Description
Technical field
The present invention relates to a kind of steel wire rope feeder with leather cup, it is applied particularly to Oil/gas Well steel wire rope operation, especially sleeve pipe
Drilling fishing.
Background technology
Casing drilling system refers to a kind of well system with ordinary casing as drill string, and sleeve pipe had both transmitted mechanical energy (moment of torsion), and
Transmission liquid energy is to drill bit.It can accomplish the setting of casing in brill, saves a large amount of shaft building costs.There is minimizing make a trip number of times,
Shorten the trip time, save the advantages of expense, minimizing down-hole accident.
Recoverable casing drilling instrument is most widely used at present, and this technique adopts steel wire rope to salvage sleeve pipe lower drilling tool.Steel wire
Having restricted goes into the well has efficient, quick advantage, is widely used and is applied to the operations such as well workover, salvaging, well logging.Conventional steel wires rope is beaten
During dragging for, rely primarily on and enter in sleeve pipe under the deadweight of steel wire rope fishing head, enter difficulty under high angle hole and horizontal well steel wire rope,
Therefore this technique application is restricted.
On the other hand, the mode relying on fishing head deadweight is connected with lower tool fish joint, often because casing deformation, tube wall
The problems such as contact force is excessive, it is impossible to smoothly connect fishing head and fish head, causes to pull out of hole unsuccessfully.For these reasons, at present may be used
Recovery type casing drilling, although being mainly used in Vertical Well, down-hole equipment probability of recycling success is also only 70% about.
Therefore, develop more structurally sound steel wire rope fishing tool, be of great value and bright prospects.
Content of the invention
The purpose of the present invention：In order to overcome in existing drilling tool recoverable casing drilling technique, the low shortcoming of drilling tool probability of recycling success,
A kind of steel wire rope feeder with leather cup of special offer.
For reaching above-mentioned purpose, the present invention adopts the technical scheme that：
A kind of steel wire rope feeder with leather cup, including lower contact, lower baffle ring, leather cup, strut, heart axle, spacing ring, cunning
Set, compression spring, spring baffle ring；Sliding sleeve is installed in heart axle upper end, arranges compression spring between heart axle and sliding sleeve, and heart axle lower end is even
Connect lower contact, leather cup clamps centrally through the lower baffle ring of lower contact and heart axle lower end, and it is hinged that strut one end is hinged to the sliding sleeve other end
To on the journal stirrup at leather cup edge it is characterised in that：
Sliding sleeve is contained in outside heart axle, and sliding sleeve upper end is threaded joint, and sliding sleeve arranges radial direction through hole, sliding sleeve near nipple position
Centre position arranges setting step in radial direction through hole, sliding sleeve, and heart axle arranges step near sliding sleeve interior step position；Heart axle upper end
It is threaded and installs spring baffle ring, compression spring withstands on step in spring baffle ring and sliding sleeve；
Heart axle lower end arranges step, and described stepped locations install lower baffle ring, and heart axle lower end is connected with lower contact cone button, under lower contact
End is threaded joint；Leather cup material is rubber, and leather cup center arranges circular hole, and heart axle lower end passes through circular hole described in leather cup,
Lower baffle ring and lower contact clamp leather cup center hole and fix；Strut one end is hinged on the journal stirrup of leather cup, and the other end is hinged to cunning
Put；
Leather cup inside edge position arranges journal stirrup, and described ear material is rubber and is fixed with one with leather cup；Leather cup is two neighboring
Journal stirrup is arranged in parallel, and journal stirrup both sides are respectively provided with installation gasket ring, and strut lower end is arranged on two neighboring in ear of leather cup, uses bolt
Connect journal stirrup and strut, described bolt end pad and nut fastening.
The invention has the advantages that：1st, the present invention adopts fluid forces in sleeve pipe to advance, and can be used for horizontal well, oblique greatly
Steel wire rope fishing in degree casing drilling well；2nd, mechanism of the present invention has reducing function, to casing deformation strong adaptability；
When the 3rd, going into the well, leather cup blocks medium in sleeve pipe, and medium promotes this device descending inside the Pass, and motive force is big, and lower connector can be more
Good connection fish head.

Specific embodiment
The present invention is not limited by following embodiments, can be determined specifically with technology according to the present invention scheme and practical situation
Embodiment.Make following description with reference to Fig. 1～3 pair present invention.The position relationship of upper and lower, left and right etc. is according to explanation
The layout direction of book accompanying drawing 1 is determining.
Sliding sleeve 8 is contained in outside heart axle 6, and sliding sleeve 8 upper end is threaded joint for connecting steel wire ropes adapter or upper tool,
Sliding sleeve 8 arranges radial direction through hole near nipple position, and sliding sleeve 8 centre position arranges radial direction through hole, setting step in sliding sleeve 8,
Compression spring 9 is installed to the annular space between sliding sleeve 8 and heart axle 6.Heart axle 6 is near sliding sleeve 8 interior step position setting table
Rank, when above carrying instrument, step described in heart axle 6 and sliding sleeve 8 interior step combine and transmit axial tension.Heart axle 6 upper end sets
Put screw thread and spring baffle ring 10 is installed, the outer installation locking nut 11 of spring baffle ring 10.Compression spring 9 withstands on spring baffle ring 10 He
On step in sliding sleeve 8.Sliding sleeve 8 upper end arranges radial direction through hole, and sliding sleeve 8 centre position arranges radial direction through hole, such sliding sleeve 8 He
When heart axle 6 slides relatively, the medium in the cavity of the medium in space residing for compression spring 9 and spring baffle ring 10 upper end
Can free in and out, prevent from building the pressure.
Heart axle 6 lower end arranges step, and described stepped locations install lower baffle ring 2, and heart axle 6 lower end is connected with lower contact 1 cone button,
Lower contact 1 lower end is threaded joint and is used for connecting lower tool.Heart axle 6 arranges spacing ring 7 in sliding sleeve 8 installation site lower end,
It is screwed between described spacing ring 7 and heart axle 6, spacing ring 7 limits the effect in compression spring 9 of sliding sleeve 8 and heart axle 6
Lower sliding distance relatively, prevents leather cup 3 from strutting transition.
Leather cup 3 material is rubber, and leather cup 3 center arranges circular hole, and heart axle 6 lower end passes through circular hole, lower block described in leather cup 3
Ring 2 and lower contact 1 clamp leather cup 3 center hole and fix.Strut 5 one end is hinged on the journal stirrup 4 of leather cup 3, the other end
It is hinged on sliding sleeve 8.
Leather cup 3 inside edge position arranges journal stirrup 4, and described journal stirrup 4 material is rubber and is fixed with one with leather cup 3.Leather cup 3
Two neighboring journal stirrup 4 is arranged in parallel, and journal stirrup 4 both sides are respectively provided with installation gasket ring 12, and it is adjacent that strut 5 lower end is arranged on leather cup 3
In two journal stirrups 4, connect journal stirrup 4 and strut 5, described bolt 13 end pad and nut fastening with bolt 13.
The principle of the present invention is：
When going into the well, under compression spring 9 thrust, sliding sleeve 8 promotes leather cup with respect to heart axle 6 slide downward, strut 5
3 launch closure sleeve pipe, and in sleeve pipe, flow of fluid can drive this device descending.When being lifted up steel wire rope, lower tool,
Fish etc. has weight, and upper lower pulling force makes leather cup 3 automatically draw in, facilitates instrument to reclaim；And, lower tool weight is by sliding
In set 8, the step of step and this position of heart axle 6 bears, and prevents compression spring 9 supercompression.
