Abstract
Изобретение относится к композиции бурового раствора на водной основе, содержащей карбоксиметилцеллюлозу (КМЦ), причем КМЦ отличается гелеобразованием при 25°С после растворения в условиях высокого сдвига в 0,3 мас.% водного раствора хлорида натрия, причем конечное содержание КМЦ в водном растворе хлорида натрия составляет 1 мас.% для КМЦ со степенью полимеризации (DP) >4000, 1,5 мас.% для КМЦ с DP >3000-4000, 2 мас.% для КМЦ с DP 1500-3000 и 4 мас.% для КМЦ с DP <1500, причем гель является жидкостью с динамическим модулем накопления при сдвиге (G'), превышающим модуль потерь (G") во всем диапазоне частот 0,01-10 Гц, при измерении на колебательном реометре, работающем при нагрузке 0,2.
