CONDUCTIVE FLUID FLOW LOGGING TOOL

摘要

An inspection tool for a casing having an interior wall. The inspection tool comprising a tool body shaped to fit within the casing; an arm rotatably coupled to the tool body, the arm having a near end proximate the tool body and a distal end apposite the near end. The distal end of the arm is rotatable azimuthally along and adjacent to the casing interior wall. The inspection tool also including an electromagnetic sensing device mounted on the distal end of the arm. The sensing device is oriented to sense a radial flow of conductive fluid through the casing interior wall, while being relatively insensitive to radial nonconductive fluid flow and to fluid flow in a central region of the casing.
