System and Methodology for Determining Forces Acting on Components

摘要

A technique facilitates measurement of forces resulting from a variety of loads, stresses, temperatures, or other sources. In an embodiment, the system comprises a load cell constructed with channels extending into a component which may be subjected to forces. Sensors cooperate with the channels to detect changes in volume of the channels as an indicator of the forces acting on the component. In some applications, the channels enclose a liquid, and the sensors comprise pressure sensors which detect changes in pressure within the liquid due to the volumentric changes in the channels. The system also may comprise a compensation system which compensates for external influences, such as temperatures and hydrostatic pressures.

1. A system for measuring force, comprising:
a drill string disposed in a wellbore, the drill string having a downhole component and a load cell coupled with the downhole component, the load cell comprising:
a plurality of channels, each channel being filled with a liquid; anda plurality of pressure sensors, each pressure sensor being associated with a corresponding channel of the plurality of channels, the pressure sensors measuring changes in pressure resulting from changes in volume in the plurality of channels when the downhole component is subjected to a sufficient load force.
