Application of Polyacrylamide In Oil and Gas field

Feb 28, 2024

Polyacrylamide (PAM for short) is a high molecular polymer that can be used as anionic, cationic or nonionic polymer. Here we are talking about anionic polyacrylamide.


Anionic polyacrylamide has a wide range of applications in the petroleum field, including the following aspects:


1. Oilfield flooding agent: Anionic polyacrylamide is widely used in oilfield water treatment and oilfield flooding processes. It can be used as a water treatment agent to help purify impurities and suspended solids in oil field water injection and re-injection water, improve water quality, and prevent sedimentation and blockage.


2. Improve crude oil recovery: In the process of driving crude oil recovery through water injection, anionic polyacrylamide can be used as a displacing agent to increase the interaction between water and crude oil and reduce the viscosity between crude oil and sediments. Adhesion, improve the fluidity of crude oil and increase crude oil recovery.


3. Prevent oil well clogging: During the oil well production process, anionic polyacrylamide can also be used as an anti-coalescing agent to prevent oil well clogging. Due to its high molecular weight and chemical properties, anionic polyacrylamide can change the force between water and solid particles, prevent the aggregation and deposition of solid particles, and reduce the occurrence of oil well blockage.


4. Auxiliary agent: Anionic polyacrylamide can also be used as an auxiliary agent for oil well cement conditioner to improve the fluidity and coagulability of cement slurry.


All in all, the application of anionic polyacrylamide in the petroleum field mainly involves oilfield water treatment, enhanced flooding agents, oil recovery improvement, blockage prevention and auxiliary agents. Its application helps improve the efficiency and reliability of oil production processes.
