BOREHOLE IMAGING SYSTEM FOR CONDUCTIVE AND RESISTIVE DRILLING FLUIDS

摘要

A borehole imaging tool for use in a wellbore penetrating an earth formation includes a pad hingedly connected to a collar, a sensor array carried by the pad, and a n urging assembly in connection between the pad and the collar for extending the pad toward a wal l of the wellbore. The imaging tool is compatible with both oil-based and water-based drilling fluids.
