  • Publication number: 20120043137
    Abstract: A rotary drill bit having one or more fluid nozzles is provided. Each nozzle may include interior surfaces designed to optimize hydraulic performance and efficiency of fluid flowing through the nozzle. The interior surfaces cooperate with each other to minimize turbulent fluid flow through the respective nozzle. Each nozzle may also include a discharge port or outlet with at least one Coanda surface operable to direct fluid flow in a direction which optimizes efficiency of transferring fluid energy to adjacent portions of a wellbore. The orientation of fluid flow from each nozzle may be directed to optimize cleaning of associated cutting structures and/or to minimize or prevent balling of formation cuttings.

  • Patent number: 8020639
    Abstract: The blades of a PDC bit have a nozzle between them preferably oriented laterally across the plane of the cutters on the blade and more preferably in a trough disposed adjacent the row of cutters. The cutting is less likely to adhere to the bit surface because the trough abruptly spaces back the bit surface and the spray being oriented radially preferably into the trough gets between the bit surface and the cutting before it can adhere to the bit surface using the fluid energy to drive the cutting into the junk slot.

  • Patent number: 7984772
    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.

  • Publication number: 20100294567
    Abstract: A system for use in excavating a wellbore that includes a drill string and attached drill bit that has nozzles that are in fluid communication with the drill string. The system receives pressurized slurry of fluid and impactor particles and directs the slurry at a subterranean formation from the nozzles to form the wellbore. Discharge streams are formed from the slurry exiting the nozzles, the discharge streams impact and fracture the formation to remove material. The nozzles are oriented so that the streams excavate in the middle and periphery of the borehole bottom. The nozzles can be oriented to form frusto-conical spray patterns when the bit is rotated, wherein the spray patterns can intersect or overlap.
