INCLINOMETER CALIBRATION STAND Russian patent published in 2023 - IPC E21B47/02 G01B11/26 

FIELD: well production.

SUBSTANCE: metrological support for geophysical and production wells used for telemetric support of drilling processes for oil and gas wells, namely for constructing a well path during drilling with a given accuracy, in particular for determining the zenith and tool faces. The inclinometer calibration stand contains a frame on three supports, two rotating mechanisms in the form of two steering knuckles mounted on it, and a frame with a heat-insulating layer inside and a controlled thermostat outside. The frame is attached to the steering knuckles and has one degree of freedom for rotation in the vertical plane. Two bearings and collets are attached to one edge of the frame, providing clamping of the inclinometer under test and freedom of its rotation around the longitudinal axis along the tool face. A shaft is extended beyond the side wall of the frame, ensuring the transmission of rotation along the tool face to the vernier of the stand.

EFFECT: providing the ability to construct a temperature model when calibrating an inclinometer.
