Technical field
The present invention relates to a kind of drilling tool salvaging steel wire rope pusher, be applied particularly to Oil/gas Well steel wire rope operation, especially
It is drilling tool fishing in casing drilling.
Background technology
Casing drilling system refers to a kind of well system using ordinary casing as drill string, and sleeve pipe had both transmitted mechanical energy and (turned round
Square), transmission liquid energy is to drill bit again.It can accomplish brill limit, limit setting of casing, saves a large amount of shaft building cost.There is minimizing remove
Bore number of times, shorten the trip time, save expense, reduce the advantages such as down-hole accident.
Recoverable casing drilling instrument is most widely used at present, and this technique uses steel wire rope to salvage casing part and bores
Tool.Steel wire rope rises to go into the well has advantage efficient, quick, be widely used be applied to well workover, salvage, the operation such as well logging.Conventional steel
During cord is salvaged, rely primarily on and enter in sleeve pipe, for high angle hole and horizontal well steel wire rope under the deadweight of steel wire rope fishing head
Under enter difficulty, therefore this technique application be restricted.
On the other hand, rely on fishing head deadweight mode be connected with lower tool fish joint, often because of casing deformation,
The problems such as tube wall contact force is excessive, it is impossible to connect fishing head and fish head smoothly, cause and pull out of hole unsuccessfully.For these reasons, mesh
Front recoverable casing drilling, although being mainly used in Vertical Well, but down-hole equipment is recycled into power and is also only about 70%.
Therefore, develop more structurally sound steel wire rope fishing tool, be of great value and bright prospects.
Summary of the invention
The purpose of the present invention: in order to overcome in existing drilling tool recoverable casing drilling technique, it is low that drilling tool is recycled into power
Shortcoming, special provide a kind of drilling tool to salvage to use steel wire rope pusher.
For reaching above-mentioned purpose, the present invention adopts the technical scheme that:
A kind of drilling tool is salvaged and is used steel wire rope pusher, including top connection, upper connecting rod, mandrel, contiguous block, choke apparatus,
Mounting ring, lower link, hook, sliding sleeve, lower contact；Joint is installed in mandrel upper end, and sliding sleeve, upper connecting rod one end are installed in mandrel lower end
Being hinged to the top connection other end and be hinged to contiguous block, lower link one end is hinged to the sliding sleeve other end and is hinged to contiguous block, in mandrel
Meta installs mounting ring, arranges choke apparatus between mounting ring and contiguous block, connects mounting ring and sliding sleeve with stretching spring, its
It is characterised by:
Mandrel centre position arranges step, and mounting ring is arranged on mandrel stepped locations and uses threaded；Mandrel upper end
Cone button connects top connection, and top connection upper end arranges box；Sliding sleeve is installed in mandrel lower end, and under sliding sleeve, end cone button connects lower contact, under
Joint lower end arranges pin thread, and sliding sleeve arranges radial direction through hole near lower contact position；
Contiguous block both sides arrange hook, and choke apparatus is rubber sheet or cloth or nylon facing material, and choke apparatus is whole
Body is irregular annular, is installed on the hook of mounting ring surrounding, outside choke apparatus by connection ring inside choke apparatus
Side is installed on the hook on contiguous block both sides by connecting ring；
Sliding sleeve and the adjacent side of mounting ring arrange spring carrier arm and use threaded, arrange and draw between sliding sleeve and mounting ring
Stretching spring, one end of stretching spring is connected on the hook of sliding sleeve end, and the other end of stretching spring is connected to mounting ring lower end
Hook on.
The invention have the advantages that: 1, mechanism of the present invention has reducing function, to casing deformation adaptability
By force；2, in the present invention uses sleeve pipe, fluid forces advances, and the steel wire rope that may be used in horizontal well, high angle hole casing drilling is beaten
Drag for operation；3, the drag force of feeder can be regulated, it is possible to preferably connect fish by velocity of medium in adjusting sleeve pipe
Head.

Detailed description of the invention
The present invention is not limited by following embodiment, can determine according to technical scheme and practical situation
Specific embodiment.Following description is made below in conjunction with Fig. 1～3 couples of present invention.The position relationship of upper and lower, left and right etc. is based on
The layout direction of Figure of description 1 determines.
Mandrel 3 centre position arranges step, and mounting ring 6 is arranged on mandrel 3 stepped locations and uses threaded；Mandrel 3
Upper end cone button connects top connection 1, and top connection 1 upper end arranges box for connecting upper tool；Sliding sleeve 10 is installed in mandrel 3 lower end,
Sliding sleeve 10 is enclosed within outside mandrel 3, and 10 times end cone buttons of sliding sleeve connect lower contact 11, and lower contact 11 lower end arranges pin thread and under connecting
Portion's instrument.Sliding sleeve 10 arranges radial direction through hole near lower contact 11 position, sliding sleeve 10 when preventing mandrel 3 and sliding sleeve 10 relative motion
Inside build the pressure.
Upper connecting rod 2 one end is hinged to outside top connection 1, and the other end is hinged on contiguous block 4；Lower link 7 one end is hinged to
On sliding sleeve 10, the other end is hinged on contiguous block 4, and contiguous block 4 both sides arrange hook 9 and use threaded.
Choke apparatus 5 is rubber sheet or cloth or nylon facing material, the most irregular annulus of choke apparatus 5
Shape, is installed on the hook 9 of mounting ring 6 surrounding by connection ring 12 inside choke apparatus 5, by connecting outside choke apparatus 5
Ring 12 is installed on the hook 9 on contiguous block 4 both sides.
Sliding sleeve 10 and the adjacent side of mounting ring 6 arrange spring carrier arm 9 and use threaded, sliding sleeve 10 and mounting ring 6 it
Between stretching spring 8 is set, one end of stretching spring 8 is connected on the hook 9 of sliding sleeve 10 end, and the other end of stretching spring 8 is even
Receive on the hook 9 of mounting ring 6 lower end.
The principle of the present invention is:
When going into the well, under stretching spring 8 pulling force effect, sliding sleeve 10 is relative to mandrel 3 upward sliding, and contiguous block 4 is upper
Strutting and drive choke apparatus 5 to launch under connecting rod 2 and lower link 7 effect, the media flow in sleeve pipe promotes this device to transport downwards
Dynamic.The when of being lifted up steel wire rope, lower tool, fish etc. have weight, and upper lower pulling force makes connecting rod 2 and lower link 7
Automatically draw in, facilitate instrument to reclaim.
