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.
Keywords: coil tubing; coil tubing unit; operating life forecasting; cyclic strength and plasticity characteristics; damage accumulation; laboratory and bench tests; calculation of kinetics of inelastic deformation and damage accumulation of tubular model and coil tubing in the system of ANSYS Mechanical.
