AZIMUTH TRANSDUCER OF WELL INCLINOMETER Russian patent published in 1994 - IPC

FIELD: measurement of space position of wells. SUBSTANCE: transducer has transparent spherical float 6 with circular magnet 7 and hemispherical plate 8 whose optical density varies in proportion to angular coordinate. Float has rotation shaft coinciding with longitudinal axis of transducer. Light source 2 and photodetector 3 are located on opposite sides of float 6 and displaced from rotation axle of float 6 through angle in the order of 45 deg. Well azimuth is determined by amplitude of output signal of photodetector. EFFECT: higher efficiency. 3 dwg
