摘要
Abstract
In this paper, the filtrate reducer LS-1 is synthesized based on acrylamide, 2-acrylamido-2-methylpropane sulfonic acid, diallyldimethylammonium chloride and ester, which is prepared by oxidation-reduction system in water-solution condition. The structure of LS-1 is characterized by IR, also it can form membrane on the filter cakes that is approved by SEM. The experimental results show that the nitration rate is 6.8 mL in fresh water drilling fluid system with the concentration of 0.5%, and the nitration rate can be reduced shaply in salt water drilling fluid system with the concentration of 1.5%, even after aged at the temperature of 150-160 ℃.关键词
