HarCOAT油基辅乳化剂 Oil-based Secondary Emulsifier
简介Introduction
HarCOAT是一款高性价比油基钻井液辅乳化剂，专为成本敏感工况设计。通过优化协同效应增强主乳化剂性能，有效提升乳液稳定性与抗温和抗污染能力，显著降低HTHP滤失。在保障基础流变和井壁稳定的同时，大幅降低钻井液综合成本，重复利用效率高，适用于浅中层井及批量化作业场景。
HarCOAT is a cost-effective oil-based drilling fluid secondary emulsifier, specifically designed for cost-sensitive operating conditions. It enhances the performance of the primary emulsifier through optimized synergistic effects, effectively improving emulsion stability, temperature resistance, and contamination resistance while significantly reducing high-temperature high-pressure (HTHP) fluid loss. While ensuring fundamental rheological properties and wellbore stability, this solution significantly reduces overall drilling fluid costs with high reusability efficiency, making it particularly suitable for shallow-to-medium depth wells and batch operation scenarios.
