Abstract
The invention relates to oil-and-gas producing industry, in particular to methods for well treatment to increase productivity of those. Method for acid treatment of field includes pumping in of two neutral reagents with obtaining acid as result of interaction of those at well bottom zone. Pumping in is performed separately just to porous medium of bottom zone through disconnection with packer of inter-pipe space in interval of affecting with reagents. To over-packer space one pumps in reagent with density higher that density of reagent pumped in to under-packer space.
