SYSTEM FOR DETERMINATION OF FACE HOLE PARAMETERS Russian patent published in 2003 - IPC

FIELD: gyroscopic and navigation instrumentation engineering, particularly, instruments for monitoring of face hole parameters. SUBSTANCE: system has well monitoring module including unit of primary information transducers in the form of three accelerometers with orthogonal sensitive axes, three magnetometers with orthogonal sensitive axes, three gyroscopic angular velocity meters with orthogonal sensitive axes, and information processing unit, three micromechanical gyroscopes whose sensitive axes are parallel to probe axis, two magnetometers installed so that sensitive axes of four magnetometers located in plane perpendicular to probe longitudinal axis, are perpendicular to probe longitudinal axis and angles of 90 deg are between them. Four magnetometers are located over periphery, and sensitive axis of the fifth magnetometer is parallel to probe longitudinal axis. System also has metering device of logging cable length, logic unit and computer of information preliminary processing. Body of unit of primary information transducers is made of nonmagnetic materials. EFFECT: increased accuracy of determination of face hole parameters. 4 dwg
