Nonlinear Dynamics in Drilling Engineering
Description
Over the past 70 years, an increasing number of researchers have investigated the drillstring dynamics to understand its root causes, modelling, evaluation, control, and applications. The application of drillstring dynamics can bring immeasurable economic benefits for the oil industry. Consequently, the research and investigation of drillstring dynamics is an important and interesting problem.
Understanding drillstring dynamics is not only an interesting mechanics problem, but it also has a considerable impact and benefits for the oil industry. The analytical, numerical, and experimental study of vibration and shock of the bottom hole drilling tool, such as a rotary steerable system and drillbit measurement while drilling is of particular interest. Dynamics measurement and data processing is also an essential aspect, as high-frequency measurement technology has become an important means of drilling string dynamics research in recent years.
This Special Issue welcomes research and review articles concerning both theoretical advances and potential applications for nonlinear dynamics of drillstring in oil and gas wells. Submissions are encouraged related to bifurcation and chaos in drillstring variation, vibrations forms and evaluation methods, theoretical models of slender flexible drillstring, dynamics measurement and data processing, stick-slip, vibration control, and applications of drillstring vibrations and shocks.
