Abstract

Изобретение касается бурового раствора на водной основе, используемого в процессе извлечения углеводорода, например, при бурении, гидравлическом разрыве пласта, гравийной набивке и капитальном ремонте скважины. Согласно настоящему изобретению буровой раствор содержит снижающую водоотдачу добавку и наполнитель для борьбы с поглощением бурового раствора, которые являются гидрофобными по природе, гидрофобно модифицированными или смачиваемыми нефтью. Буровой раствор вырабатывает активную фильтрационную корку, которая, образуясь, является непроницаемой для водной фазы, что снижает водоотдачу и обеспечивает снижение нарушения эксплуатационных качеств пласта, в то же время является проницаемой для противотока углеводородов во время процесса извлечения углеводорода.Международная заявка была опубликована вместе с отчетом о международном поиске.
