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