High Viscosity PAC Oil Drilling salt resistance NA PAC LV ISO9001

PAC Oil Drilling CMC NA PAC-LV API-13A HIGH PURITY

Qingdao Linguang Biochemical Co., Ltd is a professional high-tech enterprise which was established in 2010.which is a branch company of Dongying Linguang New Material Co., Ltd. We engage in the development, manufacture, sales and service of sodium carboxymethyl cellulose(CMC).

The annual output of our company reaches 20KTon and we gained the certification of ISO9001 and ISO14001 in2012.

PAC and 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.


Special Function Products
*Granulation Products
Improve the work conditions, reduce the dust, dissolve fast and enhance the construction efficiency.
*Instant Products
It can be dispersed and dissolved quickly in water, and it is more convenient and simple when used in rugged drilling environment.
Higher efficiency in cement slurry configuration and low requirement for construction equipment.
*The products in Special Applications
When in the complicated conditions with small usage, the filtration reduction property is of more excellence .

Effect of CMC in oil field
Mud with CMC makes wall of a well thin and solid
Add CMC in mud to make drilling machine get low shearing force
Mud with CMC almost is not influenced by mould
Mud with CMC has fine stability

Advantages of Weiyi CMC in oilfield
