CHINAFLOC

~Temperature Tolerant and salt resistant PAM
 

1. Product characteristics
It is designed for the use of wastewater of oilfield’s tertiary recovery which is to make the recycling use of the wastewater recovered and to benefit the environment. It is a polymer used to solve the problems of the high salt and high temperature in the tertiary recovery of the oilfield blocks. It is developed to maintain the ternary system’s high viscosity value in tertiary combination flooding.

3. Application
It could be used as the oilfield displacement agent for high temperarture and hypersalinity formation. Most of the oil reservoirs in China are of high temperature and hypersalinity formation which the temperature is usually over 70 degree while the mineralization degree is generally over 4000ppm. This PAM we designed can stand the temperature over 85 degree with the salt 20000ppm, it is fully in compliance with requirements for oil recovery in the high temperature and hypersalinity formation.

4. Product package
25 Kg paper plastic three-in-one compound woven bags, or according to users’ 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 in a dry and ventilate storehouse, and not be exposed to air and sunshine.
