METHOD AND CONTROL OF OPERATING MODE OF TELEMETERING SYSTEM POWER GENERATOR Russian patent published in 2008 - IPC E21B47/02 

FIELD: mining engineering, oil industry.

SUBSTANCE: invention refers to directional drilling of oil and gas wells, specifically to power generators of well logging equipment connected to bottomhole telemetering systems. Control of operating mode of generator supplying power for telemetering system includes generator mounted over electric separator inside of protective casing equipped from upper side with substitute for drill pipe core mounting. Generator is adjusted in such a way that its turbine is adjusted inside of substitute equipped with control screw sleeve moving axially lower part of which is designed with collar sealed on inner surface of substitute. Upper part of control sleeve is designed with flanges entering recesses of retainer insert. Lower part of inner surface of control sleeve is expanding, and outer surface of retainer insert in turn is furnished with flanges entering recesses of substitute inner surface. Technological result lies in smooth preset adjustment of generator turbine rotary speed to provide rated voltage at generator outputs, improvement of reliability of housing parts included in drill pipe core structure.

EFFECT: smooth adjustment of generator turbine rotary speed to provide rated voltage at generator outputs, improvement of reliability of housing parts included in drill pipe core structure.
