Popis: The object of research is underground gas storage facilities (UGS) and their technological facilities that are involved in the processes of gas injection, storage and extraction. One of the most important identified problems is the provision of reliable and economical operation of UGS in the gas transportation system (GTS) of Ukraine. One of the ways to solve the problem is development of effective software as decision-making tools, which, in the course of the studies, are not available in the dispatching services for managing the GTS. The analysis of existing programs on the market of software products shows their inconsistency with the necessary requirements for functionality, set and speed of solving problems. Basically, the developed software is oriented to the exploitation of coal-mining enterprises and could not be adapted for the operation of UGS facilities, where processes, especially filtration in reservoirs, are much faster. The development of a new multifunctional software product is aimed at providing modeling processes for gas dynamic and filtration processes in UGS facilities, identifying their technical and technological status and planning operational parameters of UGS facilities. The developed software product provides clarification of geophysical parameters of the reservoirs of the most UGS GTS reservoirs. The obtained estimates of the magnitude of the effect from the UGS reconstruction in cases of physico-chemical cuts of wells, the replacement of compressor stations of gas compressor units with imported ones with the best efficiency, in the transition from flow line-collector system of gas collection to fully flow lines. The developed software is also used for high-precision simulation of operating modes in extreme conditions of UGS operation. The systemic effect of the operation of the developed software is achieved by conducting studies to form pre-project solutions. As well as numerical experiments to study and evaluate the optimization potential, and to optimize the planning of promising solutions and operational operation.
