The invention relates to the field of petroleum drilling and cementing techniques and particularly relates to a non-magnetic motor. The non-magnetic motor comprises a switching connector, a stator housing, a rotor, a universal shaft assembly and a driving shaft assembly, wherein the switching connector, the stator housing and the rotor are made of a beryllium bronze non-magnetic material; the switching connector is in threaded connection with one end of the stator housing; the other end of the stator housing is connected with one end of the universal shaft assembly; the other end of the universal shaft assembly is connected with one end of the driving shaft assembly; the rotor is arranged in the stator housing and is connected with one end of a universal shaft of the universal shaft assembly; the other end of the universal shaft of the universal shaft assembly is connected with a driving shaft of the driving shaft assembly. Through the non-magnetic motor, the problem of interference of the overall magnetism of the motor on a logging instrument can be solved; the errors of measuring points and drill positions can also be reduced; the measurement accuracy as well as the power and the torque of the motor can be improved.
Description
Technical field
The present invention relates to oil drilling cementing technology field, particularly relate to a kind of without magnetic motor.
Background technology
Well dynamic motor is still the drilling tool of main application both at home and abroad at present, in the industry fields such as oil and gas well drilling, CBM Drilling, geological prospecting, mine probing, assume responsibility for the wellbore construction task of more than 95%.But in drilling process, under existing well, power motor is except the rotating speed providing the broken rock of drill bit and moment of torsion, does not possess the function of other efficient rock-breakings.At present, conventional coal tunnel drilling well mainly adopts φ 73mm motor, and logger interference is produced interference by motor complete machine magnetic, measures point relatively big with the error of bit location, and the accuracy of measurement and the power of motor and moment of torsion can not meet on-the-spot needs.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned technology, and provide a kind of without magnetic motor, solve the problem that logger is disturbed by motor complete machine magnetic.
The present invention for achieving the above object, by the following technical solutions:
A kind of without magnetic motor, it is characterized in that: include adapter, stator case, rotor, universal drive shaft assembly and driving-shaft assembly, described adapter, stator case and rotor all adopt beryllium-bronze non-magnetic material to make, described adapter is connected with the threaded one end of described stator case, the other end of described stator case is connected with one end of described everything axle assembly, and the other end of described universal drive shaft assembly is connected with one end of described transmission shaft assembly；Described rotor is placed in described stator case, and described rotor is connected with the everything axle one end in described everything axle assembly, and the other end of the everything axle in described everything axle assembly is connected with the transmission shaft in described transmission shaft assembly.
Preferably, the everything axle in described everything axle assembly adopts goalpost to seal universal drive shaft.
Preferably, the radial direction of described driving-shaft assembly adopts TC bearing, axially adopts hard alloy and tungsten carbide sintering axle power bearing.
The invention has the beneficial effects as follows: compared with prior art, stator case and the rotor material of this device adapter and motor all adopt non-magnetic material (beryllium-bronze non-magnetic material), universal drive shaft adopts goalpost to seal universal drive shaft, driving-shaft assembly radially adopts TC bearing, axially adopts hard alloy and the axle power bearing of tungsten carbide sintering.Solve the problem that logger is disturbed by motor complete machine magnetic, reduce again the error measuring point with bit location, improve the accuracy of measurement and the power of motor and moment of torsion.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of without magnetic motor, including adapter 1, stator case 2, rotor 3, universal drive shaft assembly 4 and driving-shaft assembly 5, described adapter, stator case and rotor all adopt beryllium-bronze non-magnetic material to make, described adapter is connected with the threaded one end of described stator case, the other end of described stator case is connected with one end of described everything axle assembly, and the other end of described universal drive shaft assembly is connected with one end of described transmission shaft assembly；Described rotor is placed in described stator case, and described rotor is connected with the everything axle one end in described everything axle assembly, and the other end of the everything axle in described everything axle assembly is connected with the transmission shaft in described transmission shaft assembly.
Everything axle in described everything axle assembly adopts goalpost to seal universal drive shaft.The radial direction of described driving-shaft assembly adopts TC bearing, axially adopts hard alloy and tungsten carbide sintering axle power bearing.
Stator case and the rotor material of this device adapter and motor all adopt non-magnetic material (beryllium-bronze non-magnetic material), universal drive shaft adopts goalpost to seal universal drive shaft, driving-shaft assembly radially adopts TC bearing, axially adopts hard alloy and the axle power bearing of tungsten carbide sintering.Solve the problem that logger is disturbed by motor complete machine magnetic, reduce again the error measuring point with bit location, improve the accuracy of measurement and the power of motor and moment of torsion.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
