Key words: bottomhole formation zone, carbonate reservoir, acid composition, reaction retarders, permeability.

In the laboratory, on the real core samples , a comparative tests of acid solutions are performed. Tests were carried out on carbonate cores of gas and oil deposits at various reservoir temperatures.

It is confirmed that there is an optimum injection rate of acid composition, allowing the dominant form a highly conductive solution channel with a minimum amount of acid composition.
