Abstract

Способ регулирования давления в затрубном пространстве в подземной скважине, который включает нагнетание в затрубное пространство композиции, включающей основную текучую среду и коллоидный твердый материал, покрытый полимером. Коллоидный твердый материал, покрытый полимером, включает твердые частицы, имеющие средневесовой диаметр (d) меньше двух микрон, и полимерный диспергирующий агент, нанесенный на поверхность твердых частиц во время процесса дробления (т.е. измельчения), применяемого для получения коллоидных частиц. Полимерным диспергирующим агентом может быть растворимый в воде полимер, молекулярная масса которого составляет по меньшей мере 2000 Да. Твердый измельченный материал может быть выбран из материалов плотностью не менее 2,68 и предпочтительно твердый измельченный материал может быть выбран из сульфата бария (барита), карбоната кальция, доломита, ильменита, гематита, оливина, сидерита, сульфата стронция, их комбинаций и смесей и других аналогичных твердых материалов, которые должны быть очевидны для специалиста в данной области.Международная заявка была опубликована вместе с отчетом о международном поиске.
