ABSTRACT
Generating electricity by downhole turbine generator is one of the main methods to provide power supply for the downhole measuring and controlling in the drilling process of oil and gas production. This study has analyzed three kinds of structure of the existing turbine generators, including the common unsealed structure, the axial magnetic drive structure and cylindrical magnetic drive structure. By combining the dynamic seal compensating protection technology and the magnetic drive technology, the supporting high-speed bearing of the rotating turbine and the dynamic seal components has been sealed with compensating protector and high speed rotating of the turbine has been transmitted to the rotor of the generator without contact by the magnetic drive which can isolate the generator from the power mud fluid completely, improve the working condition of the turbine generator and increase the service life and reliability of the moving parts of turbine generator. The study also discusses the material selection of the key parts.
