Turbodrill is a kind of common petroleum gas and geological drilling mud motor, and its effect is by drilling well
The fluid pressure energy of liquid is changed into mechanical energy, and driving drill bit rotates to crush bottom rock.The output characteristics of turbodrill
Parameter (pressure drop P, rotating speed n, moment of torsion M and power N) is closely related with drilling fluid displacement Q, drilling fluid density γ etc., wherein, turbine
Pressure drop P and drilling fluid displacement Q is into quadratic relationship, and be directly proportional linear relation to drilling fluid density γ；Rotating speed n and drilling fluid displacement Q
Be directly proportional linear relation；Moment of torsion M and drilling fluid displacement Q is into quadratic relationship, and be directly proportional linear relation to drilling fluid density γ；Power
N and drilling fluid displacement Q is into cubic relationship, and be directly proportional linear relation to drilling fluid density γ.Obviously, drilling fluid displacement Q, drilling fluid
Density γ can significantly affect the output characteristics parameter (pressure drop P, rotating speed n, moment of torsion M and power N) of turbodrill.
At present, using rate of penetration during turbodrill progress combined drilling often quickly (sometimes more than 50~100m/h),
Shaft bottom drill bit broken rock amount is very big, if landwaste will be crushed not in time clears shaft bottom, excludes well, inherently causes sand setting bit freezing
Deng drilling complexity or accident.In order to ensure downhole safety, generally using drilling fluid displacement Q is increased, increase annular space drilling fluid returns speed
To improve landwaste lifting efficiency, it is to avoid accumulation of the landwaste in well.Due to existing turbodrill motor spindle and locking nut
It is not hollow, drilling fluid displacement Q increase can increase considerably turbodrill pressure drop P, drilling pump real work pump pressure can
It can exceed its rated pump pressure, drilling pump is caused to damage.In addition, being frequently encountered abnormal pressure stratum in drilling process, it is
Equilibrium strata pressure is, it is necessary to increase considerably drilling fluid density γ.Equally, drilling fluid density γ increase also can bore turbine
Has the increase of pressure drop P straight lines, drilling pump real work pump pressure may exceed its rated pump pressure.Therefore, it is badly in need of a kind of drilling fluid row
Measure the adjustable turbodrills of Q.
Utility model content
The purpose of this utility model is that there is provided a kind of turbodrill with nozzle is hollow for the drawback of prior art
Motor, to solve the problem of existing turbodrill drilling fluid displacement can not be adjusted.
To achieve the above object, the technical scheme that the utility model is used is：
A kind of hollow motor of turbodrill with nozzle, including top connection, turbine motor main shaft, locking nut, main shaft
Adjust packing ring, housing adjustment packing ring, radial direction alignment bearing moving-coil, radial direction alignment bearing Jing Quan, turbine stator, turbine rotor and whirlpool
Wheel motor housing；The top connection is arranged on turbine motor housing upper end, in turbine motor inner walls from top to bottom successively
Assembling shell adjustment packing ring, radial direction alignment bearing Jing Quan and turbine stator；The locking nut, main shaft adjust packing ring, radially helped
Positive bearing moving-coil and turbine rotor are sleeved on turbine motor main shaft successively from top to bottom, turbine rotor cloth relative with turbine stator
Put, the locking nut is fitted in the upper end of turbine motor main shaft；It is particular in that：The locking nut and turbine motor
Main shaft is hollow structure, and disconnectable nozzle is equipped with the endoporus of locking nut.
Gear is also set up in a kind of hollow motor of turbodrill with nozzle as described above, the endoporus of the locking nut
Circle, the back-up ring is located above the nozzle.
A kind of hollow motor of turbodrill with nozzle as described above, the inner hole wall of the locking nut is provided with card
Groove, the back-up ring is circlip for hole, and the circlip for hole is installed in the neck of locking nut inner hole wall.
A kind of hollow motor of turbodrill with nozzle as described above, the inner hole wall of the locking nut is provided with interior spiral shell
External screw thread with the screw-internal thread fit is set on line, the back-up ring outer wall, and back-up ring is connected through a screw thread structure and is arranged on locking
On the inner hole wall of nut.
The utility model is after adopting the above technical scheme, the effect with following technological progress：
Turbine motor main shaft and locking nut are designed to hollow structure by the utility model, and are set in locking nut endoporus
Interchangeable nozzles and circlip for hole or threaded back-up ring are equipped with, the spray with different-diameter size can be changed in situ of drilling well
Mouth, to meet drilling fluid displacement adjustment needs.When needing increase discharge capacity Q, nozzle of small diameter can be more replaced with to major diameter nozzle,
Increased drilling fluid is allowed to pass through turbodrill by turbine motor inner hole of spindle；, it is necessary to subtract when drilling fluid density is increased substantially
During small drilling fluid displacement Q, drilling well by turbine motor inner hole of spindle can be allowed by major diameter nozzle exchange into slightly smaller diameter nozzle
Liquid measure reduces, it is ensured that pass through the minimum drilling fluid displacement of turbine rotor leaf grating.So, the output characteristics parameter of turbodrill is not
Have and change by a relatively large margin, drilling pump actual working pressure is less than its rated pump pressure or drilling pump actual power is less than its specified pump
Power, so as to ensure that the safe handling of drilling pump.
