Algorithms and design of longitudinal gyroinclinometer for vertical parts of wellbores

Abstract

Existing designs and ideal algorithms of various types of gyroinclinometers (GI) (including those earlier rejected designs) are analyzed to study the errors of continuous survey of vertical parts of wellbores. Modernized structure and new algorithms using the structural redundancy specially created in longitudinal GI are proposed. Analytical study of the accuracy of synthesized scheme is accompanied by abundant mathematical modeling and results from practical operation.
