Abstract

For måling av en forskjøvet stabilisatoranordnings orientering i en omgivelse nede i et hull. En aksel roterer i forhold til stabilisatoranordningen, og signalutløsere er anordnet på kjente steder på både den roterende aksel og stabilisatoranordningen. Når signalutiøseme på hver komponent er brakt i flukt med hverandre utløses et signal og en tykkpuls genereres. Tuningen av de genererte signaler benyttes sammen med den målte orientering av akselen, oppnådd ved anvendelse av en vinkelmålesensor, så som et akselerometer og/eller et magnetometer, for å beregne den forskjøvne stabilisatoranordnings orientering.For measuring an offset stabilizer device orientation in a downhole environment. A shaft rotates relative to the stabilizer, and signal triggers are provided at known locations on both the rotating shaft and the stabilizer. When the signal utilities on each component are aligned with each other, a signal is triggered and a thick pulse is generated. The tuning of the generated signals is used in conjunction with the measured orientation of the shaft, obtained using an angle measuring sensor, such as an accelerometer and / or a magnetometer, to calculate the orientation of the offset stabilizer device.
