在 F R H A和 F R H B 的基础上,由极性化沥青、皂化沥青、固体润滑剂、调质剂等制成了粉状的防塌润滑剂 F R H C,在制备中实现了沥青在粉末状态下的皂化。室内性能评价结果表明, F R H C 具有良好的抑制泥页岩膨胀的性能、降滤失特别是高温高压滤失的性能及降低泥饼粘滞系数的性能,与川西南矿区目前常用的聚合物、聚磺等水基钻井液配伍性良好,使用方便。
On the basis of F R H A and F R H B, powdered anti-collapse lubricant F R H-C is made from polar bitumen, saponified bitumen, solid lubricant, Preparation of the pitch in the powder to achieve saponification. Indoor performance evaluation results show that F R H C has good performance of inhibiting the expansion of shale, filtration loss especially high temperature and high pressure filtration performance and reduce the performance of the mud cake viscosity coefficient, and Southwest mining area currently used Polymer, polysulfone and other water-based drilling fluid compatibility, easy to use.
