Influence of Perforation Explosion Load on the Tubing in Deep Water Well Testing

Abstract

The technology of TCP combined well testing is widely used in deepwater perforation and can cause string damage accidents. In order to improve the safety of the perforating string ANSYS/LS-DYNA software was used to analyze the influence of different parameters such as number of ammunition, tubing length, and the choice of perforation technology, on the tubing strength and deformation. Numerical simulation results show that the most vulnerable segment of the tubing is located at the bottom of the tube. The tubing length parameter can be effectively used to reduce the risk of tubing damage. The simulation model was verified by a field application case study.
