Description
Technical field
The invention mainly relates to a kind of frock for assisting tubing string tripping in, more specifically, is related under a kind of tubing string rotation
Enter instrument.
Background technology
As high angle hole, extended reach well and horizontal well technology are with more and more extensive, during well is drilled, well
The problems such as frictional resistance, tubing string deadweight and cutting bed are accumulated generally existing, cause tubing string be hampered and can not normal tripping in phenomenon it is frequent
Occur.In oil-gas mining, the frictional resistance that makes a trip is huge, send the problems such as not in place under brill difficulty, drill string also result in more and more
Concern.
At present, when occurring the complex situations such as viscous card in setting of casing, tail pipe operation process, outlet pipe has been generally required and has ganged up
Well, this method have increased considerably the activity duration, so that operation timeliness reduces, operating cost rise.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided one kind, which can reduce, fashionable under tubing string to be hampered
Risk, reduce time-consuming caused by tubing string tripping in is hampered, to ensure to be drilled, tubing string in well operations can smoothly tripping in be in place
Tubing string rotates tripping in instrument.
The purpose of the present invention is achieved through the following technical solutions.
The tubing string rotation tripping in instrument of the present invention, including upper and lower ends set female top connection, the top connection
Lower end is connected with connector, and the connector lower end outside is connected with spring strut, and inner side is connected with lower end outside band axial keyway
Splined shaft；Spring, thrust ball bearing and inner sleeve are from top to bottom disposed between the splined shaft and spring strut, it is described interior
Set lower end outside is connected with overcoat, and the overcoat lower end inside is connected with spline body, and the spline body lower end inside is connected with band
The piston cylinder of radial direction through hole, the piston cylinder inner side are fixedly installed lower spindle by shear pin, set on the outside of the lower spindle
The axial direction commutation track of integrative-structure is equipped with, the guide finger for fixed guide seat is provided with the track that commutates.
The lower spindle lower end outside is connected with lower contact, and the nut pad with through hole is provided with the outside of the lower contact；Institute
State and the upper spindle positioned at splined shaft, connector and inside top connection is connected with the inside of lower spindle upper end, the upper spindle and above connect
Self-aligning thrust roller bearing, bearing block and cylindrical roller thrust bearing, the bearing block are from top to bottom disposed between head
It is fixedly connected with upper spindle.
The top connection side wall is provided with two radial direction through hole, is respectively arranged with oil sac in through hole and oil blocks up.
The upper surface of the bearing block is provided with axial notch, and little spring is provided with groove.
The spring strut is circumferentially evenly arranged with radial direction through hole.
Outer sleaker is provided between the piston cylinder lower end and lower contact.
The lower spindle lower end edge even circumferential is provided with radial direction through hole.
Compared with prior art, beneficial effect caused by technical scheme is：
(1) in the present invention, splined shaft is in released state with spline body, by top connection, connector, splined shaft, spring bucket
It is fixedly secured to one another the bottom that the upper end of composition is formed with by remaining part to separate each other, upper and lower end is due to circle
The presence of post roller bearing and thrust ball bearing can separate rotation, i.e., upper end is still freely rotatable when bottom is fixed.Solution
Determined rotation top tubing string when run into the problem of frictional resistance is big, it is not necessary in tubing string moment of torsion applied below, so that it may so that upper tube post
Rotation, the frictional resistance for rotating and being run into during the tubing string of top is reduced, reduces tubing string because the problems such as frictional resistance produces simultaneously also by rotation
Raw weight loss, be advantageous to pipe string tripping in；Solve be drilled tubing string tripping in well operations be hampered cause it is not in place under tubing string
Problem, consumption, operating efficiency are high when reducing operation；
(2) in the present invention, top connection is provided with two radial direction through hole up and down, is respectively arranged with oil sac in through hole and oil blocks up,
The function of oil sac is oil storage and equilibrium oil chamber internal pressure, and oiling mode be vacuum oil, from oil it is stifled from oiling when, lubrication thrust
Cylinder roller bearing and self-aligning thrust roller bearing, when being separated each other with bottom in upper end of the present invention, it ensure that it each other
Between rotate against.
(3) in the present invention, spring, thrust ball bearing and interior are from top to bottom disposed between splined shaft and spring strut
Set, inner sleeve bottom is fixedly connected with spline body, overcoat and piston cylinder etc., and shear pin is cut when suppressing, spline body, inner sleeve,
Overcoat and piston cylinder be stressed influence along lower mandrel commutate track elongated slot move up, compression spring, due to spring after pressure release
Effect feather key move to commutation track short groove, splined shaft is engaged with spline body, upper and lower end of the invention lock
Tightly, the moment of torsion for being applied to upper end of the present invention transmits downwards so that upper and lower end synchronous rotary, tubing string tripping in is in place
Afterwards, the present invention can be achieved to be smoothly detached with running string, goes out the present invention.
(4) present invention is by the commutation Track desigh of lower mandrel, can repeatedly be realized by suppressing the present invention upper end and
Conversion between bottom " locking " and " separation " rotation, there is applicability height, function uniqueness.
