MOCOAT 大位移井辅乳化剂 Auxiliary Emulsifier for Extended-Reach Wells
简介Introduction
MOCOAT是专为大位移井油基钻井液开发的******辅乳化剂。其通过增强界面膜强度,显著提高乳状液高温稳定性(>150℃)及抗固相污染能力,与主乳化剂协同作用降低滤失量、优化流变性能。该产品具备优异的抗钙镁盐及剪切稳定性,可确保长水平段井眼清洁与润滑效果,有效降低扭矩摩阻,减少井下作业风险,提高钻井作业效率。
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.
