Highlights The coupling model of riser string and drill string is established by using Euler-Bernoulli beam model. The dynamic characteristics of drill string are compared with those under the condition of fixed riser string. The kinematic characteristics of drill string in "pipe in pipe" structure were obtained.
Abstract The deepwater drilling string system consists of riser and drill string, forming a "pipe in pipe" structure with the riser as the outer pipe and the drill string as the inner pipe, thereby increasing the complexity of simulation and analyzing the dynamic characteristics of the string system. In this paper, a coupling model of the riser string and drill string is established by using Euler-Bernoulli beam model. Based on obtaining the dynamics of drill string, considering the influence of riser vibration, the dynamic characteristics of drill string are compared with those under the condition of fixed riser string. The kinematic characteristics of drill string in the "pipe in pipe" structure are analyzed as well. The distribution of contact forces between the drill string and the inner wall of riser is also studied. The results indicate that the vibration of the riser string has a significant influence on the dynamic characteristics of the inner drill string, and there is a high risk of failure due to serious contact wear between the riser and the drill string near the underwater wellhead. This observation is consistent with practical observations.
