FIELD: operation of hydrocarbon-containing beds or force wells, in particular, reduction of liquid absorption for processing of wells.
SUBSTANCE: liquid for reducing absorption of drill mud, for preventing absorption of drill mud contains: water salt solution with density of at least 1318 kg/m3; and viscous-elastic surfactant, added in efficient amount for increased viscosity under conditions of oil or gas pool close to static conditions. Methods for preventing absorption of drill mud in a well, for stopping a well, for preliminary processing of a well, for packing a well, for packing limiting sand screens all include usage of aforementioned liquid. Invention is developed in dependent articles.
EFFECT: reduction of liquid absorption under high temperature conditions.
