FIELD: well treatment devices, particularly to stimulate oil production from wells. ^ SUBSTANCE: method involves creating the first and the second flows moving from well head to reservoir; injecting plugging fluid including plugging material suspended in carrier liquid so that the flow is in contact with well wall inside underground reservoir; separating carrier liquid from plugging material by liquid carrier supply through orifice row extending along the second flow path, wherein the orifices have dimensions, which permit carrier liquid passage and restrain plugging material as it touches the orifices; continuing plugging fluid up to necessary plugging material accumulation to create solid bridge; introducing reservoir treating fluid after solid bridge creation along the first fluid flow path and in contact with reservoir surface in well adjoining accumulated plugging material, which creates solid partition. ^ EFFECT: increased well treatment efficiency. ^ 25 cl, 11 dwg |
