METHOD FOR BLOCKING HIGH-PENETRABLE WATERED OIL BEDS Russian patent published in 2005 - IPC

Abstract RU 2244820 C1

FIELD: oil extractive industry.

SUBSTANCE: method includes pumping, in carrying liquid - waterless mixture of oil products containing waterless oil, of powder-like water-soluble polymer and connector in amount of 0.05-0.2% for mass of carrying liquid or 30-100% for mass of power-like water-soluble polymer, as said mixture a mixture of waterless oil and light oil products processed in relation 0.1:9.9-9.9:0.1 is used, and as connector - dry aluminum nitrate, chrome nitrate, iron nitrate, magnesium nitrate, barium nitrate, calcium nitrate or their mixtures.

EFFECT: higher efficiency.
