tertiary oil recovery chemicals

Anionic polyacrylamide :
1.Suitable temperature(degree Celsius):65-85
2.Suitable salinity mg/l:8020-32868
1. Product characteristics
the ca series of Polyacrylamide for Oil displacement is developed as the special product of tertiary oil recovery based on the characteristics of oil-displacement mechanism and oil reservoir via the special design of molecule. The product has the characteristics of good heat resistance, salt tolerance viscosity and anti-shearing, etc., which enables to effectively increase the viscosity of displacing fluid in oil reservoir, and also increase the wave and its coefficient, thus to improve the recovery ratio of petroleum.

3. Application
It can be used for tertiary recovery auxiliary agent, which can used alone or combined with alkaline surface active agent to constitute binary or ternary combination flooding.
According to different reservoir conditions such as reservoir temperature and salinity, the company can provide the relevant products.
4. Product package
The product is packaged with paper plastic three-in-one compound woven bags, and 25 Kg in each bag or determination in accord with the user’s requirement. Its shelf life is 2 years.
5. Attention
The product is moisture absorbent, thus to protect from damp and moist for conservation. It should be stored at a dry and ventilate storehouse, and not be exposed to air and sunshine.
