CMC Oil Drilling Grade CMC LV HV Saturated Salt Water

We are the professional high-tech enterprise which was established in 2010 and engage in producing CMC (Sodium carboxymethyl cellulose) and PAC (Poly anionic cellulose) in China. Output reaches 20000 metric tons per year.We take great pride in our product quality and have been working with top Clients for years. We are ISO9001,ISO14001, ISO22000 and HACCP,BRC,Halal and FSSC 22000 certified company.

CMC are used in oil drilling fluids and completion fluids. In drilling fluids, it works as viscosifier, flowing controller and filtration reducer, with strong suspending capability, high ability of carrying crumbs, and the function of cleaning drilling crumbs, stabilizing of well wall, preventing the mud from flowing away, protecting drilling bit and reducing the thickness of mud cake, but while in the completion fluids, it functions to control the fluid viscosity, suspend the heavy objects, bring the filler and avoid the fluids loss. It also can replace guar gum in fracturing fluids.

Application in Oil Drilling Fluids
*Non-dispersive System
Strong capability of carrying crumbs, restraining the dispersion of the clay, reducing the speed of pulp yield by clay, stabilizing the well wall and effectively increasing the drilling rate.
*Dispersive System
Good suspending capability, containing more solid phases, greatly increasing the stability of granule; best for configuring the high density drilling fluids, and adjusting the rheology of drilling fluids; forming the compact high quality mud cake in the drilling fluids. It has the good function of reducing the fluids loss and free water.
*Calcium treatment drilling fluids
Good ability of calcium resistance, preventing clay granule which caused by calcium ion from excessive flocculation and make the drilling fluids stay into the flocculation conditions and maintain its stable solid content and rheology, so that the drilling fluids have the good and stable performance accordingly.
*Salt water drilling fluids, sea water drilling fluids, and saturated brine drilling fluids
Low sensitive to salt, and strong ability resistance in salt, calcium and magnesium, and it worked as rheologic modifier. Fast adjust the drilling fluid rheology in the low dosage conditions. Meanwhile, it can fast carry out the drilling crumbs and maintain the lower solid content, and enhance the speed of the well drilling rate. Used as filtrate reducer will form the compact mud cake, and due to the filter liquor filtrated by filter cake is very close to the earth layer primitive water, so it is less damage to the oil and gas layer.
*Potassium Base Drilling Fluids
Low sensitive to sylvite, calcium salt and magnesium salt; fast and high efficiently adjust the rheology of drilling fluid. Besides the good effect in fluid loss reduction, it has the power of cleaning drilling crumbs and drilling bit, furthermore, it has the obvious effect in easily blocked drilling bit in earth layer.
*Polymer Drilling Fluids
Good compatibility with other polymer, strong suspending power, cleaning drilling crumbs fast and efficiently, making the drilling fluids stay into low solid phase and low dispersion of clay, and it is also the good filtration reducer.
*Low Solid Phase Drilling Fluids
Adjusting the rheology of drilling fluids fast and efficiently, excellent suspending power, cleaning drilling crumbs promptly and efficiently, maintaining the low solid content, enhancing the speed of the drilling rate, stabilizing the well wall, and possessing the good effect in filtration reducer.
*Environment Friendly Drilling Fluids
This products, with environment friendly, nontoxic, harmless and odorless, biodegradable property, cannot be rotten easily in service. Due to the low maintenance cost of drilling fluids, the constructors’ health and safety are guaranteed. It meets the demand of the kinds complicated geological conditions and no harm to agricultural production.
