Benefits of technology

The present patent provides a method, apparatus, and drilling system for determining wear on a component by measuring a change in a parameter of an oscillating member caused by a particle freed from the component during wear on the component. The technical effects of this technology include improved monitoring of drilling tool wear and reduced downtime for maintenance.

Problems solved by technology

Many oil-filled systems include moving parts that experience wear.
While the particles may clutter the system if left in the fluid, the amount of particles is related to the amount of wear that has been experienced by the moving part.

Embodiment Construction

[0016]FIG. 1 shows an exemplary drilling system 100 suitable for employing an exemplary wear measurement device 128 of the present disclosure. The exemplary drilling system 100 includes a derrick 102 and hook 104 supporting a drill string 110 disposed in a borehole 108 penetrating formation 106. The drill string 110 includes a drill bit 112 at a bottom end. Pumps 114 circulate drilling fluid through a standpipe 116 and flexible hose 118, down through an interior of the hollow drill string 110 to exit at the drill bit 112. The drilling fluid is returned to the surface via an annular space 120 between the drill string 110 and a borehole wall 122. The drill string 110 may include a bottomhole assembly 124 that may include various components 126 such as moving parts or parts that experience wear in the downhole environment of the borehole 108. The drill string 110 may further include the exemplary wear measurement device 128 within a suitable proximity of the exemplary component 126 for...

Abstract

A system, method and apparatus for determining wear on a component of a tool is disclosed. An oscillating member receives a particle freed from the component as a result of the wear on the component. A measuring device measures a change in a parameter of the oscillating member resulting from receiving the particle. A processor determines the wear on the component from the change in the parameter. In one embodiment, the component may include a component of a downhole tool.

Description

BACKGROUND OF THE DISCLOSURE[0001]1. Field of the Disclosure[0002]The present disclosure relates to determining a wear on a component and, in particular, to determining wear from an effect on an oscillating member due to particles worn from the component and accumulated at the oscillating member.[0003]2. Description of the Related Art[0004]Many oil-filled systems include moving parts that experience wear. Over the course of time, particles are worn away from a surface of the moving parts and are carried away via a fluid surrounding the moving part. While the particles may clutter the system if left in the fluid, the amount of particles is related to the amount of wear that has been experienced by the moving part. Thus, determining accumulating the particles and determine their amount may be useful in determining a wear of the system. Understanding the wear of the system enables having a suitable maintenance schedule.SUMMARY OF THE DISCLOSURE[0005]In one aspect, the present disclosur...
