Finite element analysis of drill pipe-slip system

As an important tool for tripping of a drill-string, drill-pipe (DP)-slip system directly affects both the service life DP and target depth it can reach. In this paper, finite element (FE) model programmed in ABAQUS is used to simulate interactions within DP-slip system. For model, materials, geometric dimensions, loads, boundary conditions were determined from actual A special attention has been paid on stress field slip insert focusing parameter optimization with regards distribution, wherein factors like longitudinal groove number insert, inserts, row spacing inserts are considered. Numerical results show that circumferential distribution direction axis change stresses inner surfaces higher than outer surfaces. Effects parameters distributions studied corresponding optimized values obtained, which be when designing tools.
