Polyacrylamide application in oilfield chemistry

Polyacrylamide application in oilfield chemistry
Polyacrylamide, a versatile oil field chemistry treatment agent, is widely used in drilling, cementing, completion, maintenance, fracturing, acidizing, water injection, water plugging and profiling, tertiary recovery. It particularly benefits drill stimulation, water plugging, and tertiary oil recovery. The polyacrylamide aqueous solution offers high viscosity, efficient thickening, flocculation, rheology regulation, serving as an oil displacement and mud fluid regulator. In the mid to late stages of oil extraction, polymer flooding and triple composite flooding are primarily employed to enhance crude oil recovery rates through improving oil flow velocity and increasing oil content in produced fluids. Incorporating polyacrylamide into tertiary oil recovery enhances oil displacement capacity, prevents oil layer breakthroughs, and boosts oil bed yield.
