Description
Technical field
The present invention relates to a kind of drilling tool salvaging steel wire rope pusher, Oil/gas Well steel wire rope operation is applied particularly to, especially
It is drilling tool fishing in casing drilling.
Background technology
Casing drilling system refers to a kind of well system as drill string with ordinary casing, and sleeve pipe had both transmitted mechanical energy and (turned round
Square), liquid energy is transmitted again to drill bit.It can accomplish the setting of casing when boring, and save a large amount of shaft building costs.Removed with reduction
Bore number, shorten the trip time, save expense, reduce down-hole accident the advantages that.
Recoverable casing drilling instrument is most widely used at present, and the technique is salvaged casing part using steel wire rope and bored
Tool.Steel wire rope rises and gone into the well with the advantages of efficient, quick, is widely used applied to operations such as well workover, salvaging, well loggings.Conventional steel
During cord is salvaged, rely primarily in steel wire rope fishing head deadweight tripping in sleeve pipe, for high angle hole and horizontal well steel wire rope
Tripping in is difficult, therefore the technique application is restricted.
On the other hand, by fishing head conduct oneself with dignity 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 which smoothly connection fishing head and fish head, causing to pull out of hole fails.For these reasons, mesh
Preceding recoverable casing drilling, although being mainly used in Vertical Well, down-hole equipment probability of recycling success is also only 70% or so.
Therefore, more structurally sound steel wire rope fishing tool is developed, is of great value and bright prospects.
The content of the invention
The purpose of the present invention：In order to overcome in existing drilling tool recoverable casing drilling technique, drilling tool probability of recycling success is low
The shortcomings that, spy provides a kind of drilling tool salvaging and uses steel wire rope pusher.
To reach above-mentioned purpose, the present invention adopts the technical scheme that：
A kind of drilling tool, which is salvaged, uses steel wire rope pusher, including top connection, upper connecting rod, mandrel, contiguous block, choke apparatus,
Mounting ring, lower link, hook, sliding sleeve, lower contact；Mandrel upper end is installed by top connection, mandrel lower end installation sliding sleeve, upper connecting rod one end
It is hinged to the top connection other end and is 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, and choke apparatus is set between mounting ring and contiguous block, and mounting ring and sliding sleeve are connected with extension spring, its
It is characterised by：
Mandrel centre position sets step, and mounting ring is arranged on mandrel stepped locations and using threaded connection；Mandrel upper end
Cone button connection top connection, top connection upper end sets box；Sliding sleeve is installed in mandrel lower end, and end cone button connects lower contact under sliding sleeve, under
Joint lower end sets pin thread, and sliding sleeve sets radial direction through hole close to lower contact position；
Contiguous block both sides set hook, and choke apparatus is that either cloth or nylon facing material, choke apparatus are whole for rubber sheet
Body is irregular annular, is installed on the inside of choke apparatus by connection ring on the hook of mounting ring surrounding, outside choke apparatus
Side is installed to by connection ring on the hook on contiguous block both sides；
Sliding sleeve and the adjacent side of mounting ring set spring carrier arm and using threaded connections, set and draw between sliding sleeve and mounting ring
Spring is stretched, one end of extension spring is connected on the hook of sliding sleeve end, and the other end of extension spring is connected to mounting ring lower end
Hook on.
The invention has the advantages that：1st, mechanism of the present invention has reducing function, to casing deformation adaptability
By force；2nd, the present invention is advanced using fluid forces in sleeve pipe, and the steel wire rope that can be used in horizontal well, high angle hole casing drilling is beaten
Drag for operation；3rd, fish to adjust the drag force of feeder, can preferably be connected by velocity of medium in adjusting sleeve pipe
Head.

Embodiment
The present invention is not limited by following embodiments, can be determined with technique according to the invention scheme and actual conditions
Specific embodiment.Make following describe with reference to Fig. 1~3 pair present invention.The position relationship of upper and lower, left and right etc. is foundation
The layout direction of Figure of description 1 determines.
The centre position of mandrel 3 sets step, and mounting ring 6 is arranged on the stepped locations of mandrel 3 and using threaded connection；Mandrel 3
Upper end cone button connects top connection 1, and the upper end of top connection 1 sets box to be used to connect upper tool；Sliding sleeve 10 is installed in the lower end of mandrel 3,
Sliding sleeve 10 is enclosed on outside mandrel 3, and 10 times end cone button connection lower contacts 11 of sliding sleeve, the lower end of lower contact 11 sets pin thread and under connection
Portion's instrument.Sliding sleeve 10 sets radial direction through hole close to the position of lower contact 11, sliding sleeve 10 when preventing 10 relative motion of mandrel 3 and sliding sleeve
Inside build the pressure.
The one end of upper connecting rod 2 is hinged to the outside of top connection 1, and the other end is hinged on contiguous block 4；The one end of lower link 7 is hinged to
On sliding sleeve 10, the other end is hinged on contiguous block 4, and the both sides of contiguous block 4 set hook 9 and using threaded connection.
Choke apparatus 5 is rubber sheet either cloth or nylon facing material, the generally irregular annulus of choke apparatus 5
Shape, the inner side of choke apparatus 5 are installed to by connection ring 12 on the hook 9 of the surrounding of mounting ring 6, and the outside of choke apparatus 5 passes through connection
Ring 12 is installed on the hook 9 on the both sides of contiguous block 4.
Sliding sleeve 10 and 6 adjacent side of mounting ring set spring carrier arm 9 simultaneously using threaded connection, sliding sleeve 10 and mounting ring 6 it
Between extension spring 8 is set, one end of extension spring 8 is connected on the hook 9 of the end of sliding sleeve 10, and the other end of extension spring 8 connects
It is connected on the hook 9 of the lower end of mounting ring 6.
