Material Description
Natural cellulose is modified by etherification to obtain anionic polymer powder with sodium carboxylate active groups, focusing on protecting the gel and reducing filtration loss, with weak thickening effect, optimizing the quality of mud cake, and stabilizing the water-based drilling fluid colloid system.
 
Core selling point
1. Excellent filtration reduction effect, forming thin, dense and smooth mud cake
2. Low viscosity characteristic, will not cause excessive viscosity and shear of drilling fluid
3. Possess certain salt and calcium resistance, suitable for freshwater and low salt drilling fluids
4. Protect the gel to stabilize the colloid and maintain stable mud performance
5. Excellent compatibility, can be used in combination with various water-based drilling fluid treatment agents
6. Suitable for medium to high-density drilling fluids, easily dispersed on site
 
Product Advantages
-Effectively control the filtration loss, reduce the invasion of filtrate into the formation, and assist in protecting the wellbore
-Low viscosity increase, the use of high-density drilling fluid will not cause the mud to become too thick, and the rheological properties are easy to control
-Has a certain tolerance to calcium and magnesium ions, suitable for shallow, deep, freshwater, and low salt working conditions
-Good protective effect, preventing clay particle aggregation, and stable performance of drilling fluid system
-Good dispersion of powder, less prone to clumping during feeding, 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. Prepare high-density drilling fluid or strictly control filtration and viscosity during segmented replenishment.
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
Sealed and moisture-proof, avoiding exposure to sunlight and rain; Use up as soon as possible after opening; Wear dust-proof protective equipment during operation.
