It is known that cumulation is widely used both in military equipment and in civilian industry. To create the possibility of oil inflow from the formation, a number of channels (holes) are created in the casing and the surrounding cement ring against the oil-bearing formation, providing communication between the formation and the well: through these channels, oil enters the well. This article presents the results of testing the methodology for creating a computer model of the cumulative action of an explosion in ANSYS AUTODYN, which allows you to create a computer model of the cumulative action of an explosion in 18 main stages and to accurately calculate the penetration depth. Thus, the obtained models of the process of cumulation of a charge with different angles of the cone of the solution of the cumulative lining made it possible to determine the exact values of the penetration depths, build their dependence on the diameter of the charge of a given volume, evaluate their influence and compare the simulation results with the experimental results. A comparative study of the results of modeling and experiment has been carried out.
