Properties and Applications of Polyacrylamide (PAM)
Moreover, Oilfield Polyacrylamide plays a pivotal role in fluid loss control during drilling and cementing operations. By forming a thin, impermeable layer on the formation face, it mitigates fluid loss into the formation, safeguarding wellbore integrity and preventing costly setbacks.

Sodium sulfonated asphalt is widely used as an additive in drilling fluids for oil and gas wells. It acts as a surfactant and helps to lessen the surface pressure of the drilling fluid. This property helps in the efficient movement of the fluid through the wellbore and helps to avoid the buildup of gas and other contaminants.

Get PriceWhat is the use of polyacrylamide in oil drilling?
For oil drilling, liquid or powder partially-hydrolyzed polyacrylamide is used as additives to water based drilling mud to provide a lubricating film and reduce friction at the drill bit, impart stability to shale and clay and increase viscosity [ 1, 22, 26 ].
How polyacrylamide (PAM) is used in sewage treatment?
In sewage treatment, using polyacrylamide (PAM) can increase the recycling rate of water reuse. In petroleum extraction, polyacrylamide (PAM) is mainly used in drilling mud materials and for enhancing oil recovery, widely applied in drilling, well completion, cementing, fracturing, enhanced recovery, and other oil field extraction operations.
What is polyacrylamide used for?
Polyacrylamide (PAM) is a collective term for polymers obtained by the homopolymerization or copolymerization of acrylamide monomers under the action of an initiator. It can be used as a coagulant, retention aid, sludge dewatering agent, and flocculant sedimentation agent, among other uses, and has a wide range of applications.
What is polyacrylamide (PAM) used for?
In raw water treatment, polyacrylamide (PAM) is used together with activated carbon for the coagulation and clarification of suspended particles in domestic water; in sewage treatment, polyacrylamide (PAM) can be used for sludge dewatering; in industrial water treatment, polyacrylamide (PAM) is primarily used as a formula agent.
How does polyacrylamide (PAM) reduce drag?
Polyacrylamide (PAM) can effectively reduce the frictional resistance of fluids, and adding a small amount of polyacrylamide (PAM) to water can reduce drag by 50-80%. Polyacrylamide (PAM) has thickening effects under both neutral and acidic conditions, and when the pH value is above 10, polyacrylamide (PAM) is easily hydrolyzed.
Does polyacrylamide thicken?
Polyacrylamide (PAM) has thickening effects under both neutral and acidic conditions, and when the pH value is above 10, polyacrylamide (PAM) is easily hydrolyzed. When presenting a semi-network structure, thickening becomes more apparent.
