FIELD: oil and gas industry.
SUBSTANCE: composition for bottomhole formation zone treatment and isolation of water influx to the well comprises the following ingredients, wt %: surfactant 1.0-10.0, silicone-containing substance 0.5-15.0, carbamide-formaldehide concentrate 0.5-10.0, carbamide 0.5-5.0 and water - the remaining part. Additionally the composition may contain wt %: corrosion inhibitor or bactericide corrosion inhibitor 1.0-5.0 and/or thickener 1.0-10.0.
EFFECT: development of multifunctional composition for bottomhole formation zone treatment and isolation of water influx to the well featured by high adhesion and strength characteristics in wide range of temperature and salt content of formation water salinity and having high hydrophobisated, anticorrosion, bactericide properties at reduced wax deposition in the bottomhole formation zone.
