Anionic polyacrylamide used for EOR(Enhanced Oil Recovery)
Chinafloc A2320 is a specifal size of anionic polyacrylamie with high molecular weight used for
EOR(Enhanced Oil Recovery)
1. Product characteristics
This product is a trpe of ultra-high molecular polyacrylamide specifically produced for oilfield polymer flooding
process(EOR)by adopting a new technology.highest molecular weight goes uo tp 25million,moderate hydrolysis,
high viscosity and fine solubility.
Oilfield displacement agent.when the oilfield comes into tertiary recovery period,single waterflooding oil
displacement method,since its flow rate is higher than that of the underground crude oil it drives,will greatly reduce
its spreading efficiency and increase water consumption,and greatly increase the water content of the crude oil
collected.in addition,nonuniformity of oil pool’s geology will also reduce the spreading efficiency.for special oil
layer of positive rhythm deposition.upper thick and lower thin,lower part permeability higher than the upper part.
when displacing oil by single waterflooding,it usually spreads along the bottom,while leaving large amount of
crude oil in the upper part the oil layer undisplaced,using polyacrylamide which can increase the viscosity of water
in stead of single waterflooding will help to improve the spreading efficiency and reduce water content of crude oil,
increase oil production.our company’s partial hydrolysis polyacrylamide fully meets up with requirements of
oilfield’s tertiary recovery(EOR)users can select to use according to different characters of different oilfield such as
formation temperature,mineralization,viscosity of polymer solution injected and etc.
The product is moisture absorbent, thus to protect from damp and moist for conservation. It should be stored in a
dry and ventilate storehouse, and not be exposed to air and sunshine.
25 Kg paper plastic three-in-one compound woven bags, or according to users’ requirement;
Its shelf life is 2 years.
