In order to determine the productivity of oil and gas field reserves it is necessary to assess the void-pore space of the reservoir rocks that form them. Atomic-force microscopy and acoustic emission methods were used for this purpose on samples of sandstone SiO2 reservoir rock to study its porosity coefficient. The growth of internal friction maximum height testifies the growth of the structural defects concentration n, and the broadening of internal friction maximum here represents the relaxation process of structural defects new types in sandstone SiO2 reservoir rocks. The structure of the mySQL database of geological information, physical and petrochemical properties of sandstone SiO2 reservoir rocks, special data management procedures have been developed. All results of calculations carried out by the automated system, are recorded in the database in automatic mode, which made it possible to exclude the possibility of entering incorrect data by the operator in manual mode. The measuring of internal friction background after mechanical treatments, temperature gives information about the changes of the elastic strains fields in sandstone SiO2 reservoir rock.
