Abstract

Изобретение относится к способу, включающему в себя обеспечение бурового раствора, раствора для заканчивания скважины или жидкости для капитального ремонта скважины, содержащей жидкость на водной основе и полимер неионного сложного эфира целлюлозы, имеющий гидроксиэтильные группы и замещенный далее одним или более гидрофобным заместителем, и помещение бурового раствора, раствора для заканчивания скважины или жидкости для капитального ремонта скважины в подземный пласт.The invention relates to a method comprising providing a drilling fluid, a well completion solution or a well overhaul fluid containing a water-based fluid and a polymer of a non-ionic cellulose ester, having hydroxyethyl groups and subsequently replaced by one or more hydrophobic substituents, and placing the drill a solution, a well completion solution, or a fluid to overhaul a well in a subterranean formation.
