摘　　要：提出用10％膨润土浆高温热滚法来评价聚合物降粘剂的抑制性,并以高温热滚后旋转粘度计测出的600r/min读数作为衡量标准。介绍该方法的实验过程,初步探讨了其工作原理。用此方法不需要精密的仪器,且测试程序简单,易操作,是目前评价降粘剂抑制性较为可行的一种方法。A new testing method for the inhibity evaluation of polymer thinner is presented . Testing procedure comprises (1) preparing base mud with 10 % clay concentration , aging 72 hours at room temperature , (2) having stirred 400 mL base mud for 5 minutes . adding 1. 2 grams thinner , determining the reading of Fann35 viscometer at 600 r/min , (3) hot aging for 16 hours at 160℃ , (4) determining the reading of viscometer at 600 r/min at room temperaturefor mud after hot aging . This method is simple .
