摘要

An integrated drill string-reamer dynamics model incorporating full-wellbore mechanics was established to characterize Reaming While Drilling vibration mechanisms. The model integrates multi-body dynamics software for constructing reamer geometric configurations and cutter mechanical interactions, with validation through field drilling datasets. Vibration Pattern Analysis of Reamers: optimized drilling parameters achieve 34–52% vibration suppression; stabilizer outside diameter enlargement within engineered parameters achieves 34–52% vibration attenuation; enhanced bit-reamer structural rigidity achieves 39.7% vibration suppression (45% stiffness elevation); Recommend a novel drill string assembly, which demonstrated remarkable vibration suppression performance in offset well field tests. The findings provide critical insights into vibration dynamics mitigation during reaming-while-drilling operations.
