Background technique
As the whole world is to the rapid growth of petroleum resources demand, the depth of drilling well and the complexity on stratum are higher and higher,
Especially in the new exploratory area of some shale gas, oil-gas reservoir buries that depth, stratum is hard, abrasiveness is strong low with rate of penetration, and stratum is to PDC
Drill bit apply excessive obstruction torque cause PDC drill bit be easy it is frequent brake phenomenon occurs, so as to cause drill bit and drilling tool
High speed rotation and torsional oscillation cause drill bit to collapse tooth, damage, the disconnected de-, downhole well tool of drilling tool (such as rotary steering system and brill system of hanging down
System) and measurement while-drilling instrument damage, seriously affect drilling efficiency.
Summary of the invention
It is an object of the invention to: it provides that a kind of structure is simple, and practicability is good, stratum pair in drilling process can be effectively prevent
PDC drill bit apply excessive obstruction torque cause PDC drill bit be easy it is frequent brake phenomenon occurs, cause drill bit collapse tooth, damage,
The tool for preventing torque-on-bit excessive of drilling tool disconnected de-, downhole well tool and measurement while-drilling instrument damage.
The technical scheme is that
A kind of tool for preventing torque-on-bit excessive；Including top connection, disc spring, tapered sleeve cylinder, push jack, transmission shaft and output
Axis；It is characterized by: transmission shaft threaded upper ends are equipped with top connection, transmission shaft lower end is set with output shaft, is set on transmission shaft
There is tapered sleeve cylinder, disc spring is provided between tapered sleeve cylinder and top connection, mounting hole, activity in mounting hole are evenly equipped on the circumference of transmission shaft
Push jack is installed, one end of push jack and output shaft connect, and the other end and tapered sleeve cylinder of push jack connect.
Arc groove is evenly equipped on output shaft circumference corresponding with push jack.
The push jack end contacted with output shaft is circle.
The transmission shaft and output shaft is respectively diameter-changing body, and sealing element is provided between transmission shaft and output shaft.
The push jack is T-shaped.
The contact face of the push jack and tapered sleeve cylinder is respectively slope surface, is slided and is connected by slope surface between push jack and tapered sleeve cylinder
It connects.
The mounting hole and push jack quantity is respectively 4.
The beneficial effects of the present invention are:
The tool for preventing torque-on-bit excessive, structure is simple, and practicability is good, in the course of work, once output shaft by
Torque it is excessive when, push jack is exited out of output shaft arc groove, between push jack and output shaft i.e. can produce opposite rotation, by
This avoids output shaft lower part drill bit and brake phenomenon occurs, so that drill bit be avoided to brake the damage to drill assembly, extends brill
Has combined service life；When the torque that output shaft is subject to is normal value, push jack clamps output shaft, and transmission shaft drives output shaft to turn
It is dynamic, that is, it can guarantee the normal drilling of drill bit.

Specific embodiment
The tool for preventing torque-on-bit excessive includes top connection 1, disc spring 3, tapered sleeve cylinder 2, push jack 4, transmission shaft 5 and output
Axis 7；5 threaded upper ends of transmission shaft are equipped with top connection 1, and 5 lower end of transmission shaft is set with output shaft 7.Transmission shaft 5 and output shaft 7 divide
Not Wei diameter-changing body, sealing element 6 is provided between transmission shaft 5 and output shaft 7 with prevent the impurity in pit shaft by transmission shaft 5 and output
Enter drilling fluid runner between axis 7.
It is set with tapered sleeve cylinder 2 on transmission shaft 5, disc spring 3 is provided between tapered sleeve cylinder 2 and top connection 1,5 upper end of transmission shaft
It is evenly equipped with mounting hole on circumference, is movably installed with push jack 4 in mounting hole, the quantity of mounting hole and push jack 4 is respectively 4.
Push jack 4 is T-shaped；Arc groove 8 is axially evenly equipped on 7 circumference of output shaft corresponding with push jack 4.One end of push jack 4
It is connected with output shaft 7,4 end of push jack contacted with output shaft 7 is circle.The other end of push jack 4 is contacted with tapered sleeve cylinder 2；
The contact face of push jack 4 and tapered sleeve cylinder 2 is respectively slope surface, is slidably connected between push jack 4 and tapered sleeve cylinder 2 by the cooperation of slope surface.
The top connection of the tool is used for jointed rod, and output shaft 7 is for connecting drill bit；Under normal operating conditions, push jack 4
End is located in the arc groove 8 of output shaft 7, and push jack 4 drives output shaft 7 to rotate, and there is no opposite between output shaft 7 and push jack 4
Rotation；In the course of work, when the obstruction torque for passing to output shaft 7 by drill bit is normal value, disc spring 3 has sufficiently large thrust
Tapered sleeve cylinder 2 is resisted, thus the tapered sleeve cylinder 2 that can not be moved up resists push jack 4, push jack 4 can not move radially, thus the rotation of transmission shaft 5
Torque can pass to output shaft 7 by push jack 4, drive bit drilling by output shaft 7 (referring to attached drawing 1-3).
When the obstruction torsional forces for passing to output shaft 7 by drill bit is excessive, push jack 4 is obstructed torsional forces out of arc groove 8
It releases referring to attached drawing 4, can relatively rotate between output shaft 7 and push jack 4 at this time, during push jack 4 is extruded, due to
It is slidably connected between push jack 4 and tapered sleeve cylinder 2 by the cooperation of slope surface.Push jack 4 generates a upward thrust to tapered sleeve cylinder 2, compels
It moves up tapered sleeve cylinder 2 and squeezes disc spring 3；When the obstruction torque for passing to output shaft 7 by drill bit is reduced to normally by excessive
When value, disc spring 3 resets and pushes 2 downlink of tapered sleeve cylinder, so that push jack 4 be pushed to move radially, it is made to be re-inserted into output shaft 7
In arc groove 8, the rotation torque of transmission shaft 5 is normally transmitted again, and drill bit restores normal drilling state.
The tool construction for preventing torque-on-bit excessive is simple, and practicability is good, in the course of work, can effectively prevent drilling well
Stratum, which applies excessive obstruction torque to drill bit, in journey causes drill bit to be easy frequent generation brake phenomenon, and then drill bit is caused to collapse
The problem of tooth, damage, the disconnected de-, downhole well tool of drilling tool and measurement while-drilling instrument damage.Extend drill assembly uses the longevity
Life；It is installed and used especially suitable for drilling tool.
