FIELD: oil and gas production.
SUBSTANCE: stabilizer is composed of, wt %: nitrilotrimethylphosphonic acid 2.5-20, oxyethylenediphosphonic acid 2.5-60, cationic surfactant 1.0-40, hydrophobic organosilicon liquid (oil wetting agent) 0.5-10.0, and moisture absorbent 5-50. Use of stabilizer prevents precipitation of salts in formation pores, removes capillary bound water from formation pores, removes reaction products, asphaltenes, tars, and paraffins from bottomhole zones of injection and production wells, and enhances oil wetting properties of treated surfaces.
EFFECT: increased oil recovery from production wells.
