通过测定加有不同外加剂的水泥浆滤液离子组成、讨论滤液中颗粒尺寸分布、测定水泥浆液相电导，分析了加有不同外加剂的水泥水化历程；通过岩心流动实验考察了加有外加剂的水泥浆滤液对百色油田砂岩地层岩心的污染。实验结果表明：外加剂通过影响水泥水化历程改变滤液的离子组成和滤液中颗粒数量。在水泥浆中加入有机酸（酒石酸）可以改变滤液的离子组成，大大减轻滤液对地层渗透率的伤害。 By measuring the ion composition of the filtrate with different admixtures, discussing the particle size distribution in the filtrate, measuring the liquid phase conductance of cement slurry, analyzing the hydration process of cement with different admixtures; The slurry of cement slurry on Baise oilfield sandstone formation core contamination. The experimental results show that the admixture can change the ionic composition of the filtrate and the amount of particles in the filtrate by affecting the course of cement hydration. The addition of organic acid (tartaric acid) to the cement slurry can change the ionic composition of the filtrate and greatly reduce the damage of the filtrate to formation permeability.
