FRICTION APPARATUS AND METHOD FOR MEASURING LUBRICITY OF DOWNHOLE FLUIDS

摘要

A lubricity testing apparatus may have a first surface configured for moving against a second surface, a second surface, a measurement device in communication with the first surface, and an actuator in communication with the first surface. A fluid may be circulated about or over at least one of the surfaces. The measurement device may measure at least one force encountered when the first surface moves against the second surface. The actuator may move the first surface against the second surface. At least one force related to the first surface may be measured as the first surface moves against the second surface to determine the lubricity of the fluid.

1. A lubricity testing apparatus comprising:
a first surface configured for moving against a second surface, wherein the first surface is a real or simulated surface selected from the group consisting of a coiled tubing surface, a wellbore casing surface, a drill string surface, a pipe surface, a drill bit surface, a well open hole surface, and combinations thereof; a second surface different from the first surface; a measurement device in communication with the first surface for measuring at least one force encountered when the first surface moves against the second surface; and an actuator in communication with the first surface for moving one of the surfaces against the other surface.
