HICOAT 超高温辅乳化剂 Ultra-High Temperature Auxiliary Emulsifier
简介Introduction
HICOAT是专为超高温（220℃）极端工况研发的油基钻井液辅乳化剂。通过分子结构设计，在极限温度下保持高强度界面吸附性能，协同主乳化剂显著提升乳液热稳定性与抗破乳能力。具有优异的高温高压滤失控制性及抗盐钙污染性能，有效维持深井、超深井钻井液流变稳定，降低高温增稠风险，保障井下安全与作业效率。
HICOAT is an auxiliary emulsifier specifically designed for oil-based drilling fluids operating under ultra-high temperature (220°C) extreme conditions. Through innovative molecular structure design, it maintains strong interfacial adsorption capacity at extreme temperatures, significantly enhancing the thermal stability and demulsification resistance of the emulsion when used synergistically with the primary emulsifier. It possesses excellent HTHP (High Temperature High Pressure) fluid loss control and resistance to salt and calcium contamination, effectively maintaining the rheological stability of drilling fluids in deep and ultra-deep wells, reducing the risk of high-temperature thickening, and ensuring downhole safety and operational efficiency.
