Abstract
A stabilizer, drill bit, or other component of a bottom hole assembly for use in drilling a borehole includes an elongate and generally cylindrical body, a flow bore in the body, a plurality of outwardly-extending blades, with a valley disposed between adjacent blades. A ring segment that is spaced from the body and extends across at least one valley to define a flow passage through which cuttings-laden drilling mud is conveyed with an upwardly-direct trajectory. The body includes a hole or passageway for conveying drilling mud from the flow bore to between the blades. The passageway terminates in an exit directed toward the flow passage so as to provide fresh drilling mud with a trajectory such that the fluid passes through the flow passage.
