| titleOfInvention | Method of stabilization of hydratable clay |
| abstract | FIELD: mining. n SUBSTANCE: invention relates to stabilization of the underground formation, containing hydrophilic index minerals by means of the methods including first front liquid injection, it contains first water base liquid and solution of first clay stabilization, where the first clay stabilization presents in the first water base liquid at first concentration, then injection of treating liquid containing the second water base liquid and solution of second clay stabiliser, where the second clay stabiliser presents in the second water base liquid at second concentration, where the first concentration of clay stabiliser solution is higher than second concentration of clay stabiliser solution. At that the first clay stabiliser and second clay stabiliser each independently represents at least one of the following substances: polymer, soluble organic stabilizing compound and any their combination. n EFFECT: clays stabilization against swelling and migration fine disperse rocks, that is ensured at more deeper level in underground formation upon decreasing of total concentration of stabilization components. n 16 cl, 4 dwg |
