APPF-1 Instant Soluble Polymer Flooding Agent


To overcome the exploration difficulties of thick reservoir, high permeability reservoir and high temperature & high salinity reservoir in heavy oilfield, and to apply conveniently for onsite mixing and injection without surface construction. Based on the emerging super-molecular chemical theory, very small portion of hydrophobic constitutional  unit is introduced into the backbone of conventional water-soluble polymer which will significantly enhance the properties of polymer thickening due to the self-assembly of macromolecular chain in water solution, especially in temperature resistance and salt tolerance. 

Application
Polymer flooding, Alkaline/Surfactant/Polymer(ASP) flooding and profile controlling.

Feature & advantages of APPF-1
  1. The APPF-1 is endowed with high thickening ability and salt tolerance owing to the hydrophobic association behaviours in the aqueous solution which will enhance the oil recovery especially for the high salinity reservoir in heavy oilfield.
  2. Good temperature resistance can be achieved since a kind of functional group to prevent the hydrolysis of polymer occurring is introduced into the polymer backbone via copolymerization. It makes the APPF-1 flooding fluid to be applicable to the high temperature reservoir.
  3. Instant soluble performance gives great conveniences to use existing water flooding equipment to run polymer flooding with a skid-mounted mixing unit, no need ground construction of mixing station.
  4. Diverse resource of water could be used for preparing APPF-1 flooding fluid including clean water, high hardness water and oilfield produced water with less loss of flooding effect.
  5. High Resistance Coefficient and high Residual Resistance Coefficient.
  6. Outstanding injection performance.

Usage
Recommended concentration: 0.1% - 0.3%
The APPF-1 can be directly prepared into the target solution with propose concentration, or it can be prepared into the mother solution and then be diluted.

Storage

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

Safety instructions

Avoid contact with skin and eyes.

If contact with skin, wash off with soap and plenty of water and consult a physician.

If contact with eye, rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
