DOWNHOLE MEASUREMENT ASSEMBLY, TOOL AND METHOD

摘要

A downhole measurement assembly, tool, and method is provided. The downhole measurement assembly includes at least one drill collar 220 having at least one compensation portion and at least one force portion with a load path 239 therethrough. The compensation portion has a different dimension from the force portion. The assembly also includes a plurality of compensation sensors 230.1, 230.2 positionable about the compensation portion to measure downhole tool pressures applied thereto, and a plurality of force sensors 230.3, 230.4 positionable about the force portion to measure downhole forces applied thereto. The compensation sensors and the force sensors are positionable about the drill collar(s) 220 in a strain configuration along the load path 239 whereby the measured downhole tool pressure is isolatable from the measured downhole forces on the drill collar(s).
