BOREHOLE INSTRUMENT FOR BOREHOLE PROFILING AND IMAGING

摘要

A borehole instrument includes a housing sized and shaped to fit inside a borehole, at least one image sensor disposed within the housing and configured to capture images of an inside wall of the borehole, at least one illumination light source disposed within the housing and configured to illuminate the inside wall of the borehole, a laser light source disposed within the housing and configured to emit laser light towards the inside wall of the borehole, a data processing subsystem coupled to the image sensor and configured to receive image data from the image sensor, the image data representative of images of the inside wall of the borehole. The data processing subsystem is further configured to capture borehole profile data from images containing laser light reflected from the inside wall of the borehole.
