FIELD: oil-and-gas industry.
SUBSTANCE: invention related to creation of a well process fluid with controlled absorption in thermo-baric conditions of an oil, oil-gas, or gas reservoir, which can be used for wells boring, killing or washing. The process fluid with controlled absorption in thermo-baric reservoir condition contains in 1 m3 of the well process fluid, kg: xantan 3-20, polyanionic cellulose 3-20, water or a water-salt solution is the rest. Invention develops in formula subclaime.
EFFECT: process fluid with controlled absorption in thermo-baric reservoir condition efficiency increase due to providing reversible fluid treatment character.
