forms, it is characterized in that: at the inner chamber of top connection 1, bulb 2 is set, the upper end electric welding of upper bulb 2 and fishing rod 4, wiper block 3 is set on fishing rod 4, recovery hook 5 and sensitization camera 6, the effect of wiper block 3 is to keep fishing rod to be in all the time the pit shaft middle part shaft core position of oil well, the effect of recovery hook 5 is to hook the cable that falls into the down-hole, the effect of sensitization camera 6 is the salvaging situations of downhole cable of observing at any time by ground, the effect of top connection 1 is to be connected with top handling tubing string, when carrying out fishing, utilize the top tubing string that this device is sent into appropriate location in oil well, then utilize this device to carry out fishing to the cable that falls in oil well, utilize this device can be efficient, visual salvaging falls into the cable in oil well, and can effectively prevent the generation of lock of tool drilling in the salvaging process.
