Oil Drilling grade CMC Sodium carboxymethyl celluloseis made of natural cellulose by chemical modification of water-soluble cellulose ether derivatives, is an important water-soluble cellulose ether, white or yellow powder, non-toxic, tasteless, it can be dissolved in water, has good heat stability and salt resistance, antibacterial. The slurry fluid prepared by this product has good water loss, inhibition and high temperature resistance. Widely used in oil drilling, especially salt water Wells and offshore oil drilling.
Oil Drilling grade CMC products are divided into high viscosity (HV) and low viscosity (LV) categories, which are high-tech products with independent intellectual property rights of the company. It belongs to anionic cellulose ether, and has the characteristics of high purity, high degree of substitution and uniform distribution of substitution gao. It can be used as thickening agent, rheological regulator, water loss reducer, etc. CMC with high viscosity and low viscosity has excellent filtration loss reduction function in both fresh and sea water mud, and is an indispensable product in mud compatibility. CMC produced by our company is a highly purified product with white flowing powder in appearance and transparent viscous liquid in aqueous solution.
