摘要：

Interaction of carbon dioxide (CO2) on the reservoir rock is a very important element in sequestration planning. Therefore, in order to assess the impact of CO2 on the reservoir rock, a specialized test stand was designed and manufactured. It allowed the submission of actual samples of reservoir rock under the influence of CO2 in dynamic conditions. Experiments were done for two sandstone and one dolomite. For each sample (both before and after the experiment) were performed tests of the basic petrophysical parameters, mineralogical composition and x-ray microtomography. Finally a comparative analysis of the results was carried out, thereby the effect of the impact of acid gases on the studied rocks was specified.
