Annotation:

The article, using modern information technologies (ANSYS AUTODYN application software), presents the developed methodology for creating a computer model for accurate determination of the penetrating action of the perforator cumulative charge made of a high-power mixed energy-saturated material with a segmented lining according to the penetration depth in a steel barrier, used during perforation-explosive works in oil wells. A virtual experiment was carried out with a model of a perforator cumulative charge to study the explosion directional effect. With the help of computational experiments, the influence of the lining deflection on the penetration depth was established. The optimal deflection of the segmental lining of the perforator cumulative charge was determined to be 0,44 to ensure the maximum penetration depth. A comparative study of the results of computer simulation and full-scale experiment of cumulative charges penetrating ability is presented.
