Description
Technical field
Opened an umbrella formula steel wire rope pusher the present invention relates to one kind, be applied particularly to Oil/gas Well steel wire rope operation, especially
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 one kind and opened an umbrella formula steel wire rope pusher.
To reach above-mentioned purpose, the present invention adopts the technical scheme that：
One kind opens an umbrella formula steel wire rope pusher, including top connection, upper connecting rod, baffle ring, mandrel, flow plug, contiguous block, peace
Fill ring, lower link, spacing ring, sliding sleeve；Top connection is installed in mandrel upper end, and mandrel lower end installation sliding sleeve, upper connecting rod one end is hinged to
The top connection other end is hinged to contiguous block, and lower link one end is hinged to the sliding sleeve other end and is hinged to contiguous block, mandrel centre position
Mounting ring is set, mounting ring and sliding sleeve is connected with extension spring, flow plug is set between upper connecting rod；It is characterized in that：
Mandrel centre position sets step, and mounting ring is arranged on mandrel stepped locations and uses threaded connection, outside mounting ring
Side installation locking nut；End cone button connects top connection in mandrel, and mandrel lower end installation sliding sleeve, mandrel lower end is close to step surface position
Spacing ring is installed, is screwed between spacing ring and mandrel；Extension spring is set between sliding sleeve and mounting ring, extension spring
One end is connected on the hook of sliding sleeve end, and the other end of extension spring is connected on the hook of mounting ring lower end；
Upper connecting rod one end is hinged on the outside of top connection, and the other end is hinged on contiguous block；Lower link one end is hinged to sliding sleeve
On, the other end is hinged on contiguous block；Plow-shape plate is set on the outside of contiguous block, and the plow-shape plate is circular arc-shaped metal plate and is welded to
Contiguous block longitudinal center position；
Flow plug is conical shell, and flow plug is arranged on upper connecting rod and sets pressure close to mandrel side, flow plug marginal position
Bar, it is connected with press strip and upper connecting rod；Mandrel upper end sets step and installs baffle ring, and flow plug center sets circular hole simultaneously
Mandrel upper end is enclosed on, top connection and baffle ring clamp the centre of flow plug.
The invention has the advantages that：1st, can be by velocity of medium in adjusting sleeve pipe, to adjust feeder
Drag force, it can preferably connect fish head；2nd, the present invention is advanced using fluid forces in sleeve pipe, can be used for horizontal well, big
Steel wire rope fishing in Wells casing drilling；3rd, mechanism of the present invention has reducing function, and casing deformation is adapted to
Property is strong.

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.
The centre position of mandrel 4 sets step, and mounting ring 9 is arranged on the stepped locations of mandrel 4 and using threaded connection, mounting ring
9 outside installation locking nuts 11；End cone button connects top connection 1 in mandrel 4, and the upper end of top connection 1 sets box to be used to connect top
Instrument；Sliding sleeve 15 is installed in the lower end of mandrel 4, and sliding sleeve 15 is enclosed on outside mandrel 4.Spacing ring is installed close to step surface position in the lower end of mandrel 4
14, it is screwed between spacing ring 14 and mandrel 4.Spacing ring 14 limits the distance that sliding sleeve 15 moves toward mounting ring 9, prevents
Connecting rod 2 and the transition of lower link 13 strut.The lower end of mounting ring 9 sets hook 10 and using threaded connection, and the upper end of sliding sleeve 15, which is set, to hang
Hook 10 simultaneously uses threaded connection, extension spring 12 is set between sliding sleeve 15 and mounting ring 9, one end of extension spring 12 is connected to cunning
Cover on the hook 10 of 15 ends, the other end of extension spring 12 is connected on the hook 10 of the lower end of mounting ring 9.
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 8；The one end of lower link 13 is hinged to
On sliding sleeve 15, the other end is hinged on contiguous block 8.The outside of contiguous block 8 sets plow-shape plate 7, and the plow-shape plate 7 is circular arc-shaped metal
Plate is simultaneously welded to the longitudinal center position of contiguous block 8.
Flow plug 6 is conical shell, and flow plug 6 is arranged on upper connecting rod 2 and installed close to the side of mandrel 4, the margin location of flow plug 6
Press strip 5 is put, press strip 5 and upper connecting rod 2 is connected with and compresses flow plug 6；The upper end of mandrel 4 sets step and installs baffle ring 3, hinders
Stream device 6 center sets circular hole and is enclosed on the upper end of mandrel 4, the centre of top connection 1 and the clamping flow plug 6 of baffle ring 3.
The present invention principle be：
When going into the well, under the pulling force effect of extension spring 12, sliding sleeve 15 is relative to the upward sliding of mandrel 4, and upper connecting rod 2 is with
Connecting rod 13 struts and drives flow plug 6 to deploy, and the media flow in sleeve pipe promotes the present apparatus to move downward.It is lifted up steel wire rope
When, lower tool, fish etc. have weight, and upper lower pulling force causes upper connecting rod 2 and lower link 13 to collapse automatically, facilitates instrument
Recovery.
