Gerneral Overview
Drilling grade CMC-LV is a low-viscosity specialized fluid loss control additive for conventional water-based drilling fluids. As a core cmc in drilling mud, our product reduces fluid loss without increasing system viscosity.
Core Product Advantages
1. Efficient Fluid Loss Control: Effectively reduces drilling fluid filtration, forms a thin and compact filter cake, protects wellbore stability and reduces formation damage.
2. Minimal Viscosity Increase: Has minimal impact on rheological properties, enables precise control of equivalent circulating density, and adapts to high-density drilling fluids.
3. Basic Salt & Calcium Resistance: Possesses certain salt and calcium tolerance, maintains stable performance in brackish water and conventional calcium-bearing formations.
4. Fast Dissolution Speed: Good powder dispersibility and rapid dissolution take effect quickly, improving mud mixing efficiency.
Product Specifications
Drilling Grade sodium carboxymethyl cellulose CMC-LV is a low-viscosity, cost-effective anionic cellulose ether and a specialized fluid loss additive for conventional water-based drilling fluids. It has minimal impact on the rheological properties of drilling fluids, reduces fluid loss and improves filter cake quality without basically increasing system viscosity, and has basic salt and calcium resistance. With fast dissolution and good compatibility with conventional drilling fluid additives, it is applicable to high-density, high-solid fresh water drilling fluids for medium-shallow wells, as well as workover fluids and cementing slurry systems. It can effectively control fluid loss and protect wellbore walls, meeting the requirements of conventional low-cost drilling operations.
