尾流干涉下旋转钻柱流致振动数值模拟研究
Numerical study of flow-induced vibration of the rotating drill string under wake interference
摘要
Abstract
Considering the flow field interference of the drilling fluid recovery riser on the rotating riserless drill string,the numerical simulation of the flow-induced vibration of riserless drill string coupling interference effect is carried out.The interference vibration solver for the rotating riserless drill string and drilling fluid recovery riser system is developed by the open-source program.This solver enables multi-factor coupling of shear flow,drill string rotation,and structural vibration.It aims to explore the dynamic response evolution rule of the tandem drill string-riser structure and the evolution mechanism of vortex shedding modes.Results show that the Magnus effect is significantly reduced under the coupling interference effect,and the wake asymmetry of the riserless mud-recovery system is weakened.The shielding effect suppresses the offset of the downstream drill string to the bal-ance,and the deflection and amplitude in cross-flow are suppressed when Ur≤6.4.Wake excitation occurs when 5.1≤Ur≤11.5,with increased amplitude,widened lock-in range,and lagging behind the isolated riserless drill string.The balance deflection and amplitude of the upstream riser are weakly interfered by the downstream drill string,and the downstream drill string is strongly interfered by the upstream riser.关键词
