Изобретение относитс к нефт ной промышленности и может быть использовано дл удалени смолисто-асфальте- новых и парафинистых отложений, например из призабойной зоны скважин, с поверхности подземнотчз и надземного промыслового оборудовани , в системах добычи , транспорта и хранени нефти.The invention relates to the petroleum industry and can be used to remove tar-asphaltene and paraffin deposits, for example, from the well bottom zone, from the surface of underground fire and surface equipment, in oil production, transportation and storage systems.
Известен реагент дл удалени смолисто-асфальте новых и парафинистых отложений , состо щий из 65% керосина и 35% ацетона fl .A reagent for removing tar-asphalt and paraffin deposits, consisting of 65% kerosene and 35% acetone fl, is known.
Недостатком известного состава SJB- л етс то, что он не обеспечивает высо кую эффективность удалени смолистоасфальтеновых и парафинистых отложе НИИ. Кроме этого, данный состав летуч и взрывоопасенThe disadvantage of the known composition SJB-l is that it does not provide a high removal efficiency of resin-asphaltene and paraffin deposits. In addition, this composition is volatile and explosive.
Цель предлагаемого изобретени «повышение степени удалени смс нсто- асфальтеновых и парафинкстых отложений .The purpose of the present invention is an "increase in the degree of sms removal from bostophaltic and paraffin deposits.
Поставленна цель достигаетс тем, что в качестве реагента дл удалени The goal is achieved by the fact that, as a reagent for the removal of
смолисто- сфальтеновых и парафинистых отложений используют тетралкилметилен- бис-амин, имеющий следующую структурную формулуresin-spaltene and paraffin deposits use tetralkylmethylene-bis-amine, having the following structural formula
