Abstract

Состав для предупреждения образования органических отложений и гидратов в скважинах и трубопроводах, включающий депрессор, ПАВ и растворитель, отличающийся тем, что в качестве депрессора используют модифицированный разветвленный поликарбоксилат, в качестве ПАВ - низкомолекулярный неионогенный ПАВ, а в качестве растворителя - газовый конденсат, при следующем соотношении компонентов, мас.%: разветвленный поликарбоксилат 10-15, низкомолекулярный неионогенный ПАВ 10-60, газовый конденсат - остальное. Composition for preventing the formation of organic deposits and hydrates in wells and pipelines, including a depressant, a surfactant and a solvent, characterized in that a modified branched polycarboxylate is used as a depressant, a low molecular weight non-ionic surfactant is used as a surfactant, and gas condensate is used as a solvent, in the following the ratio of components, wt.%: branched polycarboxylate 10-15, low molecular weight nonionic surfactant 10-60, gas condensate - the rest.
