FIELD: oil producing industry. SUBSTANCE: well is separated above zone of treated layer and zone is filled with solution for treatment of bottomhole formation zone. Solution is let stand. Then, zone of treated layer by pumping fluid to zone above point of separation and through casing-borehole annulus towards wellhead. Pressure is rebuilt in zone of treated layer. Operation is repeated up to appearance of oil inflow. Prior to pressure rebuilding, injected additionally into well is solution for treatment of bottom hole formation zone in volume ensuring filling of zone above point of well separation. Washing of zone of treated layer is combined with oil production. EFFECT: higher efficiency.
