Material Description
Natural cellulose is chemically etherified to obtain anionic polymer powder, which contains a large number of sodium carboxylate active groups and can adsorb the surface of clay particles, playing a role in protecting and increasing viscosity, optimizing the mud cake structure, and stabilizing the water-based drilling fluid colloid system.
 
Core selling point
1. Strong thickening and cutting ability, improving the sand carrying performance of drilling fluid suspension
2. Excellent filtration reduction effect, forming thin, dense and smooth mud cake
3. Possess certain salt and calcium resistance, suitable for freshwater and low salt drilling fluids
4. Good protective effect, maintaining the stability of the mud colloid system
5. Excellent compatibility, can be used in combination with various water-based drilling fluid treatment agents
6. Good solubility and dispersibility, easy on-site mixing operation
 
Product Advantages
-Effectively improve the viscosity and shear force of drilling fluid, enhance the ability to carry suspended debris, and ensure the smooth return of drilling debris
-Reduce filtration loss, minimize filtrate invasion into the formation, and assist in stabilizing the wellbore
-The protective effect is prominent, inhibiting the agglomeration of clay particles and maintaining the stability of mud performance
-Suitable for freshwater and low salt drilling fluid systems in shallow, medium, and deep wells
-Good dispersion of powder feeding, less prone to clumping, and easy maintenance of on-site mud
 
Usage
1. It can be used alone or in combination with other water-based drilling fluid treatment agents.
2. It is necessary to increase the mud adhesion or supplement in sections before encountering a leaking formation during drilling.
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.
 
Storage precautions
