FIELD: chemistry.
SUBSTANCE: composition of drilling water-based fluid including a continuous water-based phase; a material of reactive clays or shales; a hydration inhibitor of shales containing polyaminoamide-epichlorhydrine resin, where the hydration inhibitor of shales is present with a concentration sufficient to reduce the reactivity of clays or shales.
EFFECT: inhibition of swelling of clay and shale that come into contact with fluids used in the drilling and the construction of oil and gas wells.
