Description
Technical field
The present invention relates to a kind of underground fishing tool, and in particular to a kind of deep-well, which breaks, falls drilling tool fishing device.
Background technology
It is also increasing for petroleum resources usage amount with continuing to develop for China's economy.But in the reality of oil
In exploitation for oil field well junk salvage attention degree but relative deficiency, this will make for the exploitation work in oil field
Into larger harm.So-called oil field well junk, is primarily referred to as dropping down on oil exploitation well head or tubing string, well logging apparatus
In the metal in well or other various tangible materials.Particularly may be divided under junk under tubing, shaft-like lower junk, rope form junk and
Tiny lower junk etc..Lower junk is quite big for the exploitation reality of work harm in oil field, easily blocks oil reservoir, serious meeting is made
Into scrapping for oil well sidetracking.
So prior art occurs in that the special instrument to salvage trouble of lost tool in hole and processing down-hole accident.Conventional salvaging work
With die nipple, female coupling tap, fishing socket, fishing spear, junk basket, magnet fisher, junk mill, safety joint etc..But these instruments are usual
It is made up of a fishing rod and a fishing head.But well internal channel is not always straight line, has many serpentine channels
In the presence of, fishing rod is often designed as bent stick in the prior art, salvaged with this, this kind of mode need every time according to serpentine channel
Flexibility will change bent stick flexibility, very bother, which increase salvage difficulty.
The content of the invention
Break it is an object of the invention to provide a kind of deep-well and fall drilling tool fishing device, solving existing fishing tool can not fit
Deep-well for differently curved situation so that salvaging step becomes complicated, the problem of increasing salvaging difficulty.
The present invention is achieved through the following technical solutions：
A kind of deep-well, which breaks, falls drilling tool fishing device, including fishing rod, and the fishing rod includes at least two connecting rods, two
A cylindricality connector is provided between individual connecting rod, the two ends of the cylindricality connector have a U-shaped card slot, described
The end of connecting rod is located in U-shaped card slot and is hinged with cylindricality connector；A rotation is additionally provided with the cylindricality connector
Axle, the rotary shaft is located between two U-shaped card slots, and the axis of rotary shaft is overlapped with the center line of connecting rod.Further,
The present invention devises a kind of new fishing rod, and fishing rod is divided into at least two connecting rods, is connected with each other in two connecting rods
End set a cylindricality connector, the end of two connecting rods is stuck in the U-shaped card slot of cylindricality connector, then using one
Individual rotating shaft sequentially passes through U-shaped card slot and connecting rod, makes an articulated structure, so can easily change two connections
The flexibility of bar.When multiple connecting rods are linked together by cylindricality connector, you can according to the flexibility of well internal channel, from
By change fishing rod crooked position.In addition, also setting up a rotary shaft in the middle part of cylindricality connector, so can freely it change
Become the bending direction of connecting rod, it is convenient and practical.
It is preferred that, a fishing head is additionally provided with one end of fishing rod.
It is preferred that, the fishing head includes a cylinder barred body, and several hangnails are provided with cylinder barred body.Further
, this kind of mode is applied to salvage the junks such as pump block, shorter tube, the rubber of Intermediate Gray eye.
It is preferred that, the fishing head includes a circular magnetic disc, and the circular magnetic disc is provided with one away from the side of fishing rod
Individual circular groove.Further, this kind of mode is applied to salvage some metal findings, using the magnetic of circular magnetic disc by metal
Finding absorption is got up.Circular magnetic disc is designed as groove structure, can be in the centre of circular magnetic disc positioned at the magnetic field of recess sidewall
Strengthen so that the absorption affinity of circular magnetic disc is strengthened.
It is preferred that, the fishing head includes cylinder, and the axis of the internal diameter of the cylinder along fishing rod is towards away from salvaging
The dimension linear increase of bar.The fishing head of drum type brake is used to salvage the shaft for being broken and standing upright in well, the internal diameter court of cylinder
Dimension linear increase away from fishing rod is applicable to match the shank diameter of different-diameter.Fracture bar is stuck in cylinder during salvaging
It is interior, vertical pull-up.
The present invention compared with prior art, has the following advantages and advantages：
A kind of deep-well of the present invention, which breaks, falls drilling tool fishing device, can convenient regulation fishing rod flexibility, to adapt to different wells
The bending situation in road, solves the problem of being needed before salvaging according to the bending situation in well newly to prepare a fishing rod, drop
Low salvaging difficulty so that it is more convenient to salvage, economical and practical.
