Secondary formation opening using cumulative perforation is a key scientific theme, addressed in a number of studies by Russian and foreign researchers. Test results are reviewed, bench studies to ensure reliability are summarized, and various process optimization methods are proposed. Taking into account the complications that can occur during field and laboratory studies and the advances of modern computing technologies applied for various technical processes, including drilling, numerical modeling is becoming increasingly relevant. The authors of the article present the results of numerical modeling of cumulative perforation of a well wall using a PKS-105 perforator, using ANSYS Fluent software based on fields test data. The static pressure data fields, flow velocity, and gas phase fraction which are in qualitative agreement with the expected system behavior during perforation were obtained. The modeling was performed taking into account actual geometric, physical, and operational parameters. The conducted modeling provides a deeper understanding of the processes occurring during secondary formation penetration and can be used to optimize perforation technologies.
