The role of carboxymethylcellulose in mud

Carboxymethyl cellulose can be mixed directly with water. After it is completely combined with water, there is no solid-liquid separation between the two, so it also plays a great role in mud, drilling and other projects. Let's take a look. 1. After adding carboxymethylcellulose to the mud, the drilling rig can have a lower initial shear force, making it easy for the mud to release the gas trapped in it, and at the same time, the debris is quickly discarded in the mud pit. 2. Like other suspensions, drilling mud also has a certain shelf life. Adding carboxymethyl cellulose stabilizes it and extends its shelf life. 3. As a drilling mud cleaning fluid treatment agent, carboxymethylcellulose can resist contamination from various soluble salts. 4. Mud containing carboxymethyl cellulose can make the well wall thinner and stronger and reduce water loss. 5. Slurry containing carboxymethyl cellulose has good stability and can reduce water loss even if the temperature is above 150°C. 6. Muds containing carboxymethylcellulose are rarely affected by mold. Therefore, a high pH value must be maintained and no preservatives are required. Carboxymethyl cellulose can be used in industries with good stability and high process requirements. Its aqueous solution can be added to mud to make the mud more resistant to salt, acid, calcium and high temperature. There are other performances.
