Our anionic polyacrylamide is manufactured with ultra high molecular weight specially for EOR(Enhanced Oil Recovery) in oil field under new high-tech technology.
Application
This process has been used for several years in assisting oil field to increase the efficiency of oil recovery. By the addition of one ton of polymer typically 150 tons of crude oil can be gained therefore providing great benefits to the user. By introducing viscous polymer solutions to the flood the efficiency of the volumetric sweep is increased, channeling and breakthrough is decreased thereby having the overall effect of increasing the oil recovered.
Our polymer suits many different conditions experienced by oilfield operators in polymer flooding so that no matter what the temperature, saline conditions, permeability or oil viscosity are, we have the correct product for the application. The standard products can be either directly injected into the oil stratum or alternatively can be combined with a cross-linking agent and then injected into the oil stratum. These products can be used at oilfields with an oil stratum temperature lower than 60°C and total dissolved solids (TDS) lower than 6,000ppm.

Polymer Mixing
To obtain homogeneous solution, efficient dispersion is necessary. The most convenient method of dispersing these products is with a polymer eductor or a commercially available dry powder feeder unit. Solution should be made up at 0.1-0.3% solid. Make-up water temperature should be between 10℃ and 40℃ for optimum product performance.
Following dispersion into agitated water, stirring should continue for about an hour to ensure complete dissolution. Stirring maybe carried out by propeller type stirrer with a speed of 200-500 rpm.
It is recommended to have both a stock make-up tank and a solution holding tank for dosage into the system.
The above recommended anionic solution concentration are stable for up to one week.
Aluminum, zinc, copper, or iron should be avoided in make-up system.
Shipping, Handling and storage
PHPA is packed in 25kg Kraft paper bag with inner plastic bag.
Store in cool room.
Do not contact air directly for long time, the product can absorb damp to become agglomeration and difficult for dissolving.
The shelf life is two years
Health and Safety
PHPA is not dangerous chemicals, please read MSDS for detailed information. The product will be very slippy on ground after contacting water, any spill of product should be cleaned with water completely. |
