Enhanced oil recovery (EOR) is crucial in the oil extraction process. As the oil reservoir is exploited, the oil content will gradually decrease, so the method of enhancing the recovery rate has become the focus of research. Polyacrylamide (PAM) is an important chemical agent widely used in tertiary oil recovery. This article will deeply discuss how PAM improves oil recovery.

Polyacrylamide (PAM) is a high-molecular organic compound with excellent hydrolyzability and high molecular weight. In tertiary oil recovery, PAM is adsorbed on the rock surface to reduce the flow resistance of oil-water fluid, thereby enhancing oil recovery.

The application of PAM in tertiary oil recovery is mainly divided into the following steps: first, inject the PAM solution into the reservoir to make it adsorb on the rock surface; second, control the adsorption of PAM on the rock surface by adjusting the injection speed and pressure Finally, the crude oil is stripped from the rock surface through physical methods, so as to achieve the goal of enhanced oil recovery.

Experimental data shows that the use of PAM can increase oil recovery by 10%-20%. In addition, compared with traditional tertiary oil recovery methods such as alkaline water flooding and surfactant flooding, the use of PAM can not only significantly increase the recovery rate, but also have less impact on the environment.

It is evident that polyacrylamide (PAM) plays an important role in enhanced oil recovery (EOR). By adsorbing on the rock surface and reducing the flow resistance of oil-water fluids, PAM significantly improves oil recovery. In the future, with the improvement of environmental protection awareness and technological progress, the application prospect of polyacrylamide in tertiary oil recovery will be broader.
