HIEMUL 超高溫主乳化劑 Ultra-High Temperature Primary Emulsifier
簡介Introduction
HIEMUL是專為超高溫油基鉆井液設計的乳化劑，通過強界面吸附與雙電層穩(wěn)定機制，顯著降低油水界面張力，形成耐高溫高壓的穩(wěn)定乳液，有效控制濾失并維持流變性能，保障深井超深井作業(yè)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.
性能及優(yōu)點Performance and Advantages
l 推薦加量：4%~8%；
l 抗溫性強，體系抗溫性220℃以上；
l 流變性優(yōu)異，220℃老化前后流變性變化不大，粘切適中；
l 濾失量低：220℃老化后高溫高壓濾失量小于6.0mL；
l 抗污染性能優(yōu)異：抗鉆屑、地層水污染能力強，鉆屑污染后破乳電壓和濾失量變化不大。
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.
