FIELD: mining; chemistry.
SUBSTANCE: invention relates to the oil industry, in particular to compositions for decolmatation of the bottomhole formation zone in terrigenous reservoirs. Composition for decolmatation of bottomhole formation zone in terrigenous reservoirs contains, wt.%: nonionic surfactant neonol “АФ” 9-6 0.3-0.4; stabilizing agent – guar polysaccharide 0.4-1.0; water – balance.
EFFECT: high efficiency of decolmatation composition due to high stability over time, improving process parameters of colmatage removal in the formation and increasing permeability of bottomhole zone of the well, which helps to reduce costs for treatment of bottomhole formation zone and increase well productivity.
