Studying rheological properties and reactivity of acid solutions with thickening additives

This article is the result of studies rheological properties and reactivity acid solutions technical lignosulfonate, decationized lignosulfonic acid, hydrochloric with addition lignosulfonate. Compositions that include lignosulfonate can be used as displacement agents in development watered layers inhomogeneous reservoir properties. The use thickening additives solves several problems. Slowing reaction rate will allow flow to leak deeper, saving capacity. height viscosity compositions increases sweep efficiency bottomhole zone by treatment. Due fact have a high concentration, selective isolation highly permeable areas realized, which, turn, contributes formation new pore channels. We evaluated interaction carbonate samples. presence an solution reduces dissolution down composition form long channels permeability,
