Performance Indicators of Anionic-polyacrylamide

Main Application

Oil-displacing agent of oil field tertiary oil recovery:

It can adjust the rheology of filled water, increase the viscosity of driving liquid, improve water

drive wave and efficiency, lower water phase permeability in ground layer, and enable water and

oil to flow forward at even speed. Its effect is that it is mainly used in tertiary oil recovery of oil

fields in the aspect oil production, and raw oil of about 100 to 150ton more can be produced through

filling the macromolecule polyacrylamide product one ton.

Well drilling mud raw materials:

in oil field exploration and development and exploration of geology, water and coal, it is used as

adhesive of well drilling mud raw materials, can improve the service life of drill bits, improve the

drill speed and drilling footage, and reduce plug in replacing drill, and has prominent well slough

preventing effect, and it can be used as fracturing fluid of oil fields or plugging agent of controlling

profile and plugging water.

Functions:

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

roleof enhancing the stability of borehole .
