Description
Technical field
The utility model relates to a kind of tools for downhole of oil field, and concrete is a kind of oilfield down-hole salvager.
Background technology
At present, in the process of oily underground work, for the large tubulose trouble of lost tool in hole of caliber, the general slips-type tool extractor that adopts, but for the less elongated junk of caliber, as the junks such as cable, wire rope, steel wire for logging are often spiral Texturized, general slips-type tool extractor in well, tend to lose efficacy, be difficult to smooth salvaging; And for the junk such as agglomerating cable, wire rope, steel wire for logging in well, the outer hook in general outer hook type fishing device is inserted not enter, and cannot salvage.The existing weak point of prior art that Here it is.
Utility model content
Technical problem to be solved in the utility model, is exactly for the existing deficiency of prior art, and a kind of oilfield down-hole salvager is provided, and can conveniently salvage in elongated junk that caliber is less and well agglomerating elongated junk.
This programme is achieved by the following technical measures: a kind of oilfield down-hole salvager, it comprises top connection, interior fishing rod and outer fishing rod, described interior fishing rod, outer fishing rod is connected with top connection lower end, on described outer fishing rod, be symmetrically arranged with two fixed hooks that Open Side Down, on described interior fishing rod outer wall, be provided with Removable hook group, described Removable hook group is positioned at the below of fixed hook, described Removable hook group comprises two identical Removable hooks, the opening direction of described Removable hook is contrary with fixed hook, described Removable hook lower end is hinged by hinge and interior fishing rod, middle part is connected with interior fishing rod with stay cord by back-moving spring, described Removable hook upper end is provided with teeth, middle part is provided with collection groove, the pin joint of described two Removable hooks and interior fishing rod is symmetrical about interior fishing rod axis, described two Removable hook upper ends lay respectively at the both sides of two pin joint lines, described back-moving spring and stay cord are positioned at the top at Removable hook middle part.
On above-mentioned interior fishing rod outer wall, be arranged at intervals with a plurality of Removable hook groups.
The lower end of above-mentioned interior fishing rod is pyramidal structure.
Teeth on above-mentioned Removable hook are uniformly distributed.
The beneficial effects of the utility model can be learnt from above-mentioned technical scheme: the oilfield down-hole salvager that the utility model provides is scraped collection by fixed hook downwards by elongated junk, Removable hook is below collected elongated junk, has improved the success rate of the salvaging of the elongated junks such as cable, wire rope, steel wire for logging; After the elongated junks such as cable, wire rope, steel wire for logging are agglomerating, the Removable hook interior fishing rod of can retracting that is hampered, like this, fishing rod is easy to insert in agglomerating elongated junk, on while carrying, Removable hook opens by back-moving spring, teeth tangle agglomerating junk, stay cord can be strained Removable hook, avoid agglomerating junk to come off from teeth, improve the application life of back-moving spring, improved the success rate of agglomerating fishing junk.Oilfield down-hole salvager described in the utility model is simple in structure, and applicability is strong.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment.
1-top connection in figure, the outer fishing rod of 2-, 3-fixed hook, fishing rod in 4-, 5-Removable hook, 5.1-teeth, 5.2-collection groove, 6-back-moving spring, 7-hinge, 8-stay cord, 9-Removable hook group.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in the figure: a kind of oilfield down-hole salvager, it comprises top connection 1, interior fishing rod 4 and outer fishing rod 2, described interior fishing rod 4, outer fishing rod 2 is connected with top connection 1 lower end, on described outer fishing rod 2, be symmetrically arranged with two fixed hooks that Open Side Down 3, on described interior fishing rod 4 outer walls, be provided with Removable hook group 9, described Removable hook group 9 is positioned at the below of fixed hook 3, described Removable hook group 9 comprises two identical Removable hooks 5, the opening direction of described Removable hook 5 is contrary with fixed hook 3, described Removable hook 5 lower ends are hinged by hinge 7 and interior fishing rod 4, middle part is connected with interior fishing rod 4 with stay cord 8 by back-moving spring 6, described Removable hook 5 upper ends are provided with teeth 5.1, middle part is provided with collection groove 5.2, described two Removable hooks 5 are symmetrical about interior fishing rod 4 axis with the pin joint of interior fishing rod 4, described two Removable hook 5 upper ends lay respectively at the both sides of two pin joint lines, described back-moving spring 6 and stay cord 8 are positioned at the top at Removable hook 5 middle parts.When salvaging agglomerating junk, in Removable hook group 9, the teeth 5.1 of two Removable hook 5 upper ends tangle agglomerating junk simultaneously, and evenly the application of force, effectively prevents coming off of agglomerating junk, improves the success rate of agglomerating fishing junk, and described stay cord 8 is non-resilient rope.
On above-mentioned interior fishing rod 4 outer walls, be arranged at intervals with a plurality of Removable hook groups 9.In the present embodiment, on interior fishing rod 4 outer walls, be provided with two Removable hook groups 9.
The lower end of above-mentioned interior fishing rod 4 is pyramidal structure.
Teeth 5.1 on above-mentioned Removable hook 5 are uniformly distributed.
