Design of Diamond Bits Water Passage System and Simulation of Bottom Hole Fluid Are Applied to Seafloor Drill
Autor: Jialiang Wang, Dilei Qian, Yang Sun, Fenfei Peng
Publikováno v: Journal of Marine Science and Engineering, Vol 9, Iss 10, p 1100 (2021)
The performance of the diamond bit directly affects the drilling efficiency of the seafloor drill. The drill bits used in land drilling are prone to abnormal wear, low coring efficiency, and large sample disturbance in marine exploration. At first, i
