Polyacrylamide (PAM) plays a vital role in enhanced oil recovery
(EOR), particularly in polymer flooding, which is a tertiary oil recovery
technique. Here's a summary of its key functions:
1. Increase Water Viscosity
- Enhanced mobility control: Polyacrylamide increases the viscosity of the injected water,
which helps improve the mobility ratio between the water and oil.
This means the water can more effectively push the oil towards the
production well, reducing water fingering and bypassing.
- Better sweep efficiency: By thickening the water, PAM ensures a more uniform displacement
of oil across the reservoir, leading to improved sweep efficiency
and the recovery of more trapped oil.
2. Improve Reservoir Sweep Efficiency
- Reduces permeability in high-permeability zones: Polyacrylamide can preferentially reduce the water permeability
in the more permeable zones of the reservoir, forcing the injected
fluid into less permeable areas where residual oil might be
trapped.
- Minimizes channeling: In heterogeneous reservoirs, PAM helps reduce channeling effects,
ensuring the injected fluids don't just flow through the easiest
paths but instead push more oil out of hard-to-reach areas.
3. Stabilize Water-Oil Interface
- Improves oil displacement: The polymer flooding process stabilizes the water-oil interface,
reducing the tendency of the water to bypass the oil. This
increases the contact between water and oil, helping displace more
oil towards production wells.
4. Cost-Effective Oil Recovery
- Reduces water production: By improving sweep efficiency and reducing water breakthrough,
polyacrylamide helps in minimizing the amount of water produced
with oil, reducing the overall cost of oil production.
- Increases oil production in mature fields: Polymer flooding with PAM is particularly effective in mature oil
fields where primary and secondary recovery methods have left
significant amounts of residual oil.
Summary
In oil recovery flooding, polyacrylamide enhances the viscosity of
injected water, improves sweep efficiency, reduces permeability in
high-flow zones, and stabilizes the water-oil interface. These
functions collectively lead to increased oil recovery, particularly
in mature or heterogeneous reservoirs.
Product Description:
Polyacrylamide is an ideal chemical reagent for water treatment and
purification, palm oil processing, mining, papermaking, sludge
dewatering, and other industrial wastewater treatments.
Blufloc Anionic Polyacrylamide is a solid powder water-soluble
polymer with varying molecular weight and charge density. It is one
of the most widely used chemicals for water treatment purposes,
featuring special properties like thickening solution and
flocculation of small particles.
This synthetic chemical is highly customizable and can be tailored
to fit various applications, such as water purification, oil
processing, mining, papermaking, and dewatering of sludge. It helps
to remove impurities from the water and improve its quality,
allowing it to be reused for other purposes.
The advantages of using Blufloc Anionic Polyacrylamide in water treatment are numerous. It is highly efficient, easy to
apply, and doesn't leave any hazardous residue. Furthermore, the
versatile chemical is cost-effective and can be easily obtained
from most chemical manufacturers.
Features:
This type of coagulant proves to be economical to use as it
requires lower dosage levels. It is easily soluble in water and
quickly dissolves as it is noncorrosive and effective even with
lower amounts. This thereby eliminates the need for alum and
further ferric salts as primary coagulants resulting in a reduction
of the sludge in the dewatering process system.
