FIELD: oil and gas producing industry; applicable in increase of operating well productivity. SUBSTANCE: method includes injection into formation of acid solution in several cycles; step increase of bottom hole pressure to its maximum possible value with its subsequent sharp drop in each cycle of solution injection with variation of pressure gradient in each cycle in absolute value and direction. Number of cycles is at least, three. EFFECT: increased efficiency of hydrochloric acid solution treatment due to fuller realization of acid chemical activity under formation conditions. 2 cl, 1 dwg, 1 tbl |
