Abstract

OIL WELL PERFORATORs (OWP) are explosive devices that are used in drilling industries of oil and gas wells to access the reservoir and increase the wells efficiency. The performance of OIL WELL PERFORATORs is measured by the depth of penetration that can be achieved, for this reason depth as the main parameter must be examined. In this article, a complete report of numerical simulation and performance optimization of these devices, which are indeed small size SHAPED CHARGEs, is presented. To do this, the multi-material Eulerian and the Lagrangian methods are used for simulation of the jet formation and its penetration into underground rock processes, respectively. For solving the problem of large deformation elements in Lagrangian method, erosion criterion elements were used. Because the results of jet formation and penetration process are heavily influenced by the density of the mesh, in this study mesh sensitivity was examined. The described simulation is validated by the use of reliable results of some references and then, a new charge geometry is suggested which resolves the inhomogeneities in the distribution velocity of the tail and increases the effective length of jet in the penetration process.
