Detailed description of the invention
The utility model provides a kind of rope salvaging device, is applied in oil well, is salvaging test cable or is dragging in the process of oily steel wire, can greatly reduce test cable or drag for the cut-off probability of oily wire rope, fishing success ratio is improved.
The utility model provides a kind of rope salvaging device, be applied in oil well, see Fig. 1, comprise support 1, recovery hook 2 and tubing coupling 5, recovery hook 2 is fixed on support bar 1, for hooking the rope in described oil well, tubing coupling 5 is arranged on the upper end of support bar 1, and be connected with the bottom of the tubing string in described oil well, the upper section of recovery hook 2 is inclined-plane, makes can not cause cutting when salvaging test cable or dragging for oily wire rope, so, can greatly reduce test cable or drag for the cut-off probability of oily wire rope, fishing success ratio is improved.
Wherein, described rope can be such as test cable, drag for oily wire rope etc., recovery hook 2 is specially cylinder or Elliptic Cylinder, when making described rope be wrapped on recovery hook 2, because recovery hook 2 is cylinder or Elliptic Cylinder, make the contact surface of described rope and recovery hook 2 more smooth, corner angle are less, guarantee further can not cause cutting when salvaging described rope, so, test cable can be reduced further or drag for the cut-off probability of oily wire rope, improve fishing success ratio further.
Specifically, support bar 1 is straight-bar, can be such as steel, straight-bar made of iron, certainly, support bar 1 is the main body of described rope salvaging instrument, needs to select comparatively large gauge to bear load to have higher-strength, therefore, support bar 1 specifically can select sucker rod, lower mask body for support bar 1 for sucker rod.
Concrete, recovery hook 2 is welded on sucker rod 1, and recovery hook 2 and sucker rod 1 angle are upwards 15 degree, recovery hook 2 can form for comparatively small-sized sucker rod blocks, what make the contact surface of recovery hook 2 and rope does not have corner angle, and two sections up and down of recovery hook 2 are all parallel cuts into oblique profile, top section forms wedge angle, realization can not cause cutting when fishing for rope class junk, bottom section becomes 15 degree of angles integrally welded with described sucker rod, and multiple recovery hook 2 is spaced apart in an angle of 90 degrees from bottom to top along described sucker rod, make recovery hook 2 easierly can hook described rope, and recovery hook 2 is specially cylinder or Elliptic Cylinder, make the contact surface of described rope and recovery hook 2 more smooth, corner angle are less, guarantee further can not cause cutting when salvaging described rope, so, the probability that described rope is cut-off can be reduced further, further raising fishing success ratio.
Concrete, described rope salvaging device also comprises anti-channeling pressure cap 3, is provided with a through hole, by described through hole and described sucker rod affixed, anti-channeling pressure cap 3 is arranged between recovery hook 2 and tubing coupling 5.
Concrete, the cross section of anti-channeling pressure cap 4 is circular, the described through hole of anti-channeling pressure cap 3 is passed on the top of described sucker rod, be integrated by being welded to connect, make in the process hooking described rope, described rope can not be crossed anti-channeling pressure cap 4 and be intertwined with tubing coupling 5 or described tubing string, thus can be reduced in hook in described rope process occur top alter the probability causing blocking accident, further raising fishing success ratio, wherein, the diameter of anti-channeling pressure cap 4 is less than the diameter of described oil well, can work to make described rope salvaging device in described oil well.
Concrete, described rope salvaging device also comprises plug 4, and the top of lower end and described sucker rod is affixed, and upper end is connected with tubing coupling 5.
Concrete, the upper end of plug 4 is provided with screw thread, by described screw thread by plug 4 screwed connection tubing coupling 5, so, by described screw thread plug 4 can be connected with tubing coupling 5 more firm.
Concrete, described sucker rod, anti-channeling pressure cap 3, plug 4 and tubing coupling 5 are coaxial, with by rotating described rope salvaging device, make described rope be wrapped on described rope salvaging device with this, conveniently salvage described rope.
In actual application, when using described rope salvaging device, tubing coupling 5 is connected to the bottom of described tubing string, and be lowered in oil well casing, make anti-channeling pressure cap 3 with lower portion intert enter coiling be deposited in the rope of sleeve bottom, by recovery hook 2 rope is firmly linked with after rotating described tubing string certain angle and on carry, rope in well is successfully salvaged well.
By an embodiment or multiple embodiment, the utility model has following beneficial effect or advantage:
One, due to the rope salvaging device in the embodiment of the present application, be applied in oil well, recovery hook is fixed on support bar, for hooking the rope in described oil well, tubing coupling is arranged on the upper end of described support bar, and be connected with the bottom of the tubing string in described oil well, the upper section of described recovery hook is inclined-plane, upper section due to described recovery hook is inclined-plane, make can not cause cutting when salvaging test cable or dragging for oily wire rope, so, can greatly reduce test cable or drag for the cut-off probability of oily steel wire, fishing success ratio is improved.
Two, because the cross section of the anti-channeling pressure cap in the embodiment of the present application is circular, the described through hole of anti-channeling pressure cap is passed on the top of described sucker rod, be integrated by being welded to connect, make in the process hooking described rope, described rope can not be crossed anti-channeling pressure cap and tubing coupling or described tubing string and be intertwined, thus can be reduced in hook in described rope process occur top alter the probability causing blocking accident, improve fishing success ratio further.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.Apparent, defined herein General Principle will be made for those skilled in the art when not departing from the spirit or scope of utility model, can to realize in other embodiments the multiple amendment of these embodiments.Therefore, the utility model can not be limited and these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and novel features.
