摘要
以膨润土为载体，采用自由基聚合方式，在其晶体结构上接枝丙烯酰胺高分子链，合成出膨润土接枝聚合物。经性能评价表明，膨润土接枝聚合物在钻井液中具有优良降滤失性能，滤饼薄且致密，流变性好。
The article studys a new type of the bentonite graft polymer filtrate reducer for drilling fluid according to the principle of the radical polymerization, by means of the carrier of bentonite, grafting a micromolecular chain with acrylamide onto the clay crystal construction. The evaluation shows that new type of the filtrate reducer for drilling fluid has excellent in reducing filtrate performance, thinning and thickening in filter cake, good theological property.
