“…The resulting motion trajectories and animations for points (1), (2), and (3) under different WOB conditions are presented in Figures 4 and 5. It is worth noting that for the purpose of comparing and analyzing the movement trajectory of the drillstring (1) under different conditions, the initial static state inner diameter of the riser is utilized as a reference for sizing the circle in the displacement diagram of drillstring (1). In practical drilling operations, it is typically observed that the displacement at the middle section of the drillstring below the mud line is most significant.…”

“…Deep-water drilling risers will have a significant impact on drillstring vibration [1,2], which is a crucial factor affecting drilling efficiency. The high levels of shock and vibration experienced during deep water drilling in Brazil [3][4][5] and Mexico [6][7][8] have severely affected the rate of penetration (ROP).…”

“…Numerous studies have been conducted on the vibration frequency, stress state, and fatigue risk of risers. Blevins et al and Major et al, for instance, investigated the impact of drillstring on the natural frequency and vibration of risers through laboratory tests and simulations [1,10]. Furnes et al, in addition to employing test and model analysis methods, examined field data by collecting acceleration and displacement data at a depth of 1300 m. They analyzed several potential modal modes of riser oscillation induced by seawater flow [11].…”

The swing of the riser in deep-water drilling can significantly impact the drill string. In this study, we establish a riser model that considers the combined disturbance of periodic dynamic wind and wave loads. By coupling it with the drill string model, we develop a dynamic model for deep-water drilling systems. Through analyzing multiple sets of different drilling parameters, we examine displacements and impact forces at various positions along the drill string system. Specifically, our focus lies on velocity, acceleration, and rotational speed information of BHA. We investigate how WOB and rotational speed influence motion trajectory and vibration characteristics of the drill string within the dynamic model of deep-water drilling systems. Simulation results reveal slight differences in whirling trajectories between inside the riser and below mud line for the drill string. Rotational speed has a greater impact on the drill string compared to WOB; higher rotational speeds lead to increased collision forces between the drill string system and both riser and wellbore. Our findings identify specific combinations of WOB and rotational speed parameters that can stabilize drilling operations within dynamic models for deep-water drilling systems. These research results provide valuable insights for adjusting WOB and rotational speed parameters in deep-water drilling.

“…It was concluded the PIP guide spring model can be used for riser design in lieu of the PIP guide surface model. Blevins [29] conducted laboratory tests for a riser with drilling-induced vibrations, which revealed that fluid dynamic coupling can cause vibration of a riser with a rotating drill pipe and a water-filled annulus.…”

“…The rod string dynamics in petroleum engineering had been studied extensively by many experts and scholars: the longitudinal vibration of sucker rod [13,14], the transverse vibration of traditional pressure bar [15,16] and moving beam [17,18], the transverse forced vibration of riser under tension [19][20][21], the transverse vibration and collision problems for wellbore under fluctuating pressure [22][23][24][25]. However, the research on the transverse vibration triggered by the buckling deformation excitation seems to have not been discovered so far.…”

Considering the limitations of the static buckling theory on the eccentric wear of sucker rod and tubing, a new dynamic analysis method for the transverse vibration of sucker rod in the tubing is proposed. Taking the axial distribution load at the rod body and the dynamic load at the bottom into account, the dynamic model of transverse vibration is established based on the space buckling configuration of rod string which regarded as the deformation excitation during the down stroke. To solve the mathematical equations, the finite difference method is used to discretize the well depth, and the Newmark-beta method is used to discretize the time. Meanwhile, a restitution coefficient is introduced to depict the change of velocity and the momentum after the collision. The result shows the phenomenon of rod-tubing collision occurs mainly in the down stroke after the rod string post buckling; the collision force from the wellhead to the bottom increases gradually, of which distributed almost along the entire well depth; and the high frequency collision occurs below the neutral point where the collision force is also the biggest. Further, the collision frequency and the collision force decrease successively from the neutral point to the wellhead direction. But during the up stroke, few collisions occur, and the collision force is also very small. The simulation model is suitable for the eccentric wear analysis of rod-tubing, and provides a new theoretical basis for the optimal allocation of the centralizer.
