Abstract
Perforating operations increase production efficiency of oil and gas wells. Insufficient understanding of the operating mechanism and characteristics of perforators in wells may lead to perforating device failure, explosions, and accidents. It is therefore important to further explore this issue. In the present paper, the dynamic response of a perforating string is studied. A simplified static load model and perforator dynamics are investigated using ANSYS LS-DYNA software; a series of targeted modeling and simulation calculations is carried out. We develop and test a simplified perforating string model and analyze its mechanical response characteristics under various loads.
