Title
(RU) ЦЕМЕНТНЫЙ ФЛЮИД ДЛЯ ПРОМЫВАНИЯ СКВАЖИН, СПОСОБЫ ПРОИЗВОДСТВА И СПОСОБЫ ПРИМЕНЕНИЯ
Abstract
(RU)

Цементный флюид для промывания скважин, применяемый в стволе скважины, включает водный цементный флюид-носитель для промывания скважины и предварительно приготовленный синтетический полимер, набухающий в водной несущей цементного флюида, в количестве, эффективном для вытеснения раствора для бурения в процессе цементирования. Преимущественно, полимер - это частицы, которые образуют гидратированный блок частиц. Способ цементирования ствола скважины, включающий раствор для бурения, состоит из закачивания в ствол скважины цементного флюида для промывания скважины, описанной в данном документе, для вытеснения раствора для бурения; закачивания цементной суспензии в ствол скважины после закачивания цементного флюида для промывания скважины и затвердевания цемента в суспензии для цементирования ствола скважины.
