Abstract

In one aspect of the invention, a downhole centrifugal drilling fluid separator has a bore within a tubular body comprising a central axis. The bore is formed to receive drilling fluid comprising particulate matter. At least one fin rigidly fixed within the bore and at least one port formed in a wall of the tubular body. As the drilling fluid flows through the tubular body the at least one fin creates a rotary motion within the drilling fluid forcing a portion of the particulate matter away from the central axis and through the at least one port in the tubular body.
