发明名称 DRILL BITS HAVING DEPTH OF CUT CONTROL FEATURES AND METHODS OF MAKING AND USING THE SAME
摘要 A drill bit for drilling a borehole in an earthen formation may include a bit body having a bit axis and a direction of rotation about the bit axis; at least two blades extending azimuthally from the bit body; and a plurality of cutting elements disposed on the at least two blades; the plurality of cutting elements forming a cutting profile in a rotated profile view, each cutting element having a radial distance from the bit axis. At least one blade, at its formation facing surface, may include, between two radially adjacent cutting elements on the at least one blade, a raised depth of cut feature for each cutting element on the other of the at least two blades that are at radial distances from the bit axis intermediate the radial distances from the bit axis of the radially adjacent cutting elements on the at least one blade.
