10, a kind of New well drilling torque increase square of the invention, which disappears, quivers except vibratory tool, is connected among drilling rod, drill collar and drill bit
Position, in lower going-into-well.
One of present invention New well drilling torque increase square, which disappears, to quiver except vibratory tool, by shipbuilding industry, the speed change of automobile industry
Case principle, upgrading, transformation eliminate sun gear 12, planetary gear 9, gear ring 13 and are fixed from for necessary one in this
The element of rotary motion simultaneously, is applied to oil drilling industry, by sun gear 12, planetary gear 9, gear after innovation transformation invention
Enclosing 13 this innovation is integration, interacts interlocking structure；Play drilling well torque increase square disappear quiver except vibratory drilling speed-raising
Effect improves drilling efficiency, reduces the purpose of operating cost to reduce the intensity of drilling well labour.
Compared to the prior art, a kind of New well drilling torque increase square provided by the invention, which disappears, quivers except vibratory tool, has as follows
Advantage:
1, a kind of New well drilling torque increase square, which disappears, quivers except vibratory tool, and planetary gear mechanism is utilized and transmits and increases torque
Feature.
2, a kind of New well drilling torque increase square, which disappears, quivers except vibratory tool, and gear ring, reset spring is utilized can only be certain
In rotation angle range repeatedly Periodic Rotating, reset the characteristics of.
3, a kind of New well drilling torque increase square, which disappears, quivers except vibratory tool, if reset spring fails, tool is also only comparable to
One drill pipe nipple, does not influence after follow-up hole.
4, a kind of New well drilling torque increase square, which disappears, quivers except vibratory tool, and it is mutual that any 2 elements in planetary gear mechanism are utilized
After mutually locked, all elements as an element it is whole with identical angular speed, identical revolving speed together with drilling rod, drill collar
The characteristics of synchronized rotation.
5, a kind of New well drilling torque increase square, which disappears, quivers except vibratory tool, be utilized planetary gear, planet carrier, planetary gear shaft,
Lower contact can only in certain rotation angle range repeatedly Periodic Rotating, reset, by gear ratio functional relation increase turn round
Square output still, cannot be continuous by the broached-tooth design and lower contact broached-tooth design of gear ring lower part and the constraint of reset spring
Rotation, does not finally reduce rotating cycle continuously by the functional relation of gear ratio, i.e., does not slow down.
Working principle of the present invention is as follows:
Whenever output element of the planet carrier as planetary gear mechanism, planetary gear mechanism will play reduction of speed torque increase square
Effect.A kind of New well drilling torque increase square of the invention, which disappears, to quiver except vibratory tool together with drilling rod, drill collar in lower going-into-well, ground drill
The torque of input is transmitted to planetary gear 9, planet tooth by drilling rod, drill collar, top connection 1,12 input torque of sun gear, torque again
Wheel shaft 11, planet carrier 10 increase torque by the functional relation of gear ratio；Be reset spring 16 and the broached-tooth design of gear ring 13 is total
With rotating in certain angular range under constraint, decreasing transmission is realized；At this moment planetary gear 9 starts rotation, and and planet carrier
10 start to revolve around sun gear 12 jointly, and the revolving speed of planet carrier 10 reduces, this causes the torque of planet carrier 10 to increase, after increase
Torque be transmitted to lower contact 2, then be output to drill bit.
Since there are the constraint of reset spring 16, broached-tooth design, gear ring 13 can only be in certain rotation angle range
Periodic Rotating, reset repeatedly；Within this range, the torque of output is to increase torque output by the functional relation of gear ratio；
But due to the constraint by reset spring 16, broached-tooth design, gear ring 13 cannot continuously be rotated in deceleration: i.e. can only be certain
Angle in be rotated in deceleration.
Drill bit completes the process of cutting at one time rock, and once starts increase torque, maximum output torque value, and drill bit is complete
At rock cutting, after suffered rock resistance discharges suddenly, process that output torque is zeroed again.
After maximum output torque value, if drill bit also fails to complete first time rock cutting: drilling rod, the rotation of drill collar are used
Property kinetic energy, top connection 1 will be continued to output, sun gear 12 continues that planetary gear 9, planet carrier 10, planetary gear shaft 11 is driven to revolve
Turn, the reset spring 16 placed between the broached-tooth design of 13 lower part of broached-tooth design and gear ring of lower contact 2 is promoted to continue
Compression, mutually hits with the sawtooth end face of gear ring 13 until the sawtooth end face of lower contact 2 and is overlapped, and impact force is turned round plus maximum
Square is transmitted to lower contact 2 with joint efforts, then exports and give drill bit second of rock cutting.
If drill bit also fails to complete second of rock cutting: in the sawtooth end face of lower contact 2 and the sawtooth of gear ring 13
After coincidence is mutually hit in end face, this two pieces element is locked, as a result: top connection 1, sun gear 12, planetary gear 9, planet carrier 10,
After planetary gear shaft 11, gear ring 13, reset spring 16,2 integral components of lower contact are locked mutually, institute in planetary gear mechanism
Have element as an element it is whole with drilling rod, drill collar all with identical angular speed, identical revolving speed together with rotate at the same speed,
It quivers finally, drilling rod, drill collar and drilling well torque increase square disappear except vibratory tool constitutes an entirety, all rotatory inertia kinetic energy is converted to
Potential energy, then export and complete third time rock cutting to drill bit.
One of present invention New well drilling torque increase square, which disappears, to quiver except vibratory tool, greatly increases bit speed, saves
Drillng operation expense guarantees that petroleum, the drilling speed of natural gas, coal bed gas or shale gas rock plays crucial effect,
It greatly enriches, realize a possibility that multiple, Ji Shici, several hundred secondary repetitions enter well drilling speed operation.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
