【 摘 要 】

Perforation is of great importance to improve the oil and gas wells productivity. This research is to simulate the process of perforating based on the structural characteristics of shaped charge jet and the penetration mechanism. The perforating process is analysed with the Arbitrary Lagrange Euler (ALE) method, including the shaped charge initiation, jet formation, and the nonlinear large deformation. In this paper, the jet shape, pressure and velocity are given, the mechanical behaviour of jet penetrating the casing, cement and rock are described in detail. The simulation model and method used in this research are proved to be reasonable and feasible. The result provides a guidance for the real-time research of perforating process.
