Material Description
A linear water-soluble polymer is formed by copolymerization of cationic, anionic, and nonionic vinyl monomers. The molecular chain carries multiple active groups simultaneously, which can strongly encapsulate and adsorb drilling cuttings and shale particles, inhibit clay hydration and dispersion, and adapt to zwitterionic water-based drilling fluid systems.
 
Core selling point
1. Strong packaging is suppressed to prevent the hydration and dispersion of shale and stabilize the wellbore
2. Salt resistant and calcium resistant drilling fluids can be used in freshwater, saltwater, and composite saltwater drilling fluids
3. Improve the viscosity and shear of drilling fluid, and enhance the ability to carry suspended debris
4. Resistant to solid phase pollution of rock powder, conducive to the removal of harmful solid phases by solid control equipment
5. Excellent compatibility, can be used in combination with various water-based drilling fluid treatment agents
6. Compatible with zwitterionic drilling fluid system, convenient for on-site use
 
Product Advantages
-Excellent wrapping ability, wrapping drill cuttings and shale particles, inhibiting hydration expansion and dispersion, reducing the risk of well collapse, and ensuring the safety of drilling operations
-Outstanding salt and calcium resistance, high mineralization formations still maintain good inhibitory effects
-Moderately increasing viscosity and cutting, improving the sand carrying capacity of drilling fluid suspension, ensuring smooth return of drilling cuttings
-It can reduce the harmful solid phase of submicron system, alleviate rock powder pollution, and help improve mechanical drilling speed
-Good synergistic effect with zwitterionic treatment agents, suitable for various working conditions in shallow, medium and deep wells
 
Usage
1. It can be used alone or in combination with other water-based drilling fluid treatment agents.
2. When encountering mud shale or easily collapsed formations during drilling, it is often supplemented in sections and used in conjunction with zwitterionic viscosity reducers.
3. It is recommended to refer to the working conditions for the recommended dosage on site. It is suggested to conduct indoor trials to determine the optimal dosage before on-site deployment.
4. Normal circulation stirring, sufficient dissolution and dispersion can be used for drilling operations.
