Использование: в области нефтегазодобычи. Для придания составу значений статического напряжения сдвига и способности к декольматации призабойной зоны пласта от окислов железа с одновременным предупреждением их осаждения из состава, повышения вязкости состава, снижения его фильтрации состав содержит лигносульфонаты технические (ЛСТ) плотностью 1200 кг/м3, раствор соляной кислоты 20 - 24%-ной концентрации и минерализованную воду при следующем соотношении ингредиентов, об. %: ЛСТ 35-45; указанный раствор соляной кислоты 3 - 4; минерализованная вода - остальное.Use: in the field of oil and gas production. To give the composition the values of static shear stress and the ability to decolmate the bottomhole formation zone from iron oxides while simultaneously preventing their deposition from the composition, increasing the viscosity of the composition, reducing its filtration, the composition contains lignosulfonates technical (LST) with a density of 1200 kg / m 3 , hydrochloric acid 20 - 24% concentration and saline water in the following ratio of ingredients, about. %: LST 35-45; the specified hydrochloric acid solution 3 - 4; mineralized water - the rest.
