Gerneral Overview
Drilling grade CMC-MV is a general-purpose medium-viscosity fluid loss additive with dual functions. As a mainstream cmc in drilling mud, it stabilizes drilling fluid rheology and improves cuttings carrying capacity.
Core Product Advantages
1. Dual Effect of Viscosifying & Fluid Loss Control: Combines viscosity building and fluid loss reduction in one product, simplifies drilling fluid treatment process.
2. Enhanced Cuttings Carrying Capacity: Increases yield point of drilling fluid, enhances cuttings carrying capacity, keeps bottom hole clean and reduces regrinding.
3. Optimized Filter Cake Quality: Forms uniform texture filter cake, reduces filtration rate and protects wellbore and reservoir.
4. Basic Salt & Calcium Resistance: Good basic salt and calcium tolerance, adapts to fresh water and brackish water drilling fluid systems.
Product Specifications
Drilling Grade sodium carboxymethyl cellulose CMC-MV is a general-purpose medium-viscosity anionic cellulose ether, a mainstream cost-effective additive for conventional drilling operations with dual functions of viscosity building, yield point improvement and fluid loss control. It can stabilize the rheological properties of drilling fluids, improve basic cuttings carrying capacity, reduce fluid loss and optimize filter cake condition. With good basic salt and calcium resistance, excellent dissolution and dispersion performance, stable batch quality and outstanding compatibility with most drilling fluid additives, it is widely used in fresh water and brackish water drilling fluids, workover fluids and fracturing fluid systems for medium-shallow wells, and adapts to drilling operations in most conventional formations.
