Zusammenfassung:The invention relates to an emulsifier for emulsions used in well stimulation, which is based on mixtures of oils of vegetable and animal origin or residues from the distillation of fatty acids of vegetable or animal origin, consisting of a mixture of oils of vegetable and animal origin or residues from the distillation of fatty acids of vegetable or animal origin to which there can optionally be added 20...40% vegetable or naphthenic fatty acids and mono- or di-ethanol amine or a mixture thereof in a ratio of 1 : 0.7...1, the reaction product being dissolved in a ratio of 10...20% in light aromatic solvents. Invenţia se referă la un emulgator pentru emulsii folosite la stimularea sondelor, pe bază de amestecuri de uleiuri vegetale şi animale, sau reziduuri de la distilarea acizilor graşi vegetali şi animali, constituit dintr-un amestec de uleiuri vegetale şi animale, sau reziduuri de la distilarea acizilor graşi vegetali sau animali, cu un adaos opţional de 20...40% acizi graşi vegetali sau naftenici, şi mono- sau dietanolamină, sau un amestec al acestora, într-un raport de 1:0,7...1, produsul de reacţie fiind dizolvat în proporţie de 10...20% în solvenţi aromatici uşori.
