Anionic Polyacrylamide Emulsion Used in Drilling Fluid Polymer and
Drilling Mud AdditivesAcid Fracturing EmulsionThis product has very good heat resistance and small change of
viscosity-temperature property below 120 ºC. Beside thickening, the acid compounded with thickening agent has
the advantages of below: - Easy to make on spot, low concerntration has good thickening
effect;
- Salt tolerance and heat resistance. The product is cationic
polymer, which could prevent the swell of clay and migration of
particle;
- Good drainage performance;
- Good compatility with other addtive like inhibiter, Fe stabilizer,
clean up additive and etc in the acidizing fluid;
- Reduce the acid rock reaction rate and acid loss rate, increase the
reaction radius of acid fluid.
How Does It Work in Drilling Fluids?
- Viscosity Control: Polyacrylamide helps to control the viscosity
(thickness) of drilling fluids. This is important because it
ensures that the drilling fluid can carry rock cuttings to the
surface efficiently.
- Stabilization: It stabilizes the drilling fluid by preventing the
formation of large clumps, keeping the fluid smooth and consistent.
- Water Loss Control: Polyacrylamide reduces water loss from the
drilling fluid into the surrounding rock formations, which helps
maintain the fluid’s properties and protects the wellbore.
- Shale Inhibition: It helps prevent the swelling and disintegration
of shale formations encountered during drilling, which can
otherwise cause problems like sticking of the drill pipe.
Benefits- Improved Drilling Efficiency: By stabilizing the drilling fluid,
polyacrylamide helps in more efficient drilling operations.
- Reduced Problems: It minimizes issues such as stuck pipes and
formation damage, leading to smoother and safer drilling.
- Cost-Effective: Using polyacrylamide can reduce overall drilling
costs by improving fluid performance and reducing downtime.

Fracturing fluidIn oil and gas field fracturing operation, polyacrylamide is used
as thickening agent for fracturing fluid to increase the viscosity
of the fracturing fluid, so that it can bring fracturing sand into
the fracture more effectively. And keep the fracture open to
increase oil and gas production. - Improve Oil Recovery: Polyacrylamide as a thickener can increase the viscosity of water
and oil. Improving the water-oil flow ratio, to form a
high-viscosity oil displacing agent. Promoting the flow of crude
oil in oil wells, so that more crude oil is driven out and the
recovery rate is increased.
- In tertiary oil recovery, one of the most widely used applications
is ultra-partially hydrolyzed high molecular weight polyacrylamide
(HPAM). High-viscosity polyacrylamide (HPAM) solution can improve
the oil driving efficiency and reduce the residual oil saturation.
High concentration of polyacrylamide can increase the recovery by
more than 20% on the basis of water drive, and overcome the defect
of alkali contamination to the formation.
- Water treatment: Wastewater generated in the process of oilfield mining (oily
wastewater) needs to be treated before discharge or reuse.
Polyacrylamide is widely used as a flocculant in oilfield
wastewater treatment. It can quickly settle suspended solids and
sediments in the water, reduce the clogging and siltation of oil
wells. And improve wastewater treatment efficiency and water
quality. Reducing the maintenance cost and cleaning cycle, and
extend the service life of oil wells. Oilfield sewage treatment,
polyacrylamide is an important class of synthetic organic polymer
flocculants. Compared with traditional inorganic flocculants,
polyacrylamide has the advantages of more varieties, high
flocculation efficiency and less sludge generation.
- Environmentally friendly: Compared with traditional chemicals, polyacrylamide degrades
faster, it doesn't bring persistent pollutants to the environment.
High-performance cationic polymer emulsion for acid fracturing,
offering heat resistance, salt tolerance, and improved oil
recovery. Reduces acid loss and clay swelling.
