Metodika ověření dlouhodobého provozu PZP na mechanické vlastnosti zásobníkové formace

Abstract

The thesis is focused on observing the behaviour of the reservoir influenced by operation of underground gas storage facility. The first part provides a basic information about natural gas. The importace of gas storage facilities, its types, related parameters and working modes, as well as an overview of the UGS in the Czech Republic are presented. In more detail the thesis is devoted to UGS Dolní Bojanovice, whose formations are subject to investigation. The thesis also deals with cycling loading operation of UGS, the reservoir pressure including its possible changes and geomechanical response to operation. It also includes description of parameters like porosity and permeability, on which the changes in the influenced rock samples from UGS Dolní Bojanovice are studed. The methodology of this research is presented and based on that the individual rock samples are evaluated.
