FIELD: mining industry.
SUBSTANCE: invention relates to a well treatment fluid for increasing recovery of hydrocarbons from the formation and methods for use thereof. Well treatment fluid comprising a zirconium acetylacetonate crosslinker, dissolved in a solvent - benzyl alcohol, and a hydratable polymer, capable of forming a gel in the presence of zirconium acetylacetonate. Method of intensifying a subterranean formation, through which a well passes, including injection of said fluid into the well. Method for intensifying a subterranean formation through which a well passes, comprises injection into the well of a well treatment fluid, including zirconium acetylacetonate, dissolved in a mixture of benzyl alcohol and 2,2-dimethyl-1,3-dioxolan-4 (yl) methanol, and a hydratable polymer, capable of forming a gel in the presence of a zirconium acetylacetonate crosslinker, and slow down of the cross-linking of the well treatment fluid while the temperature inside the well is at least 100°F. Invention is developed in dependent items of the formula.
EFFECT: technical result is the increase in processing efficiency.
