Abstract
The Scientific-production enterprise of geophysical equipment “Looch” develops and manufactures LWD telemetry systems used in the process of drilling oil and gas wells. They include an orientation sensor (inclinometer) that estimates the position of the device in the well based on signals from three accelerometers and three magnetometers. System modules operate at high temperatures (up to 120 °C), and temperature drift compensation is required to ensure the specified orientation measurement error. This paper provides estimates of allowable drifts of sensor readings, a temperature polynomial model of accelerometers and magnetometers, and a compensation technique. An experiment was carried out, the results of which determined the suitability of the model and methodology used.
