MOEMUL 大位移井主乳化劑 Primary Emulsifier for Extended-Reach Wells
簡介Introduction
MOEMUL主乳化劑是一款專為海上大位移井作業(yè)設計的表面活性劑，可顯著降低油水界面張力，形成穩(wěn)定的乳化體系，保障油基鉆井液在低油水比條件下的******作業(yè)；其配制的油基鉆井液具有低粘高切特性，優(yōu)異的攜砂性能，適合海上大位移井作業(yè)。
MOEMUL Primary Emulsifier is a surfactant specifically designed for offshore extended-reach drilling operations. It significantly reduces the oil-water interfacial tension, forming a stable emulsion system. This ensures efficient operations of oil-based drilling fluids under low oil-to-water ratios. The oil-based drilling fluids formulated with MOEMUL have low viscosity and high gel strength, with excellent sand-carrying capabilities, making them suitable for offshore extended-reach drilling operations.
性能及優(yōu)點Performance and Advantages
l 推薦加量：3.0%~6.0%；
l 塑性粘度低，具有低粘高切特點，巖屑攜帶能力強；
l 當量循環(huán)密度（ECD）低，體系具有低粘度、低靜切力特征，可有效降低窄安全密度窗口地層的漏失風險；
l 儲層保護性能優(yōu)異：巖心污染后滲透率恢復值達90.0%以上，儲層保護效果顯著。
l Recommended dosage: 3.0% to 6.0%;
l Low plastic viscosity with low-viscosity/high-shear characteristics, demonstrating excellent cuttings transport capacity;
l Reduced equivalent circulating density (ECD) - the system exhibits low viscosity and low gel strength properties, effectively mitigating lost circulation risks in narrow drilling margin formations;
l Superior reservoir protection performance: Achieves >90.0% permeability recovery after core contamination, indicating outstanding formation protection efficacy.
