APPLICATION OF THE EMPIRICAL MODE DECOMPOSITION METHOD TO GYROSCOPIC SYSTEMS BY AN EXAMPLE OF A HYBRID INCLINOMETER

摘要

A hybrid inclinometer developed in the Institute of Applied Mechanics named after Academician Ⅵ Kuznetsov uses small-sized low-accuracy fiber optic gyroscopes produced by "Fizoptika" as a gyroscopic sensor. A number of physical factors affect the precision of fiber-optic gyroscopes while the inclinometer downhole tool moves down the hole in continuous mode of operation. A method of empirical mode decomposition is proposed to process the data obtained from the fiber-optic gyro to improve the accuracy of the trajectory of the hole when the inclinometer working in continuous mode.
