anionic polyacrylamide used for oil drilling and bored pile

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, this product can improve the lubricity and stability of the mud to reduce

the water loss, prevent sticking effectively, increase drilling efficiency.

Blocking Agent

The product 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

The product 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.
