China best sales chemical anionic polyacrylamide for ehanced oil recovery（EOR）

Product characteristics

Anionic polyacrylamide is a kind of White or yellow powder,non-toxic,non-corrosive,easily solubale in water,mainly used as a selective flocculant for non-dispersed,low solid phase water-based drilling fluid.it can help to reduce water losses,improve drilling fluid rheological properities and reduce the friction resistance as well.

Product Application

Flocculant
The polarity gene adsorbs the solid particles dispersed in water, bridges between the particles and formats the large aggregates, sedimentation and separates of water, flocculates detritus and clay in drilling fluid.

Dispersant
In the drilling mud treatment,aniopnic polyacrylamide can improve the lubricity and stability of the mud to reduce the water loss, prevent sticking effectively, increase drilling efficiency.

Blocking Agent
Anionic polyacrylamide  can generate cross linking under the effect of Al3+, Fe 3+, Ca2+ and other ions, a part of high molecular compound is changed from linear shape into body shapes. The product is not water-soluble, and can be adsorbed on the borehole to block ground layer gaps and to prevent the leakage of drilling fluid.

Lubricant
Anionic polyacrylamide can be absorbed on the surface of metal or clay particles to form liquid film to change friction on the solid surface into liquid frication, thereby lubricating drill bits and drills, lowering the mud cake frication coefficient, and reducing underground accidents.

Fluid Loss Additive
The hydrolysis degree is higher, the hydration group on the molecular chain is more, the hydration is better, and it changes from flocculant into fluid loss additive. Drilling mud should be treated to keep cake’s permeability as low as possible in order to maintain a stable borehole and to minimize filtrate invasion, and damage to the pay zone.

Shale Inhibition Agent
The multi-point adsorption of polymer formats to the criss-cross membrane macromolecules, plays a role of enhancing the stability of borehole.
