Abstract
The utility model discloses a releasable borehole operation salvage device. The salvage device comprises an upper connector, an upper ball joint, a righting block, a salvage rod, a salvage hook and a photosensitive camera. The upper ball joint is arranged in an inner cavity of the upper connector, the upper ball joint and the upper end of the salvage rod are welded through electrowelding, the righting block, the salvage hook and the photosensitive camera are arranged on the salvage rod, a clamping device is further arranged on the lower portion of the righting block, the salvage hook is hinged to the lower portion of the salvage rod, two pulleys are arranged in the bottom end of the salvage rod, and two steel wire ropes are wound around the two pulleys respectively and are connected to the salvage hook. The releasable borehole operation salvage device has the advantages that cables falling in a petroleum well can be salvaged efficiently and visually through the device and will not fall off in the ascending process, repeated salvage is avoided, time and labor are saved, the ropes can be released when needing to be released, and it is avoided that accidents are more complex because the ropes are stuck and can not be released.
Description
Technical field
The utility model relates to petroleum machinery technical field, particularly relates to reversible underground work fisher.
Background technology
At present, known technology is in oil well cable salvage process, typically uses interior hook or steel plate hook the cable falling under oil well is salvaged to operation, and its major defect is: the fishing success ratio of interior hook is low, the cable of fishing for is difficult for clamping, clamping device is not set, when recovery hook hooks cable, in the process of up carrying, due to machinery or manually loosening, fishing rod can upper and lowerly rock and cause cable to come off, and need to again salvage, and wastes time and energy; Having is exactly that existing crowfoot is divided into dead hook and the hook of living again, but dead hook and the hook crowfoot of living are all reversible crowfoots not.In the time salvaging wire rope, cable, use can not be moved back crowfoot and be had certain risk, once junk is stuck, unfreezing is unsuccessful, and what must cause the accident is further complicated.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides reversible underground work fisher, and fisher can step up cable, steel wire etc., can also back off cable, steel wire.
The technical scheme that the utility model adopts is: reversible underground work fisher, comprise top connection, upper bulb, wiper block, fishing rod, recovery hook, sensitization camera composition, at the inner chamber of top connection, bulb is set, the upper end electric welding of upper bulb and fishing rod, wiper block, recovery hook and sensitization camera are set on fishing rod, the bottom of described wiper block is also provided with clamping device, described recovery hook is hinged on the bottom of fishing rod, the inside, bottom of fishing rod is also provided with two pulleys, and two wire rope are walked around respectively two pulleys and connected recovery hook.
As the preferred embodiment of this programme, described clamping device comprises the spring that is arranged on wiper block bottom, is arranged on baffle ring and the locking button of spring end.
As the preferred embodiment of this programme, described locking button is electric remote control locking button, being inwardly arranged in fishing rod of external extension.
As the preferred embodiment of this programme, the length that described locking button stretches out is slightly larger than the internal diameter of baffle ring.
As the preferred embodiment of this programme, two described wire rope all extend through bulb from the inside of fishing rod.
Compared with prior art, the beneficial effects of the utility model are: adopt this device be able to efficient, visual salvaging fall into the cable in oil well, and cable can not come off in the process rising, avoid repeating salvaging, save time and manpower, when also decontroling at any time, avoid stuck in the time that needs are decontroled rope, unfreezing is unsuccessful, and what cause the accident is further complicated.
Brief description of the drawings
In order to be illustrated more clearly in the technical solution of the utility model, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structure chart of the present utility model.
In figure: 1. top connection, 2. go up bulb, 3. wiper block, 4. fishing rod, 5. recovery hook, 6, sensitization camera, 7, spring, 8, baffle ring, 9, locking button, 10, pulley, 11, wire rope.
Detailed description of the invention
In order more clearly to understand the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further illustrated.
Reversible underground work fisher top connection 1 as shown in Figure 1, upper bulb 2, wiper block 3, fishing rod 4, recovery hook 5, sensitization camera 6 forms, 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 the fishing rod middle part of the pit shaft in oil well shaft core position all the time, the effect of recovery hook 5 is to hook the cable that falls into down-hole, the effect of sensitization camera 6 is the salvaging situations of observing at any time downhole cable by ground, the effect of top connection 1 is to be connected with top handling tubing string, while carrying out fishing, utilize 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 falling 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 salvaging process.The bottom of wiper block 3 is also provided with clamping device, clamping device comprises the spring 7 that is arranged on wiper block 3 bottoms, be arranged on baffle ring 8 and the locking button 9 of spring 7 ends, described locking button is electric remote control locking button, inwardly being arranged in fishing rod of external extension, the length that locking button stretches out is slightly larger than the internal diameter of baffle ring 8, can block or decontrol like this spring 7, the vertical distance that the internal diameter of described baffle ring 8 is slightly less than recovery hook 5 and stretches out fishing rod 4, can clamp like this cable hooking, make its difficult drop-off; Recovery hook 5 is hinged on the bottom of fishing rod 4, the inside, bottom of fishing rod 4 is also provided with two pulleys 10, two wire rope 11 are walked around respectively two pulleys 10 and are connected recovery hook 5, two wire rope 11 all extend through bulb 2 from the inside of fishing rod 4, outside can promote, puts down, fix wire rope, in the time will abandoning salvaging, and absent-mindedness wire rope 11, recovery hook 5 keeps flat downwards, decontrols cable wire rope etc.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
