Hydrogasdynamic modeling of optimization of underground gas storage development

On the basis of large-scale gas-hydrodynamic balance models, the problem of optimizing the cyclic development of underground gas storage (UGS) facilities has been formulated and solved. An algorithm has been developed that allows optimal control of the UGS development process, taking into account the limitations on the flow rates of certain wells. For its implementation, a specific model structure of the Kalmaz UGS facility was selected. It is shown that optimal regulation of the values of flow rates and depressions of wells ensures minimal flooding of well products during the extraction of total gas, the values of reception and repression of wells ensure maximum removal of the gas-water boundary from the bottom of the well during the injection of total gas.
