Structure design on a new type of coupled impactor
Journal of Physics: Conference Series(2024)
摘要
Abstract Improving drilling efficiency and reducing drilling cost are new challenges for deep drilling. Based on this, a coupling impactor is designed by applying the principle of hydraulic pulse pressurization and axial impact. Based on the impactor compression structure and principle, the fluid flow equation of the drilling fluid flowing through the compression mechanism and the mechanical balance equation of the piston body are established in order to study the pressure pulsation characteristics of the coupled impactor fluid.
