OPERATION MODE REGULATOR FOR POWER SUPPLY GENERATOR OF WELL TELEMETRIC SYSTEM DEVICE Russian patent published in 2008 - IPC E21B47/12 F03B15/00 

FIELD: petroleum industry.

SUBSTANCE: invention relates to controlled-angle drilling of oil and gas wells, namely to power supply generators of well instrumentation-components of face telemetric systems. The operation mode regulator for power supply generator of the well telemetric system device contains the generator mounted over the electric baffle inside the protective enclosure with the adapter for fixing to the drilling pipes string mounted on the top side of the envelope. A crosspiece with windows for passing mud fluid is fixed inside the adapter; a rod is secured in the middle of the crosspiece. A guiding device is mounted on the rod so that it can move in axial direction. The rod has stepped internal boring and thread and the guiding device is fixed through longitudinal windows provided in the rod to the spring-loaded bush. The axial position of the bush is adjusted by the screw that passes through the central opening in the bush. The screw is mounted on the thread provided in the internal boring of the rod.

EFFECT: possibility of smooth control of the rotation speed of the generator turbine for obtaining rated voltage at its outputs, increased reliability of the structural components of the drilling pipe strings.
