Method of controlling formation permeability |
| abstract |
FIELD: oil and gas production. SUBSTANCE: composition for controlling permeability of formation and insulating water inflows contains 95.0-99.0% of alkaline caprolactam production waste or its mixture with industrial sweet water wherein waste represents at least 5.0%, and 0.01-5.0% of water-soluble polymer, said waste being alkaline caprolactam production drainage or alkaline adipic plasticizer. EFFECT: increased oil recovery of nonuniform oil formations. 7 tbl, 3 ex |
