Изобретение относитс к нефт ной промышленности, а именно к технологии добычи, сбора и транспортировани парафинистых нефтей, в частности к способам удалени смоло-парафиновых отложений с поверхности нефтепромыслового оборудовани .The invention relates to the petroleum industry, in particular, to the technology for extracting, collecting and transporting paraffinic oils, in particular, to methods for removing tar-paraffin deposits from the surface of oilfield equipment.
Известен состав дл удалени тведых парафиновых отложений на основе ароматического бензина и фракции пийерилена 1 .A known composition for removing paraffin wax deposits based on aromatic gasoline and a pyerylene fraction 1.
Наиболее близким к предлагаемому по технической сущности и составу вл етс состав дл удалени асфальто-смолистых отложений, содержащий смесь алкилзамещенных ароматических углеводородов - бутилбензольную фракцию 2.Closest to the proposed technical essence and composition is a composition for removing asphalt-resinous deposits, containing a mixture of alkyl substituted aromatic hydrocarbons - butylbenzene fraction 2.
Однако известные составы не обеспечивают полного удалени смолопарафиновых отложений, особенно старых, содержащих до 75% акзисных смол и асфальтенов. Кроме того, скорость растворени твердых парафиновых отложений крайне низка и составл ет 6-11 ч.However, the known compounds do not completely remove resin-paraffin deposits, especially old ones, containing up to 75% of acres and asphaltenes. In addition, the dissolution rate of paraffin wax deposits is extremely low and is 6-11 hours.
Цель изобретени - повышение эффективности удалени твердых отло кений с поверхности нефтепромыслового оборудовани .The purpose of the invention is to increase the efficiency of removing solid deposits from the surface of oilfield equipment.
Поставленна цель достигаетс тем, что бутилбензольна фракци дополнительно содержит пиперилен, изоамины и изопрен при следующем соотношении компонентов, вес.%:This goal is achieved by the fact that the butylbenzene fraction additionally contains piperylene, isoamines and isoprene in the following ratio of components, wt.%:
Пиперилен 19-31 Изопрен8-12Piperylene 19-31 Isoprene8-12
Азоамины 8-12 Бутилбензольна Azoamines 8-12 butylbenzene

Бутилбензольна фракци вл етс побочным продуктом в производстве изопрена и содержит бутилбензол, полиалкилбензол, изопропилбензол. Ее плотность 0,861 г/см температура кипени 150-210°С. Она не обладает коррозионной активностью, хорошо смешиваетс с углеводородными жидкост ми .The butylbenzene fraction is a by-product in the production of isoprene and contains butylbenzene, polyalkylbenzene, isopropylbenzene. Its density is 0.861 g / cm. The boiling point is 150-210 ° С. It is non-corrosive, well mixed with hydrocarbon fluids.
Состав готов т смешением компонентов в указанном соотношении. Эффективность составов оценивают по скорости , очищени пластин от смоло-парафиновых отложений и чистого технического парафина. Результаты опытов приведены в таблице.The composition is prepared by mixing the components in the indicated ratio. The effectiveness of the compositions is assessed by the speed of cleaning the plates from resin-paraffin deposits and pure technical paraffin. The results of the experiments are given in the table.
