HarCOAT油基輔乳化劑 Oil-based Secondary Emulsifier
簡介Introduction
HarCOAT是一款高性價比油基鉆井液輔乳化劑，專為成本敏感工況設計。通過優化協同效應增強主乳化劑性能，有效提升乳液穩定性與抗溫和抗污染能力，顯著降低HTHP濾失。在保障基礎流變和井壁穩定的同時，大幅降低鉆井液綜合成本，重復利用效率高，適用于淺中層井及批量化作業場景。
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.
