Formation evaluation tool. |
摘要 |
<p>A tool for measuring the mechanical properties of a formation through which a borehole has been drilled, comprising a tool body capable of being lowered into a borehole, the tool body having pads mounted on moveable arms, each pad carrying a PDC type cutter which is urged against wall of the borehole so as to cut into the formation; transducers are provided for determining the depth of cut made by the cutter and for determining the resistance of the rock to cutting. The tool is connected to a wireline, enabling the cutter to be moved through the formation and the data from the transducers to be returned to the surface for analysing the depth of cut and resistance to cutting to determine the mechanical properties of the rock. <IMAGE></p> |
