A theoretical study has been performed on the buckling and lateral vibration of drillpipe interacted with incompressible fluid in vertical holes. Particular attention is paid to the flow–pipe interaction near drillpipe neutral zone. A new theoretical model has been established. The flow–pipe interaction forces are characterized in this model. Dimensional analysis has been conducted to generalize this model. An innovative numerical method has been developed to solve the eigensystem. Several numerical examples are provided to show the effects of flow–pipe interaction on drillpipe buckling and dynamics. Results show that drilling fluid has significant hydrodynamic influence on drillpipe statics and dynamics.
