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定性（＞150℃）及抗固相污染能力，與主乳化劑協同作用降低濾失量、優化流變性能。該產品具備優異的抗鈣鎂鹽及剪切穩定性，可確保長水平段井眼清潔與潤滑效果，有效降低扭矩摩阻，減少井下作業風險，提高鉆井作業效率。
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.
