METHOD FOR ADJUSTING PENETRABILITY OF OIL BED Russian patent published in 2004 - IPC

Abstract RU 2241826 C1

FIELD: oil extractive industry.

SUBSTANCE: method includes pumping through force well of compound prepared when mixing at 20°C during 1-5 days of argillaceous suspension with concentrated water solution of alkali reagent and pushing by mineralized water, pumping is then performed for other compound - prepared when mixing at 50-90°C temperature during 2 days argillaceous suspension with concentrated water solution of alkali reagent, and after said compound - isolating layer of argillaceous suspension. Said pumping is performed with volumetric relation of compounds prepared at 50-90°C and 20°C respectively from 1:4 to 4:1.

EFFECT: higher efficiency.
