Study on rock breaking law of ring groove PDC bit mixed PDC cutter and field test

Year: 2025

Type: article

Abstract: Compared with single Planar PDC cutter cutting 2.5mm, the overall rock breaking efficiency of Ridged PDC cutter, Tri-ridged PDC cutter and Stinger PDC cutter cutting 0.5mm and Planar PDC cutter cutting 2mm mixed double tool in annular groove area is increased by 6.68%, 7.71% and 6.75% respectively, and the cutting stability of Planar PDC cutter is increased by 47.22%, 24.42% and 43.9% respectively; Compared with single Planar PDC cutter cutting 3mm, the total rock breaking efficiency of Ridged PDC cutter, Tri-ridged PDC cutter and Stinger PDC cutter cutting 1mm and 2mm mixed double tool in annular groove area increased by 9.52%, 4.2% and 7.79% respectively, and the cutting stability of Planar PDC cutter increased by 40.73%, 17.86% and 36.09% respectively; Comprehensive study results show that Ridged PDC cutter and Planar PDC cutter or Stinger PDC cutter and Planar PDC cutter should be selected when cutting ring groove area with double tool mixed with Non-planar PDC cutter and Planar PDC cutter; Finally, through field test, CAS 6164HC type 12.25 inch double row tool annular PDC bit was used in Yun 'an 010-X1 well. Compared with adjacent wells in the same layer, the average penetration rate increased by 26.9%, and the newness of annular bit reached 80% after drilling. The research results provide a corresponding optimum scheme for improving the rock breaking law of annular PDC bit and selecting different PDC mixed tool arrangement.
