Description
Известны гидрофобные кислотные эмульсии дл обработки призабойной зоны карбонатного пласта в глубоких скважинах, полученные на основе нефти и стабилизированные эмульгаторами. Существенным недостатком известных эмульсий вл етс неопределенный период их стабильности, что вли ет на эффективность обработки призабойной зоны.Hydrophobic acid emulsions are known for treating the bottomhole zone of a carbonate formation in deep wells, obtained on the basis of oil and stabilized by emulsifiers. A significant disadvantage of the known emulsions is the indefinite period of their stability, which affects the efficiency of the bottomhole treatment.
Предложенные эмульсии обладают определенными периодами распада, что позвол ет повысить эффективность обработки призабойной зоны.The proposed emulsions have definite disintegration periods, which makes it possible to increase the efficiency of the bottomhole zone treatment.
Это достигаетс благодар тому, что примен ют эмзльгаторы-аминосоединени либо моноэтаноламиды, либо амины, либо диаминдиолеат , вз тые в следуюнгих количествах (в вес. %): моноэтаноламиды 0,7-1,0, амины 0,2-1,0, диаминдиолеат 0,2-0,6.This is achieved by using emulsifiers-amino compounds, either monoethanolamides, or amines, or diamine dioleate, taken in the following quantities (% by weight): monoethanolamides 0.7-1.0, amines 0.2-1.0, diamine dioleate 0.2-0.6.

Кроме того, предложенные гидрофобные эмульсии обеспечивают также защиту под-i земного оборудовани от кислотной коррозии .In addition, the proposed hydrophobic emulsions also protect the under-i terrestrial equipment from acid corrosion.
Предмет изобретени Subject invention
Гидрофобные кислотные эмульсии дл обработки призабойной зоны карбонатного пласта в глубоких скважинах на основе нефти, дизельного топлива или керосина и сол ной кислоты с добавками эмульгаторов, отличающиес те.м, что, с целью получени термостойких эмульсий с определениыми периодами распада и повыщени эффективности обработки призабойной зоны, применены в качестве эмульгаторов аминосоединени в следующих количествах (в вес. /о): моноэта)голамиды 0,7-1,0, либо амины 0,2-1,0, либо диаминднолеат 0,2-0,6.Hydrophobic acid emulsions for treating the bottomhole zone of a carbonate reservoir in deep wells based on oil, diesel fuel or kerosene and hydrochloric acid with emulsifier additives, differing in that with the aim of obtaining heat resistant emulsions with determined periods of decomposition and improving the efficiency of bottomhole treatment , used as emulsifiers of the amine compound in the following amounts (in weight / o): monoethyl) golamides 0.7-1.0, or amines 0.2-1.0, or diamine neatolate 0.2-0.6.
