摘要
可逆乳状液可集中不同类型乳状液的优势发挥最佳效果,使用改性固废材料制备可逆乳状液可实现减排增效。基于前期开发的基于固废材料的新型改性颗粒型可逆乳化剂,探讨配液水对其性能的影响规律,通过实验研究明确:水相为湖水1号、湖水2号条件下均可形成可逆乳状液;水相为湖水2号的油包水乳状液的破乳电压明显高于水相为湖水1号的油包水乳状液,即前者稳定性高于后者。但水相为湖水1号的乳状液加酸转相所需酸液体积更少,且相同条件下转相后的水包油乳状液液滴分散性更好,整体电导率更高。同时,水相为湖水1号的水包油乳状液相比于水相为湖水2号的水包油乳状液加碱转相所需碱液体积更多。相关研究成果可为可逆乳化钻井液体系的推广应用提供参考。
Reversible invert emulsion can concentrate the advantages of different types of emulsions to get the best effect.Reversible invert emulsion with modified solid waste materials emulsifier can achieve emission reduction and efficiency increase.Based on the new modified particle reversible invert emulsifier developed by the author based on solid waste material in the early stage,this paper discusses the influence law of liquid water on its performance.Through the experimental study,it is clear that reversible invert emulsion can be formed when the water phase is lake-water-1 and lake-water-2.The demulsification voltage of the water-in-oil emulsion with the aqueous phase of lake-water-2 is obviously higher than that of the water-in-oil emulsion with the aqueous phase of lake-water-1,that is,the stability of the former is higher than that of the latter.However,the volume of acid required for phase transformation of the emulsion with water phase being lake-water-1 and acid is less,and the droplets of the emulsion after phase transformation have better dispersion and higher overall electrical conductivity under the same conditions.At the same time,the volume of base needed in the oil-in-water emulsion with the aqueous phase of lake-water-1 is larger than that in the oil-in-water emulsion with the aqueous phase of lake-water-2.The relevant research results can provide reference for the popularization and application of reversible emulsified drilling fluid system.
