Oil Drilling CMC

CMC Petroleum Grade

Oil Drilling CMC, as a water-soluble colloid in drilling mud systems, has a high water loss control capability. Adding a small amount of CMC can keep the water level at a high level. In addition, it has good temperature resistance and excellent salt resistance. Under certain salt concentrations, it can still have good water loss reduction capability and maintain certain rheological properties. When dissolved in salt water or water, the viscosity hardly changes, making it particularly suitable for the requirements of offshore drilling and deep wells.

Petroleum Grade Carboxymethylcellulose Features

1. Excellent fluid loss control capability; fluid loss can be controlled at a high level with a relatively low dosage without affecting other mud properties.
2. Produces high-quality, firm, and tough mud cake.
3. Excellent control over mud rheology, exhibiting good non-Newtonian fluid properties. Furthermore, CMC, when used as a cementing fluid, can prevent fluid from entering pores and fractures; when used as a fracturing fluid, it can control fluid loss into the well.

Functions:

1. Thickener: CMC Oil Drilling Grade increases the viscosity of drilling fluid, enhancing its ability to carry cuttings and preventing cuttings deposition at the bottom of the well.
2. Filtration Reducer: Forms a dense filter cake on the wellbore, reducing drilling fluid loss to the formation and maintaining wellbore stability.
3. Salt Resistance: Low-substitution CMC can be used in high-salinity drilling fluids to inhibit clay swelling.

PERFORMANCE

1. Green environmental protection, non-toxic, tasteless and harmless, biodegradable, harmless to agricultural production and the surrounding environment;
2. The mud containing CMC can effectively protect the well wall and form a dense filter cake;
3. It can clean cuttings in time and make the drilling fluid protect low solid phase and low dispersion of clay.
4. Good compatibility with other polymers; Strong suspension ability; 
5. It is suitable for drilling needs of various geological conditions; 
6. Low permeability will reduce water loss; 
7. It is an excellent fluid loss reducer.
 

FAQ

Q: How are the salt and temperature resistance of your Oil Drilling Grade CMC?
A: Our products perform very well. Whether in deep-sea drilling or high-salt formations, our CMC maintains stable performance, ensuring the safety and efficiency of drilling projects.

Q: Drilling site conditions are complex. Will your products ferment, spoil, or experience a sudden drop in viscosity?
A: Absolutely not. Our own factory adds professional anti-fermentation ingredients during production and strictly controls the sealing. The product's performance is very stable during storage and use.

Q: We operate overseas or in remote areas. Can you keep up with the delivery time and after-sales service?
A: You don't need to worry about that. As the source factory, we have sufficient production capacity and mature export packaging and logistics experience, enabling us to ship goods to all parts of the world on time.
