Abstract
A rotary steel wire junk fishing tool relates to the technical field of auxiliary tools and comprises a strong magnetic suction piece, a hard hook, a soft hook, a spear and a rotating shaft; the hook body comprises a spear, a hard hook and a soft hook; a sharp lance is arranged at the top end of the hook body, a hard hook which is in an integral structure with the sharp lance is arranged at a position close to the sharp lance, and a strong magnetic suction piece is arranged on the inclined surface of the fishing hard hook; the soft hook is arranged on the lower half part of the hook body, the bottom end of the hook body is provided with an upper auxiliary hard hook a, and the upper auxiliary hard hook and the hook body are of an integrated structure; the rotating shaft and the hook body are fixedly installed through a rotating shaft positioning hole arranged on the lower half part of the hook body; the tail end of the rotating shaft is provided with a thread shape. The fishing tool not only solves the problems that the steel wire is not easy to be firmly grabbed and the steel wire group is easy to be blocked by the packer when being smashed into a hard group and lifted up in the current steel wire junk fishing process, but also saves manpower, improves the fishing success rate, further improves the working efficiency and reduces the enterprise operation cost.
Description
Technical field:
This utility model relates to the technical field of aid, is specifically related to rotary steel wire falling object fishing tool.
Background technology:
In water injection well in oil fields test process, logging steel wire is former due to long-time use, pulling force over loading, steel wire sand holes etc.
Because causing pit shaft steel wire junk, it it is a production difficult problem for very bad relatively common process.Falling in the wellbore is stayed after steel wire fracture
Thing will affect and enter under test instrunment and must salvage.The usual way of steel wire fishing junk is all first to use gravity drifting at present
Steel wire in well is pounded agglomerating by device, weighted lever etc., then salvages with the fishing head with barb.Due to steel wire during execute-in-place
Usually pounded into hard dead group, being stuck when above carrying by packer, so that salvaging unsuccessfully, water well operation have to be carried out, increase
Enterprise's production cost.
Utility model content:
In order to solve the problems referred to above, this utility model provides a kind of rotary steel wire falling object fishing tool, this salvaging work
Tool not only solves that steel wire during current steel wire fishing junk is difficult to be held, steel wire group is usually pounded into when carrying in hard dead group
The problem easily blocked by packer, has saved manpower simultaneously, improves the success rate of salvaging, further improves work effect
Rate, reduce the cost of enterprise's operation.
In order to achieve the above object, the following technological improvement of this utility model employing:
Rotary steel wire falling object fishing tool, mainly by strong magnetic adsorption plate, hard hook, soft hook, point lance and rotary shaft five part group
Become；Described coupler body mainly includes point lance, hard hook, soft hook three part；Point lance is installed on the top of coupler body, sets near the position of point lance
Putting and the hard hook that point lance is integral type structure, be mounted with strong magnetic adsorption plate salvaging on hard hook inclined-plane, fishing spear is outside is every magnetic
Material, suction piece is circular；Described soft hook is arranged on coupler body the latter half, the bottom of coupler body arrange top assist hard hook, and on
Portion assists hard hook and coupler body to be integral type structure；Described rotary shaft and coupler body are by being arranged on the rotary shaft of coupler body the latter half
The fixed installation of hole, location；Described rotation the tip of the axis is provided with screw thread form.
This utility model, through above-mentioned technological improvement, has reached following beneficial effect:
This fishing tool not only solve steel wire during current steel wire fishing junk be difficult to be held, steel wire group usually by
Pound into the problem easily blocked by packer when putting forward in hard dead group, saved manpower simultaneously, improve the success rate of salvaging, enter one
Improve work efficiency, reduce the cost of enterprise's operation of step.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of this utility model rotary steel wire falling object fishing tool.
Detailed description of the invention:
Below in conjunction with the accompanying drawings, this utility model is described further:
Rotary steel wire falling object fishing tool, mainly by strong magnetic adsorption plate 4, hard hook 3, soft hook 2, point lance 1 and rotary shaft 7 five
It is grouped into；Described coupler body mainly includes point lance 1, hard hook 3, soft hook 2 three part；Point lance 1 is installed on the top of coupler body, near point lance
The hard hook 3 that the position of 1 is arranged with point lance 1 is integral type structure, is mounted with strong magnetic adsorption plate 4, fishing spear salvaging on hard hook 3 inclined-plane
Outside is every magnetic material, and strong magnetic adsorption plate 4 is circular；Described soft hook 2 is arranged on coupler body the latter half, and the bottom of coupler body is arranged
Top assists hard hook 6, and the top hard hook of auxiliary 6 and coupler body are integral type structure；Described rotary shaft 7 and coupler body are by being arranged on
The hole 5, rotary shaft location of coupler body the latter half fixedly mounts；The end of described rotary shaft 7 is provided with screw thread.
Specific embodiment is as follows:
1, spinfunction.When this device and oscillator combination are gone into the well, rotate under the impact of High-Pressure Water, Ke Yi
Catch steel wire in the range of pipe wall internal diameters 360 °, solve and be close to tube inner wall because of the effect of steel wire natural resiliency power in the past,
Fishing head is difficult to get the opportunity a difficult problem for steel wire.
2, strong magnetic function.In order to make steel wire fracture head enter fishing device smoothly, it is mounted with on hard hook inclined-plane salvaging
Strong magnetic adsorption plate 4, fishing spear is outside is every magnetic material, and strong magnetic adsorption plate 4 is circular, a diameter of 10mm.Strong magnetic adsorption plate 4 is along with salvaging
Spear body rotates, and grabs steel wire at 65mm tube inner wall without dead angle suction.
3, soft or hard hook is supporting.The outside soft a diameter of 2.7mm of hook 2, a diameter of 25.5mm at internal hard hook 3, soft hook 2 is descending
Process is close to tube inner wall and is elapsed downwards by steel wire, makes steel wire produce bounce, simultaneously at the suction of strong magnetic and revolving force
Under effect, can make steel wire winding on soft or hard hook, when being lifted up soft or hard hook simultaneously stress, it is to avoid in the past pounded because of steel wire
Become the generation salvaging unsuccessful phenomenon that hard dead group and soft hook holding capacity cause not.
This fishing device scene application operating step:
1. arrive the scene of salvaging, this device is connected with agitator.
2. calculate fishing device depth of falling well according to the steel wire length that drops.
3. fishing device is put in pit shaft.
4. slowly drop position close to steel wire, determine whether to have caught on steel wire with lifting operation.
5. carry fishing tool on, until steel wire salvaging is gone out ground.
This fishing tool not only solve steel wire during current steel wire fishing junk be difficult to be held, steel wire group usually by
Pound into the problem easily blocked by packer when putting forward in hard dead group, saved manpower simultaneously, improve the success rate of salvaging, enter one
Improve work efficiency, reduce the cost of enterprise's operation of step.
In addition to the technical characteristic described in description above, it is the known technology of those skilled in the art.
