The purpose of the work is to develop mathematical models, software tools, theoretical and methodological foundations for technical and organizational systems of the oil and gas complex and their effects on the environment. Research methods – methods of mathematical modeling, using the theory of ordinary differential equations, equations of mathematical physics, theoretical mechanics and numerical methods of implementing process models that take place in the oil and gas industry and ecology. The most important scientific or scientific and technical results were obtained. - the value of the change in pipeline throughput when the cross-section configuration is changed (appearance of ellipticity) is estimated; - calculated dependences were established to assess the change in the range of distribution of harmful substances depending on the selected parameters; - a mathematical two-dimensional model of the movement of solid bodies and the action of the technological load in mechanical systems with a chain-branched method of connecting masses is proposed to describe the dynamic mode of operation of all types of vibrating aggregates with a chain-branched method of connecting solid bodies; - the methods of researching energy dissipation in mechanical multi-section systems with a chain-branched method of connecting solid bodies have been improved; - the approach to modeling the process of the dynamic mode of operation of the vibro-impact grid has been improved; - improved theoretical approaches for assessing the accuracy of solving the problem of modeling the working processes of a vibro-impact unit with a chain-branched method of connecting solid bodies and checking the adequacy of models based on the analysis of the a Product Description popup.authors Vavryk Tetiana O.
