Abstract
An earth-boring bit includes a bit body threaded at its upper extent for connection to a drill string and a plurality of blades on the bit body, each blade having a leading edge and a trailing edge. A plurality of cutting elements is arranged on the leading edge of each blade and a junk slot is defined between pairs of adjacent blades. A surface texture may be formed on the surface of the junk slot, the surface texture being selected to alter a flow of drilling fluid through the junk slot. At least one milling element may extend at least partially across the junk slot between the trailing edge and leading edge of adjacent blades, wherein flow of cuttings generated by the cutting elements is impeded until the cuttings are disintegrated to a selected size.
IPC Classes ?
- E21B 10/60 - Drill bits characterised by conduits or nozzles for drilling fluids
- E21B 10/61 - Drill bits characterised by conduits or nozzles for drilling fluids characterised by nozzle structure
- E21B 10/43 - Rotary drag type drill bits with teeth, blades or like cutting elements, e.g. fork-type bits, fish tail bits characterised by the arrangement of teeth or other cutting elements
- E21B 10/42 - Rotary drag type drill bits with teeth, blades or like cutting elements, e.g. fork-type bits, fish tail bits
