Embodiment 9
Such as Fig. 6, in the present embodiment, conversion compensation assembly 500, including passing spool are additionally provided on the basis of embodiment 7
5001-01, electric rotors 5002-01, conducting stator 5003-01, centralizer 5004-01, compensation and electric installation 5005-01 and
Conversion compensation shell 5006-01, compensation are mounted on conversion compensation shell by centralizer 5004-01 with electric installation 5005-01
In 5006-01, electric rotors 5002-01 is connected to conducting stator 5003-01, and is mounted on compensation and electric installation together
In 5005-01, the both ends passing spool 5001-01 are axially connect with anti-lost axis 4001 and electric rotors 5002-01 respectively, passing spool
A cable-through hole, power supply and signal wire are drilled among 5001-01 behind cable-through hole, compensation and the inside electric installation 5005-01, directly
It is connected by the centre bore of the end face centralizer 5004-01 and the instrument of upper end.
Helicoid hydraulic motor of the invention is to cross line connection entirely from top to bottom, and helicoid hydraulic motor lower end may be implemented to connect other
Other any independent device for subsurface measuring such as instrument pipe nipple such as nearly drill bit measurement pipe nipple, rotary steering system, and realize power supply and
Signal crosses helicoid hydraulic motor transmission.
The electric rotors 5002-01 converted in compensation assembly 500 and conducting stator 5003-01 in the present invention occur opposite
Rotation, electric data signal pass through in the connecting shaft and anti-lost axis inside compensation and electric installation 5005-01 and anti-lost shell 4004
Heart hole is connected, centre bore inner conductors by rotor bore inside motor assembly 300, universal axle assembly 200 inside
Universal shaft inner hole, then by water cap inner hole, end is then reached by drive assembly 100 and is realized finally from three sections to lower end
Thoroughly connection.Electric rotors 5002-01 is connect with passing spool 5001-01, is drilled among passing spool 5001-01 with cable-through hole, it
It is connected with anti-lost axis 4001 and electric rotors 5002-01, because rotor 3002 is in rotary motion, it may occur that (circumference in transverse direction
On face) bias, passing spool 5001-01 uses the composite material with certain flexibility, and passing spool 5001-01 passes through conduction
After rotor 5002-01 connection, compensation uses cemented carbide material with the inside electric installation 5005-01, and eccentric motion is forced to become
Concentric movement.
The present invention described line from helicoid hydraulic motor upper end (i.e. anti-lost tip side) to the embodiment of helicoid hydraulic motor lower end,
Crossing line is a cable, and power supply, data or signal realize perforation by the cable, and screw rod upper/lower terminal can connect independence
Apparatus elements realize being bi-directionally connected and communicating for the signals such as upper and lower together power supply, data and instruction.It is wanted according to the design of system
It asks, can be single-core line or split conductor as the cable for crossing line.
Drive assembly part, because of design itself and bearing wear, under different bit pressures or formation influence, main shaft 1003-
01 with external shell certain relative motion up and down can occur, be also play, the play will drive coupled inside its
Opposite play can also occur for his component, including connecting shaft；Because internal links the top compensation with electric installation 5005-01 with
Conversion compensation shell 5006-01 is fixed together, therebetween without any relative motion, in electric rotors 5002-01
It is interior to use double layer design, including a housing and inner shaft, realize the length variation of electric rotors 5002-01 in a certain range,
As a kind of scalable pipe nipple, compensation is because of the relative displacement that main shaft 1003-01 or more play occurs.
There are power supply and signal connected to it to cross line in electric rotors 5002-01, crosses line and electric rotors 5002-01 mono-
Rotation is played, line is crossed and is connected with a spring leaf or brush, spring leaf/brush and the conducting ring phase inside conducting stator 5003-01
Place is met, conducting stator 5003-01 is fixed together with centralizer 5004-01, therefore relative motion, rotation occur for rotor and stator
Spring leaf/brush pass through conducting ring realize power supply, semaphore instruction two-way communication.
Anti-lost assembly 400 in the present invention is avoided for preventing because helicoid hydraulic motor falls well risk after lower drilling tool fracture
Scaring accident.Motor assembly 300 mainly includes stator case 3001 and rotor 3002, and mud is pushed by surface mud pump pressure
Dynamic, by the gap of stator interior rubber and rotor, at mechanical kinetic energy, with stator rubber phase occurs the hydraulic conversion of mud for rotor
To rotary motion.The universal shaft housing 2001 of universal axle assembly 200 is angle adjustable or fixed angle curved shell (straight well operation
In straight shell also can be used) angle of shell needs to be adjusted to corresponding camber to meet the construction track requirements of orientation well operations, ten thousand
The decentraction for being used to conduct motor rotor to axis 2002 moves the communicating sports for being converted to lower part.The water cap of drive assembly 100
Most of shunting body is diverted to spindle hole by 1005-01, then is flowed to lower tool inner hole and eventually arrived at drill bit, and bearing is used
In bearing axial direction and radial stress, main shaft is for transmitting torque and forming slurry channel.The main function of water cap 1005-01 be by
Mud runner is gone to spindle hole by its tap hole by top mud, because being full of mud in spindle hole, conducting wire is needed
To be isolated with external mud.Main shaft crosses line protector 1003-01 first is that conducting wire is protected not contact with external mud medium, guarantees
The connectivity of conducting wire, second is that guarantee its working life using Anti-erosion corrosion-resistant material.
The above is only a preferred embodiment of the present invention, rather than its limitations；Although should be pointed out that referring to above-mentioned each
Embodiment describes the invention in detail, those skilled in the art should understand that, it still can be to above-mentioned each
Technical solution documented by embodiment is modified, or equivalent substitution of some or all of the technical features；And this
A little modifications and replacement, do not make the essence of corresponding technical solution depart from the scope of the technical solutions of the embodiments of the present invention.
