Product Introduction
A stable emulsion system is key to maintaining the excellent performance of oil-based drilling fluids. Insufficient emulsification can easily lead to oil-water separation, reduced electrical stability, and fluctuations in rheological properties, and may even affect wellbore stability and drilling efficiency. Therefore, selecting a high-performance emulsifier is a critical step in establishing a high-quality oil-based drilling fluid system.
The primary emulsifier for drilling fluids is a highly efficient emulsifier specifically developed for oil-in-water (invert emulsion) drilling fluid systems. It rapidly forms a stable and uniform emulsion, improves the drilling fluid’s electrical stability (ES) and emulsion stability, effectively reduces free water separation, and enhances the drilling fluid’s stability under high-temperature, high-pressure, and complex formation conditions.
With an emulsification rate of ≥90% and electrical stability (ES) of ≥600 V, this product can be widely used in diesel-based, mineral oil-based, and synthetic-based drilling fluid systems. It is one of the core additives in drilling fluid formulations for deep wells, horizontal wells, directional wells, and high-temperature wells.

Frequently Asked Questions
What is the primary function of a primary emulsifier?
It is primarily used to establish and maintain an oil-in-water emulsion system, improve the emulsion stability and electrical stability of drilling fluids, and serves as a key component of oil-based drilling fluids.
Is a higher electrical stability (ES) value always better?
A higher ES value generally indicates a more stable emulsion system that can better adapt to complex downhole environments. However, specific requirements should still be determined comprehensively based on the drilling fluid formulation and on-site operating conditions.
Can it be used with co-emulsifiers?
Yes. Primary emulsifiers are typically used in conjunction with co-emulsifiers to further improve emulsion stability, wetting performance, and the overall performance of the drilling fluid.
Is it suitable for synthetic-based drilling fluids?
Yes, this product is suitable for diesel-based, mineral oil-based, and synthetic-based drilling fluid systems.
