Finite Element Analysis on the Concrete Damage of Cross-Formation Perforation upon ANSYS/LS-DYNA

Abstract:

Using classical explicit nonlinear dynamic analysis software of ANSYS/LS-DYNA, this paper analyzes the process of perforating jet penetrating on four types of concrete target with unconfined compressive strength of 30 MPa, 50 MPa, 30 MPa & 50 MPa and 50 MPa & 30 MPa. The result shows that penetration of shaped charge will decrease if cross-formation perforation occurs and in order to guarantee the penetration performance during perforating, perforating should be parallel to the direction of oil formation and be avoided from working on high-strength tight formation and up-and-down cap-rock.
