It is noted that at a choice of the technology of wells acid stimulation in carbonate reservoir it is necessary to be guided by an integrated approach to the reagents and design. It is shown that taking into account the properties of acidic compounds for specific geological and physical conditions increases the efficiency of the well bottom zone stimulation due to a larger radius of influence, preventing the formation of insoluble compounds, bridging the pore space of this zone. The results of determining the kinetic parameters, characterizing the rate of acid composition reaction with oil- and water-saturated rock samples, are given.
