Gerneral Overview
Drilling grade CMC-HV is a high-viscosity thickening anionic cellulose ether specialized for low-solid drilling fluids. Our drilling mud thickener significantly increases plastic viscosity and yield point.
Core Product Advantages
1. High Thickening & Shear Boosting Efficiency: High thickening efficiency greatly increases viscosity and yield point at low dosage, suitable for low-solid and low-density drilling fluids.
2. Enhanced Cuttings Suspension & Carrying: Significantly enhances cuttings carrying and suspension capacity, prevents cuttings settlement during shutdown and ensures clean bottom hole.
3. Auxiliary Fluid Loss Reduction: Provides certain fluid loss effect while viscosifying, improves filter cake quality and assists wellbore stability.
4. Low-solid System Adaptation: Optimized for low-solid drilling fluids, maintains excellent viscosifying effect under low solid content conditions.
Product Specifications
Drilling Grade sodium carboxymethyl cellulose CMC-HV is a high-viscosity thickening anionic cellulose ether and a cost-effective rheology modifier specialized for low-solid drilling fluids. With high thickening efficiency, it can significantly increase the plastic viscosity and yield point of drilling fluids, enhance drill cuttings suspension and carrying capacity, and meanwhile provides basic fluid loss effect to improve filter cake quality and assist in wellbore wall protection. With good compatibility with conventional drilling fluid additives, it is applicable to low-solid, low-density fresh water drilling fluids in shallow well sections, as well as well washing fluids and completion fluid systems, meeting the cuttings carrying and wellbore stability requirements of conventional shallow well drilling.
