摘　　要：阳离子单体和褐煤在一定条件下与催化剂的作用进行接枝，合成具阳离子褐煤，具阳离子褐煤加入钻井液中，有很好的抑制性能和良好的防塌性能。文中分析了具阳离子褐煤在室内试验的合成方法、对页岩的抑制性、对钻井液性能的影响及聚合物复配的效果进行分析和评价。On certain conditions,through catalysis,cation monomer and lignite can synthesize lignite with cation.When lignite with cation is added into drilling fluid,is has good anti-sloughing property and inhibitive.Its indoor experimental synthetic method,inhibitive to shale and effects on drilling fluid properties are discussed.Meantime,its complex reaction with polymer is analysed and evaluated in this paper.
