Hard formation PDC bit technology is constantly improving

With the material level of industrial technology and PDC bit design technology, hard formation PDC bit technology is constantly improving. With the development of the oil industry, the number of exploratory wells drilling depth increases every year, drilling difficulty is gradually increased. Deep strata Drillability poor drilling cycle is long, the high cost of drilling and other issues become increasingly prominent, which the PDC bit design put  abrasive wheels  requirements. Based on how to  polycrystalline diamond  penetration rate, reduce drilling costs, reduce the number of bits used and other technical requirements of the polycrystalline diamond compact drill drilling process the finite element simulation to study the impact of the drilling process several major factors, while developing a  Diamond blade  diamond compact impact resistance, abrasive resistance and thermal stability performance testing program, and the use of residual thermal stress analysis of the main factors. By considering the PDC bit cutting angle, cutting and drilling speed on the impact of the drilling process, the use of polycrystalline diamond compact drill bits for rock drilling process was simulated, the establishment of the cutting angle changes between drilling efficiency and relationship
