OVERTURNING INCLINOMETER WITH GYRO SENSORS Russian patent published in 2019 - IPC E21B47/24 

FIELD: soil or rock drilling; mining.

SUBSTANCE: invention relates to devices for measuring inclination and direction of boreholes, particularly to downhole inclination meters. In particular, disclosed is a platform of sensors on gimbal suspension, made with possibility of installation in tool housing, having longitudinal axis, which comprises external gimbal suspension, external angular positioning device connected to external gimbal suspension for rotation of outer gimbal suspension relative to tool housing around axis of rotation of external gimbal suspension; internal gimbal suspension; internal angular positioning device connected to internal gimbal suspension for rotation of internal gimbal suspension relative to external gimbal suspension around axis of rotation of internal gimbal suspension; and gyro sensor connected with internal gimbal suspension. At that, outer universal joint is connected with possibility of free rotation with tool housing. Internal universal joint suspension is connected with possibility of free rotation with an external cardan suspension. Gyroscope has measuring axis, in fact, orthogonal to rotation axis of internal gimbal suspension.

EFFECT: technical result is broader functional capabilities of device.
