FIELD: oil extractive industry, in particular, technology for increasing oil recovery of formations and productiveness of wells.
SUBSTANCE: in accordance to method for increasing oil recovery of formations, chemical reagents are forced into formation for increasing oil recovery of product wells and increased efficiency of displacement through a system of force wells, namely, calculated volume of 12% water solution of sodium hydroxide, which is then left for capillary saturation, and then calculated volume of tall oil is fed in and after 24 hours completion of product wells is started together with forcing of water into force wells.
EFFECT: increased oil recovery of beds in presence of force wells effect on face-adjacent formation zone, increased oil conductance of face-adjacent zones and productiveness of product wells.
