| titleOfInvention | Oil minefield development control method (versions) |
| abstract | FIELD: oil and gas industry. n SUBSTANCE: invention refers to development of oil minefields, and can be used when developing flooded oil formations which are non-homogenous as to permeability. Oil minefield development control method includes injection of gel-forming compound based on polysaccharide; compounds of polyvalent metal, water, and process exposure required for gel-forming. Guar gum is used as polysaccharide, zinc oxide in the presence of chrome acetate in mineralised water is used as the specified compound as per the first version, and magnesium oxide in the presence of chrome acetate both in fresh and mineralised water is used as the specified compound as per the second version, and exposure is performed within 3 to 5 days at component ratio, wt %: guar gum 0.2-0.5, zinc oxide 0.03-0.05 and chrome acetate 0.02-0.1, or magnesium oxide 0.02-0.04 and chrome acetate 0.01-0.12, and water is the rest in versions respectively. n EFFECT: improving control efficiency of development of flooded oil formations which are non-homogenous as to permeability owing to improving filtration characteristics of gel-forming compounds having selective effect, and increasing their strength and enlarging process capabilities of the method. n 2 cl, 3 tbl |
