Description
Technical field
The present invention relates to a kind of steel wire rope feeder, is applied particularly to Oil/gas Well steel wire rope operation, especially Sleeve drill
Drilling tool fishing in well.
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 steel wire rope feeder.
To reach above-mentioned purpose, the present invention adopts the technical scheme that：
A kind of steel wire rope feeder, including sliding sleeve, spring baffle ring, compression spring, mandrel, upper strut, lower supporting rod, umbrella shape
Set, lower contact, mandrel upper end installation sliding sleeve, the connection lower contact of mandrel lower end, upper strut and lower supporting rod are hinged, and upper strut is another
One end is hinged on sliding sleeve, and the lower supporting rod other end is hinged to lower contact, and umbrella sleeve is set between lower supporting rod, it is characterised in that：
For sliding sleeve outside mandrel, sliding sleeve upper end is threaded joint, and sliding sleeve sets radial direction through hole close to nipple position,
Sliding sleeve centre position sets radial direction through hole, and step is set in sliding sleeve；Mandrel upper end is threaded and installs spring baffle ring, spring catch
The outer installation locking nut of ring, compression spring are withstood in spring baffle ring and sliding sleeve on step；
Mandrel lower end is threadedly coupled with lower contact, and lower contact lower end is threaded joint；Upper strut and lower supporting rod are mutually cut with scissors
Connecing, strut and lower supporting rod are uniformly distributed in mandrel circumferencial direction at least 4 groups, and the upper strut other end is hinged to sliding sleeve lower end, under
The strut other end is hinged in lower contact；
Umbrella sleeve is conical shell, and umbrella shape cover material is that either cloth or nylon facing material, umbrella shape are set on down rubber
Strut sets press strip close to mandrel side on the inside of umbrella sleeve, the press strip is arranged in parallel with lower supporting rod, be connected with press strip and
Lower supporting rod simultaneously clamps umbrella sleeve.
The invention has the advantages that：1st, the present invention is advanced using fluid forces in sleeve pipe, can be used for horizontal well,
Steel wire rope fishing in high angle hole casing drilling；2nd, mechanism of the present invention has reducing function, and casing deformation is fitted
Ying Xingqiang；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 to the present invention with reference to Fig. 1, Fig. 2.The position relationship of upper and lower, left and right etc. be according to
Determined according to the layout direction of Figure of description 1.
Outside mandrel 5, the upper end of sliding sleeve 1 is threaded joint and is used for connecting steel wire ropes connector or top work sliding sleeve 1
Tool, sliding sleeve 1 set radial direction through hole close to nipple position, and the centre position of sliding sleeve 1 sets radial direction through hole, setting table in sliding sleeve 1
Rank, compression spring 4 are installed to the annular space between sliding sleeve 1 and mandrel 5.The upper end of mandrel 5 is threaded and installs spring baffle ring
3, the outer installation locking nut 2 of spring baffle ring 3.Compression spring 4 is withstood in spring baffle ring 3 and sliding sleeve 1 on step.The upper end of sliding sleeve 1 is set
Radial direction through hole is put, the centre position of sliding sleeve 1 sets radial direction through hole, when such sliding sleeve 1 and mandrel 5 are slided relatively, the institute of compression spring 4
Medium in the space at place and the medium in the cavity of the upper end of spring baffle ring 3 can free in and out, and prevent from building the pressure.
The lower end of mandrel 5 is threadedly coupled with lower contact 10, and the lower end of lower contact 10 is threaded joint and for connecting bottom work
Tool.Upper strut 6 and lower supporting rod 7 are hinged, and strut 6 and lower supporting rod 7 are uniformly distributed in mandrel circumferencial direction on 12 groups, upper strut
6 other ends are hinged to the lower end of sliding sleeve 1, and the other end of lower supporting rod 7 is hinged in lower contact 10.
Umbrella sleeve 9 is conical shell, and the material of umbrella sleeve 9 is rubber, and umbrella sleeve 9 is arranged on lower supporting rod 7 close to mandrel 5 one
Side, the inner side of umbrella sleeve 9 set press strip 8, and press strip 8 is arranged in parallel with lower supporting rod 7, is connected with press strip 8 and lower supporting rod 7 and clamps
Umbrella sleeve 9.
More optimize, device of the present invention can be with multiple uses that are together in series, between neighboring devices in indirectly
First 11 connection.So multiple support rod mechanisms can automatic centering, facilitate bottom to salvage first-class tool work.
The present invention principle be：
When going into the well, under the thrust of compression spring 4, sliding sleeve 1 is relative to the slide downward of mandrel 5, upper strut 6 and lower support
Bar 7 struts and withstands on internal surface of sleeve pipe, flow of fluid in sleeve pipe, produces throttling in the position of umbrella sleeve 9 that umbrella is opened, medium promotes
Mechanism of the present invention moves downward.When being lifted up steel wire rope, lower tool, fish etc. have weight, upper lower pulling force
So that upper strut 6 and lower supporting rod 7 collapse automatically, instrument is facilitated to reclaim.
