HIEMUL 超高温主乳化剂 Ultra-High Temperature Primary Emulsifier
简介Introduction
HIEMUL是专为超高温油基钻井液设计的乳化剂，通过强界面吸附与双电层稳定机制，显著降低油水界面张力，形成耐高温高压的稳定乳液，有效控制滤失并维持流变性能，保障深井超深井作业安全******。
HIEMUL is an emulsifier specifically designed for ultra-high temperature oil-based drilling fluids. It significantly reduces the oil-water interfacial tension through strong interfacial adsorption and double electric layer stabilization mechanisms, forming a stable emulsion that is resistant to high temperatures and pressures. This effectively controls filtration loss and maintains rheological properties, ensuring the safety and efficiency of deep and ultra-deep well operations.
性能及优点Performance and Advantages
l 推荐加量：4%~8%；
l 抗温性强，体系抗温性220℃以上；
l 流变性优异，220℃老化前后流变性变化不大，粘切适中；
l 滤失量低：220℃老化后高温高压滤失量小于6.0mL；
l 抗污染性能优异：抗钻屑、地层水污染能力强，钻屑污染后破乳电压和滤失量变化不大。
l Recommended dosage: 4% to 8%;
l Strong temperature resistance, with the system capable of withstanding temperatures above 220°C;
l Excellent rheological properties, showing minimal changes in rheology before and after aging at 220°C, with appropriate viscosity and yield point;
l Low fluid loss: The high-temperature, high-pressure (HTHP) fluid loss after aging at 220°C is less than 6.0 mL;
l Outstanding contamination resistance: Strong resistance to contamination from drill cuttings and formation water, with minimal changes in demulsification voltage and fluid loss after drill cuttings contamination.
