Dynamic Modeling and Operational Parameter Optimization of a Bidirectional Eccentric Reaming Tool in the While-Drilling Reaming Process
Eccentric reaming tools are widely integrated into bottom-hole assemblies during while-drilling reaming operations to improve borehole quality and enhance drilling-assembly passability. However, their eccentric geometry introduces periodic tool–borehole contact, friction, and impact excitations, which may adversely aff...
