Abstract

Описан скважинный флюид, имеющий сплошную неводную фазу и неорганические частицы, где указанные частицы покрыты практически постоянно адсорбированными амфифильными молекулами, обуславливающими липофильное поведение указанных частиц в рабочих условиях.A well fluid having a solid non-aqueous phase and inorganic particles is described, where the particles are coated with almost constantly adsorbed amphiphilic molecules causing the lipophilic behavior of the particles under operating conditions.
