MOCOAT 大位移井輔乳化劑 Auxiliary Emulsifier for Extended-Reach Wells
簡介Introduction
MOCOAT是專為大位移井油基鉆井液開發(fā)的******輔乳化劑。其通過增強界面膜強度，顯著提高乳狀液高溫穩(wěn)定性（＞150℃）及抗固相污染能力，與主乳化劑協(xié)同作用降低濾失量、優(yōu)化流變性能。該產(chǎn)品具備優(yōu)異的抗鈣鎂鹽及剪切穩(wěn)定性，可確保長水平段井眼清潔與潤滑效果，有效降低扭矩摩阻，減少井下作業(yè)風險，提高鉆井作業(yè)效率。
Specially developed for extended-reach well oil-based drilling fluids, MOCOAT significantly enhances high-temperature stability (>150℃) and solid-phase contamination resistance by reinforcing interfacial film strength. Working synergistically with primary emulsifiers, it effectively reduces fluid loss and optimizes rheological performance. Featuring outstanding calcium/magnesium salt resistance and shear stability, this product ensures effective wellbore cleaning and lubrication in long lateral sections, substantially reducing torque/drag while mitigating downhole risks to improve drilling efficiency.
性能及優(yōu)點Performance and Advantages
l 推薦加量：0.8%~1.5%；
l 顯著增強高溫界面膜韌性，提升乳液熱穩(wěn)定性，保障體系長效穩(wěn)定；
l 優(yōu)異抗高固相污染及鈣鎂鹽污染，維持乳液結構完整，降低復雜地層引起的性能波動；
l 與主乳化劑協(xié)同增效，優(yōu)化流變性能并降低高溫高壓濾失量，提高井眼清潔效率，增強井壁封固穩(wěn)定性。
l Recommended dosage: 0.8% to 1.5%;
l Significantly enhances the toughness of the high-temperature interfacial film, improving the thermal stability of the emulsion and ensuring long-term system stability;
l Exceptional resistance to high solids contamination and calcium/magnesium salt contamination, maintaining emulsion structural integrity and minimizing performance fluctuations caused by complex formations;
l Synergistic enhancement with primary emulsifiers—optimizes rheological properties, reduces HTHP (High-Temperature High-Pressure) fluid loss, improves wellbore cleaning efficiency, and strengthens wellbore wall stabilization.
