Borehole Image Measurements / Изображение скважинных испы

Dipmeter measurements have evolved through two major stages. The first tools were mechanical systems. The tool orientation was determined from a pendulum and magnetic compass. Both of these were subject to limitations due to inherent friction. The three-arm, three-button CDM (Continuous Dipmeter) yielded one three-point solution to a bedding plane. The four-arm, four-button HDT (High-Resolution Dipmeter Tool) permitted four three-point solutions to each bedding plane.
