Abstract

The invention relates to a mud turbo alternator, which is used for providing power supply for the drilling instruments in the mine and comprises a turbine, a turboshaft, a sliding bearing, a magnetic coupling outer magnet rotor, a shielding case, a magnetic coupling inner magnet rotor, a generator and a case; A guide pulley for guiding the mud is arranged above the turbine; the inner magnet rotor is arranged in the upper part of the magnetic coupling outer magnet rotor and is coaxially connected with the generator; the shielding case is arranged between the outer magnet rotor and the inner magnet rotor; A standby high-temperature battery which is used when the generator is in failure or the pump is stopped is arranged in the upper air cavity inside the case. The invention has the advantages that the device is the complete non-contact power transference, the complete static seal, the seal is safe and reliable, the hydraulic vibration is small, the pressure is even, the hydraulic performance of the worm wheel is good; additionally, the mud turbo alternator is provided with a standby battery, therefore,, the operation is stable and reliable, the service life of the generator is long and the technology capability is good and the cost is low.

Description

technical field [0001] The invention relates to a mud turbine alternator, which belongs to the technical field of generators, and is an auxiliary equipment for underground drilling equipment in oil drilling engineering, and is used to provide power for downhole drilling instruments. Background technique [0002] With the widespread application of geosteering technology, logging-while-drilling technology and closed-loop drilling technology in the oilfield development process, the downhole measurement and control instrument system requires sufficient energy supply as a guarantee. At present, the technical solutions for the power supply of wireless measuring instruments while drilling in the drilling industry include: 1) Using lithium batteries for power supply, but relying entirely on lithium batteries has many disadvantages, such as limited energy and temperature ranges, poor safety, and pollution to the environment. High cost of use. 2) The downhole mud generator is used fo...
