Abstract The attitudes of stratum obtained directly from imaging logging images are apparent values, and are related to the logging tool coordinate system. For the case of tilted borehole, deviation correction for the attitude values should be executed. In this paper, an algorithm is presented to correct the attitude values derived from imaging logging with borehole deviation data. As a practical example, the approach is applied to imaging logging data processing of the second pre pilot drillhole of Chinese Continental Scientific Drilling in North Jiangsu Province.
