Abstract
A technique for forecasting the operating life of coil tubing, as opposed to the known methods can reflect a full history of inelastic deformation and accumulation of the damage by a specified object is proposed in the paper. This technique is based on laboratory and bench mechanical tests. Also, authors rely on special software modules developed in the ANSYS Mechanical package for the calculation of kinetics of inelastic deformation of a coil tubing fragment in bench tests and a section of coil tubing when a standard operating procedure is carried out.
