摘要： A system (10) for drilling a borehole (14) in a subterranean formation (16) containing a fluid (18), comprising: an outer tube (24) defining an outer tube distal end (26) configured for attaching a drill bit (12) thereto and a flow controller receiving section (27) spaced apart therefrom; a flow controller (28) including a flow controller body (30) defining body proximal and distal ends (32 and 34) and securable to the outer tube (24) in the flow controller receiving section (27); and a drilling accessory (36) insertable in the outer tube (24) and through the flow controller (28). The flow controller (28) is movable between open and closed configurations. In the open configuration, the flow controller (28) allows passage of the drilling accessory (36) therethrough. In the closed configuration, the flow controller (28) hinders flow of the fluid therethrough towards the borehole proximal end (20) when the flow controller (28) is located closer to the borehole proximal end (20) than the fluid (18).

摘要： A drill bit (26), the drill bit (26) comprising: a substantially tubular bit body (30) defining a body proximal end (32) and a substantially longitudinally opposed body distal end (34); a crown (38) extending from the bit body (30) at the body distal end (34), the crown (38) having a generally annular configuration defining crown inner and outer diameters (48 and 50); the crown (38) including a plurality of segments (46) provided between the crown inner and outer diameters (48 and 50), at least one of the segments (46) extending only partially radially across the crown (38) between the crown inner and outer diameters (48 and 50).
