Core Product Advantages:
1. Balanced Overall Performance: Takes into account both fluid loss control and rheology adjustment, is highly versatile, and meets most conventional drilling operation needs.
2. Uniform Substitution & Fast Dissolution: Uniformly distributed degree of substitution ensures fast dissolution and quick effect, improving mud mixing efficiency.
3. Good Temperature & Salt Resistance: Withstands temperatures up to 150℃, possesses good salt and calcium tolerance, and adapts to fresh water, seawater, and conventional salinity systems.
4. High Cost Performance: Balances performance and cost, making it an economical and high-performance choice for conventional drilling operations.
Technical Parameters:
Drilling fluid grade polyanionic cellulose PAC-R is a general-purpose medium-high viscosity anionic cellulose ether, a cost-effective conventional drilling fluid additive that combines fluid loss control and rheology adjustment. With uniform substitution and fast dissolution, it can stabilize drilling fluid viscosity, improve filter cake quality and reduce API fluid loss. Meanwhile, it has good salt resistance, calcium resistance, and temperature resistance; it can encapsulate drill cuttings and inhibit shale hydration swelling, maintains stable performance over a wide pH range, and has good compatibility with most drilling fluid additives. It is applicable to water-based drilling fluids and workover fluid systems with fresh water, seawater, and conventional salinity.
