FIELD: oil and gas production.
SUBSTANCE: procedure for increased rate of recovery of characteristics after shear load of fluids consists in pumping said fluid into well. Fluid is prepared with application of fluid systems with VES by addition of effective amount of amplifier composition of rheological characteristics containing poly-ethylene-glycol-poly-propylene-glycol block-copolymer and poly-naphthalene-sulphonate. Fluid for oil field treatment contains VES, the above said amplifier and a liquid carrier. The invention is developed in dependent points of formula.
EFFECT: application of VES at lower concentrations in certain versions of application at certain oil field operations - for hydraulic fracturing and gravel tightening.
