High viscosity anionic cellulose HV-PAC for drilling fluids

Main ingredients

High viscosity anionic cellulose PAC-HV for drilling fluid is a water-soluble cellulose ether derivative obtained by chemical modification of natural cellulose. It is an important water-soluble cellulose ether and is widely used in oil drilling, especially in saltwater wells and offshore oil drilling.

Main component molecular structure - OCH2COONa

Nature and Use

This product is a white or light yellow powder that is easy to absorb moisture, soluble in water, has a significant adhesive effect, strong salt resistance, and significant water loss reduction effect. Effectively increasing the viscosity of drilling fluid is beneficial for suspending rock cuttings, cleaning wellbore, greatly improving mud cake quality, effectively reducing filtration loss, and has strong salt and calcium resistance, making it suitable for preparing saltwater drilling and calcium treated drilling fluids.

Specification

Product features

1. High substitutability: substitution value 0.90-1.4;
2. Heat resistance stability, acid, alkali, and salt resistance, suitable for various polar harsh environments;
3. Good phase solubility and solubility greatly improve the convenience of use and production efficiency;
4. Good stability: The aqueous solution has photo stability and a longer shelf life; Strong resistance to bacterial and mold growth, no fermentation;
5. The extremely low usage has to some extent reduced the operating costs of enterprises, and has a high cost-effectiveness advantage. The production process is green and environmentally friendly.

Usage

Just mix it directly into the drilling fluid.

Recommended dosage: 0.5% -1.5%.
