The paper deals with the results of experimental studies on acid treatment of well bottom-hole zone with preliminary isolation high permeable zones via foam composition. It is defined that suggested method significantly increases oil recovery factor. As a result of field tests on developed method in two injection wells on Jhetybai field (Kazakhstan) wells’ injection capacity dramatically increased, oil flow rate raised and water cut on observation wells reduced as well.
