Annotation:

The work is devoted to the study of the influence of natural and technological parameters on the performance indicators of the processes of creation and operation of underground gas storage facilities (UGS), the gas-saturated part of which is confined to fractured-porous formations [1] with low permeability, which can be useful in the design of underground storage facilities in the specified geological structures. Hydrodynamic modeling was used as a research tool. The porosity and permeability of the matrix were considered as natural parameters, and the ratio between vertical and horizontal wells, their placement on the structure were considered as technological parameters. The main motivation for carrying out the research, the results of which are presented below, is the need to expand the network of UGS, which forces us to pay attention to geological structures with less attractive filtration and capacity properties compared to classical underground storages [2]. In particular, fractured-porous reservoir layers with low permeability belong to such structures. It is these formations that are the objects of study in this work.
