Abstract

Водные буровые растворы (ВБР) включают в качестве добавки продукт реакции полигидроксиалкана с окисью алкилена. В качестве полигидроксиалкана желательно использовать моносахарид и предпочтительно сорбит. Окись алкилена может включать окись этилена (ЭО), окись пропилена (ПО) и/или окись бутилена (БО). Хорошие результаты получают при использовании в качестве добавки сорбит + 18 ЭО, сорбит + 9 ПО, сорбит + 4 ЭО + 6 БО, сорбит + 6 ЭО + 6 БО или сорбит + 6 БО. Как было установлено в ходе лабораторных экспериментов, ингибирующая способность предлагаемых буровых растворов в отношении глин превосходит аналогичные показатели известного ВБР, содержащего многоатомные спирты, особенно при отсутствии добавок ионов калия. Предлагаемое изобретение существенно превосходит известные решения с точки зрения защиты окружающей среды.Международная заявка была опубликована вместе с отчетом о международном поиске.
