Polyacrylamide (PAM) plays a crucial role as both a viscosifier and
shale inhibitor in drilling fluids used in oil and gas operations:
1. Role as a Viscosifier
- Increases fluid viscosity: Polyacrylamide increases the viscosity of drilling fluids,
enhancing their ability to suspend and transport drill cuttings and
solids, preventing them from settling at the bottom of the well.
- Improves fluid stability: The long-chain structure of PAM improves the fluid’s consistency
and rheology, maintaining good flowability and stability under
varying temperature and pressure conditions.
- Reduces fluid loss: PAM helps reduce the loss of drilling fluid into surrounding
formations by decreasing the filtration rate, protecting the
formation and maintaining wellbore integrity.
2. Role as a Shale Inhibitor
- Prevents shale swelling and dispersion: Polyacrylamide interacts with clay minerals in shale formations,
inhibiting water absorption, which prevents the swelling and
disintegration of shale. This contributes to the stability of the
wellbore.
- Forms a protective film: PAM can create a thin film over shale surfaces, acting as a
physical barrier that reduces water penetration, thus protecting
the shale from erosion.
- Enhances wellbore stability: By controlling shale hydration and expansion, polyacrylamide
helps maintain the structural integrity of the wellbore, reducing
the risk of collapse and ensuring a smoother drilling operation.
Summary
As a viscosifier, polyacrylamide increases the suspension and
carrying capacity of drilling fluids, while as a shale inhibitor,
it minimizes water-induced shale swelling and maintains wellbore
stability, making it an essential additive in drilling operations.
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.
