PDC drill bits tend to drill faster with low WOB and high RPM. They are also found to require higher torque than roller cone bits. The general recommendation is that the highest RPM that can be achieved should be used. Although the torque is reasonably constant in shale sections, the bit will tend to dig in and torque up in sandy sections.

In this paper, the cutting rock-breaking behavior of PDC bit is discussed. Rock cutting is the movement of cutter along the rock surface at a certain cutting depth, and its movement is parallel to the rock surface (Detournay et al., 2008; Jing, 2003; Yang et al., 2018). Rock is a complex porous and multi-mineral composite material which ...

manufactures 3, 5, and 6 blade steel body pdc drill bits for Shallow Oil & Gas Drilling. Cost of Matrix Vs. Steel. Drilling a well involves cost - a major factor - and matrix costs more than steel. In addition, the extra pdc cutters add to the overall costs of the pdc drill bit. These two factors make matrix bodies more expensive ...
A polycrystalline diamond compact (PDC) bit is a fixed cutting-structure bit without portable parts. Flexible design, relatively simple production process, and high economic benefits when drilling in soft to medium-hard formations increase the yearly demand for PDC bits. However, when PDC bits are drilled into formations with intense …
Hydraulic flows also cool bit cutting elements and prevent thermal damage to them. Cutter life influences bit life and the economic efficiency of a bit investment. Fig. 1 describes the nomenclature of various PDC bit profiles. Starting at the centerline of the bit and moving outward to the gauge, profile is broken into five zones: Cone; Nose ...
By virtue of the shear-cutting mechanism of the PDC bit, its drilling speed is several times faster than that of the roller cone bit. Nowadays, The PDC bit is the main rock-breaking tool in the field of oil and gas drilling (Shi et al., 2020). It is estimated that PDC bits have drilled more than 90% of the world's drilling footage, accounting ...
Taking Φ94 mm tri-wing arc-shaped PDC bit as an example, theoretical calculation results show that, with the increase of radial distance, the cutting area, cutting arc length and cutting force of ...
