Carboxymethyl cellulose can be directly mixed with water, and after it is completely bonded with water, there is no solid-liquid separation between the two, so it also plays a great role in mud, well drilling and other projects. Let’s take a look.
1. After adding carboxymethyl cellulose to the mud, the drilling rig can have a low initial shear force, so that the mud can easily release the gas wrapped in it, and at the same time, the debris is quickly discarded in the mud pit.
2. Like other suspension dispersions, drilling mud has a certain period of existence. Adding carboxymethyl cellulose can make it stable and prolong the existence period.
3. Carboxymethyl cellulose is used as drilling mud washing fluid treatment agent, which can resist the pollution of various soluble salts.
4. The mud containing carboxymethyl cellulose can make the well wall thin and firm, and reduce the water loss.
5. The mud containing carboxymethyl cellulose has good stability and can reduce water loss even if the temperature is above 150℃.
6. Mud containing carboxymethyl cellulose is rarely affected by mold. Therefore, it is necessary to maintain a high pH value, and it is not necessary to use preservatives.
Carboxymethyl cellulose can be used in industries where it can provide better stability and meet higher process requirements, and its aqueous solution can be added to the mud to make the mud more resistant to salt, acid, calcium and high temperature. and other performance.
