ARM-based attitude measurement system design of guided drilling tool

Abstract

Accurate measurement of attitude parameters (inclination angle I, tool face angle T, azimuth angle A) of downhole tools is one of the key technologies in the whole guided drilling process. Improving the measurement accuracy of attitude parameters can shorten the drilling cycle and reduce the drilling risk. Based on the existing drilling tool attitude measurement theory, this paper proposes a design scheme of drilling tool attitude data acquisition and processing system based on ARM. The system takes Samsung Exynos4412 processor as the core controller, co-ordinates the control between various functional modules, completes the acquisition, processing and calculation of attitude angles such as I, A and T, and replaces the traditional scheme of ‘ PC + data acquisition card’.
