Rock drilling parameters and contact mode of diamond composite bit
The rock drilling parameters and contact mode of diamond composite bit are analyzed from the following two aspects
Without considering the stress of the rock at the hole bottom, the following assumptions are made for the rock at the hole bottom:
① The rock is homogeneous and isotropic material, and there are no cracks and pores in the rock;
2. The influence of formation temperature and pore fluid on rock stress is not considered;
③ The area around the rock model and the rock bottom are far away from the hole wall.
The above two points are the analysis of rock drilling parameters and contact mode of diamond composite bit.
Focus on hot spots
