AI Technical Summary
During the drilling process, as the distance between the drill bit and the ground increases, the drilling fluid delivery pressure cannot be kept constant, resulting in the accumulation of cuttings and impurities in the drill bit flow channel and cutting area, which affects drilling efficiency.
A PDC drill bit with a dual-channel structure was designed. By incorporating components such as isolation components, flow guiding and pressure stabilizing columns, elastic fluid reservoirs, and one-way valves within the drill bit body, stable delivery of drilling fluid and effective removal of impurities are achieved, preventing accumulation.
It improves drilling efficiency, ensures that drilling fluid is discharged at a stable pressure, prevents impurity accumulation, and enhances the rock-breaking efficiency and cuttings removal effect of the drill bit.
