Design character:

■Back redressings at the base of gauge avoid difficult of pulling PDC bits our of hole in unconsolidated formation, and trim wall of well.

■Adopting CFD emulational technology to calculate to optimize PDC bit, then reduce possibility of heavy breaking and wearing of bit.

■Special design of back-rake angles will decrease torque on bit, increase bit aggressiveness, improve efficiency of ROP.

■the hydrofoil shape of the gauge channels hydralic fluid and cutting to the annulus. This streamlined flow deters bailing initiation caused by vortices and eddies.
