Abstract
Инвертно-эмульсионный буровой раствор и способ бурения с использованием такого раствора, имеющего улучшенные реологические свойства при низкой удельной массе и в условиях высоких температур. Улучшенные реологические свойства обеспечиваются с помощью добавления гидрофобных аминов, наиболее предпочтительно димерных диаминов.Invert-emulsion drilling fluid and method of drilling using such a solution having improved rheological properties at low specific gravity and at high temperatures. Improved rheological properties are provided by the addition of hydrophobic amines, most preferably dimeric diamines.
