Abstract

Ингибитор для предотвращения образования асфальтосмолистых и парафиновых отложений в нефтепромысловом оборудовании на основе оксиалкилированной алкилфеноламиноформальдегидной смолы, отличающийся тем, что, с целью повышения ингибирующих свойств для нефтей с содержанием парафина, смол и асфальтенов в соотношении 8 - 76 : 6 - 23 : 1, ингибитор дополнительно содержит сополимер этилена с винилацетатом с содержанием звеньев винилацетата 35 - 38 мас.% при следующем соотношении компонентов, мас.%:Сополимер этилена с винилацетатом - 30 - 70Оксиалкилированная алкилфеноламиноформальдегидная смола - ОстальноеInhibitor to prevent the formation of asphalt-resin and paraffin deposits in oilfield equipment based on oxyalkylated alkylphenolamine formaldehyde resin, characterized in that, in order to increase the inhibitory properties for oils containing paraffin, tar and asphaltenes in a ratio of 8 - 76: 6 - 23: 1, the inhibitor additionally contains a copolymer of ethylene with vinyl acetate with a content of vinyl acetate units of 35–38 wt.% in the following ratio of components, wt.%: A copolymer of ethylene with vinyl acetate — 30 to 70 Oxyalkylation. alkylphenolamine formaldehyde resin - the rest
