Abstract
As system for measuring drilling fluid properties includes a capillary rheometer that is adapted to measure viscosity parameters of drilling fluid. The capillary rheometer includes a feed chamber, the feed chamber having a cavity, at least a first drain port for draining fluid out of the cavity, a double wall defining an annulus that opens to the cavity, and a feed port in an outer portion of the double wall that is in fluid communication with the annulus. The capillary rheometer also includes at least a first capillary tube coupled to at least the first drain port. Additionally, the disclosed system further includes a pump that is adapted to pump fluid to the feed port.
