Abstract

Рассматривается способ снижения крутящего момента бурильной колонны, используемой в бурении подземной скважины, который включает введение в буровую жидкость композиции, включающей основную жидкость и коллоидальный твердый материал с полимерным покрытием. Коллоидальный твердый материал с полимерным покрытием включает твердые частицы, имеющие средневзвешенный диаметр частиц (d) менее 10 мкм, и полимерный диспергатор, нанесенный на поверхность твердых частиц в процессе дробления (т.е. измельчения), используемого для получения коллоидальных частиц. Полимерным диспергатором может быть водорастворимый полимер, имеющий молекулярную массу по меньшей мере 2000 Да. Твердый дисперсный материал может быть выбран из материалов, имеющих относительную плотность по меньшей мере 2,68, и, предпочтительно, тертый дисперсный материал может быть выбран из сульфата бария (барита), карбоната кальция, доломита, ильменита, гематита, оливина, сидерита, сульфата стронция, их комбинаций и смесей их и других подобных твердых материалов, которые должны быть известны специалисту в данной области техники.A method for reducing the torque of a drill string used in drilling an underground well is considered, which involves introducing into the drilling fluid a composition comprising a base fluid and a polymer-coated colloidal solid material. The colloidal solid material with a polymer coating includes solid particles having a weighted average particle diameter (d) of less than 10 microns, and a polymer dispersant deposited on the surface of solid particles during the crushing process (i.e. grinding) used to produce colloidal particles. The polymer dispersant may be a water-soluble polymer having a molecular weight of at least 2000 Da. The solid particulate material may be selected from materials having a relative density of at least 2.68, and, preferably, the particulate dispersed material may be selected from barium sulfate (barite), calcium carbonate, dolomite, ilmenite, hematite, olivine, siderite, sulfate strontium, their combinations and mixtures of them and other similar solid materials that should be known to a person skilled in the art.
