Short summary
In the field of oil & gas drilling engineering, the Rotary Steerable System (RSS) is very widely used in directional drilling, the whole drillstring is rotated from the surface by a hydraulically driven top drive. In this paper we analysis of the dynamic model of the Rotary Steerable System (RSS) with a single stabilizer and flex-sub and takes a method of the longitudinal and transverse bending continuous beam method to analyse the stress of RSS with the flex-sub.
