Visit the main well type of exploitation.For straight well, in these special wells, underground drill stem state is more complicated, needs to obtain
Downhole parameters more various, to down-hole information transmission transfer rate, transmitted data amount require higher.Current down-hole information without
Sonic transmissions technology in line transmission technology presents relatively due to advantages such as efficiency of transmission are high, cost is relatively low and applied widely
Good growth momentum, if the method can be widely used in drilling engineering field, it must significantly promote the reality of down-hole process
Time monitoring and intelligentized control method realize paces.But, in drilling process, drill bit breaks the products such as rock, circulation of drilling fluid and rig work
Sound carrier interference problem is had not been able to solve very well by raw noise all the time, finally affects the reality of down-hole information sound transmission technology
Existing.Among many noises, because turn on pump makes power drilling tool work, thus drive drill bit and the borehole wall or the collision of well, friction
The noise produced because its intensity is big, the characteristic of bandwidth and become the main interference factor of down-hole information transmission sound carrier.If
Enable to that power drilling tool during deviational survey quits work, power drilling tool is started working when creeping into, then power drilling tool creeps into noise
Can effectively eliminate.Therefore, research and development power drilling tool working state control instrument to control mud motor according to drilling state
Duty is to the suppression of noise during directional well deviational survey and evades the most meaningful, the reality to down-hole information sound transmission technology
Now there is important function.
Summary of the invention
The problems referred to above existed for prior art, the present invention provides a kind of power drilling tool working state control instrument, should
Instrument enables to stop during deviational survey power drilling tool work, starts power drilling tool and creeps into, thus evade down-hole information sound when creeping into
The noise of the transmitting procedure drill bit sliding wear borehole wall, it is achieved the purpose of transmission that sound carrier is noiseless.
For achieving the above object, the present invention uses following proposal:
Power drilling tool working state control instrument, including: instrument mandrel, anti-impact ring body, torsion pass pressure release cylinder, anticreep snap ring and
Anticreep short circuit；Anti-impact ring body, torsion pass pressure release cylinder, anticreep snap ring and anticreep short circuit it is provided with the most according to this outside instrument mandrel.
Relative to prior art, the present invention has a following beneficial effect:
1, can need to start and stop the duty of power drilling tool according to the process of measurement, thus fundamentally suppress power
Drilling tool itself and power drilling tool drive the correlated noise that drill bit causes with shaft bottom and borehole wall effect；
2, tool construction is simple, length is short, does not affect power drilling tool and the work of measurement while drilling instrument, be of value to during use
Work long hours, beneficially onsite application；
3, installing and easy to use, easy to maintenance, safety is good, it is possible to meeting works long hours dislike in down-hole slightly environment it
In requirement.

Power drilling tool working state control instrument control power drilling tool duty principle:
1, deviational survey data sound transmission process:
As it is shown in figure 1, during deviational survey, drill bit lift-off shaft bottom, because of frictional force and action of gravity, power drilling tool pulls torsion pass
Pressure release cylinder 4 moves downward relative to instrument mandrel 1 with the body of threadeding of anticreep short circuit 7, the power drilling tool connection on instrument mandrel 1
Within passage flow duct 8 enters anticreep short circuit 7, the runner towards power drilling tool stator with rotor cavity is blocked, and power drilling tool stops
Rotate, meanwhile, mandrel shunting duct 10 and the tune sap cavity 405 on torsion pass pressure release cylinder 4 and annular space discharge orifice on instrument mandrel 1
9 are connected, and drilling fluid is all by mandrel shunting duct 10 and the tune sap cavity 405 on torsion pass pressure release cylinder 4 and annular space discharge orifice 9 structure
The UNICOM space become enters annular space, it is achieved circulation, by said process, on the premise of ensureing drilling fluid normal circulation, stops
Power drilling tool work, eliminates power drilling tool and rotates and power drilling tool drives the drill bit sliding wear borehole wall or the noise in shaft bottom.
2, in normal drilling well drilling process:
As in figure 2 it is shown, in normal drilling well drilling process, bottomhole pressurized, top drill thrust promotes torsion pass pressure release cylinder 4
Move upward relative to instrument mandrel 1 with the body of threadeding of anticreep short circuit 7, the power drilling tool UNICOM runner 8 on instrument mandrel 1
Releasing outside anticreep short circuit 7, the runner towards power drilling tool stator with rotor cavity is got through, and it is fixed that drilling fluid flows into power drilling tool
Cavity between son and rotor, meanwhile, mandrel shunting duct 10 and the tune sap cavity 405 on torsion pass pressure release cylinder 4 and ring on instrument mandrel 1
Empty discharge orifice 9 is separated, and enters in slipper seal end face 404, and drilling fluid is shunted duct 10 by mandrel, adjusted sap cavity 405 and ring
The runner that empty discharge orifice 9 enters annular space is blocked, thus ensures that all drilling fluids enter in power drilling tool cavity volume, power drilling tool
Start to rotate, pass through said process, it is achieved that normal drilling process medium power drilling tool rotates and power drilling tool drives drill bit to break rock
Creep into.
