聚丙烯酰胺钾盐用于井下不分散低固性泥浆、聚合物体系的剪切稀释、防塌絮凝。聚丙烯酰胺钾盐具有抑制泥页岩及钻屑分散作用，兼有降失水、改善流型和增加润滑等性能。可以有效的抑制地层造浆并能与多种处理剂配伍。能改善钻井液的流变性能，有效地包被钻屑，抑制地层造浆。钾离子的存在，能防止软泥页岩和脆硬性泥页岩的水化和剥落，起到稳定井壁的作用。
       Polyacrylamide potassium salt is used for shearing, diluting and anti-sloughing of Downhole non-dispersible low-solid mud and polymer system. Potassium Polyacrylamide can inhibit the dispersion of mud shale and cuttings, and has the properties of reducing water loss, improving flow pattern and increasing lubrication. It can effectively inhibit formation pulping and can be compatible with various treatment agents. It can improve the rheological property of drilling fluid, effectively encase drilling cuttings and restrain formation mud making. The existence of potassium ion can prevent the hydration and spalling of soft shale and brittle shale and stabilize the borehole wall.
