FIELD: oil industry, in particular, isolation of wells from influx water and regulation of oil deposit working process.
SUBSTANCE: face zone processing compound includes, wt%: oil-soluble surfactant 1.0-15.0; silicone or soluble or colloid sodium silicate 0.5-18.0; Polysil 0.1-2.0; water the balance. Compound may further contain calcium chloride in an amount of 1.0-10.0 wt% and hydrocarbon solvent in an amount of 2.0-15.0 wt%. Compound possesses increased structural viscosity and thermal stability, improved adhesion to rock to provide for reduced permeability of heavily flooded intercalation and increased hydrophobicity of rock surface. Specific hydrocarbon phase permeability of formation is increased as compared to water permeability owing to high oil displacing properties of compound.
EFFECT: increased structural viscosity and thermal stability of compound, regulated wettability and improved adhesion to rock and, accordingly, reduced permeability of heavily flooded intercalation.
