METHOD OF OIL FIELD DEVELOPMENT Russian patent published in 2012 - IPC E21B43/22

Abstract RU 2439301 C1

FIELD: gas and oil production.

SUBSTANCE: method involves loading of working medium under pressure through injection wells and oil extraction through production wells. First, sodium silicate solution in water at 1:2 - 1:5 respective ratio with 0.04-0.06% polyacrylamide added in the volume of 5-30 m³ is pumped into at least one injection well. Then 1-5 m³ of spacer fluid is pumped in sequence. Further, 5-30 m³ of 5% aqueous solution of calcium chloride is pumped with 0.003-0.007 vol.% salt deposition inhibitor "INSAN" added.

EFFECT: enhanced development efficiency by increased field coverage due to available power resource during field flooding.
