MODELING AND EXPERIMENTAL INVESTIGATION OF THE EFFECT OF MECHANICAL STRESSES AND DAMAGE OF METAL OF OIL AND GAS EQUIPMENT ON THE PARAMETERS OF ELECTROMAGNETIC-ACOUSTIC CONVERSION

Abstract

During operation, oil and gas equipment has a wide range of influences, under the influence of which damage accumulates, which transforms into microcracks. Develops the development of microcracks over time can become the destruction of equipment. As established by numerous studies, defects in the structure of the metal originate and develop in the areas of concentration of mechanical inclusions. To prevent the occurrence of emergencies arising from the destruction of equipment, it is necessary to identify zones of increased mechanical detection of diseases and in pathological zones of change control in exceptional cases to detect defects at the very stage of their development. Currently, in the zone of probable concentrations, mechanical quantities are calculated by calculation, and in this case, metal is monitored by non-destructive methods. A very urgent problem in the field of industrial safety of hazardous industries is the creation of detection methods and means for detecting damage to the metal structure in a sharply deformed state. A promising direction for solving this problem is the development of high-performance methods for non-destructive testing of equipment and diagnostics of hazardous production facilities based on the collection of the electromagnetic-acoustic effect (EMA), which make it possible to control the sharply deformed state of equipment and detect metal damage at the structure level. But the current emergence of non-destructive and diagnostic reports based on the EMA effect does not matter for solving problems with sensitivity and informative control. The purpose of this article is to develop an information-measuring complex for studying changes in the acoustic and electrophysical properties of metals in changing their sharply deformed state and damage to the structure. Based on the application of the application of measurement analysis for acoustic and electrophysical studies of the properties of metals and an information-measuring complex. The research results are used to study methods for detecting and processing information intended for EMA parameters, to search for the sensitivity and information content of non-destructive testing and diagnostic tools.
