Engineering Calculation and Application of Perforation Impact Dynamic Loads in Oil and Gas well

Abstract:

The perforation impact dynamic loads can destroy or disable the tubing strings. The perforated completion process was simplified to explosion of ordinary explosive charge in perforation liquid. The dimensionless expression of perforation impact dynamic loads was derived based on main influence factors and then its engineering calculation formula was set up. A well perforation operation in western Sichuan as an example, the oil tubing strings security was analyzed by the perforation impact dynamic loads from the engineering computation formula. The results show that the tubing strings only occur elastic spiral bucking and do not occur plastic deformation which are in line with perforation operation results on site.
