Polyacrylamide contribution

Polyacrylamide is not only widely used in the petroleum industry, but also plays a significant role in various other fields. From industrial wastewater treatment to sewage purification, from textile sizing to papermaking, its applications are extensive. In oil exploration, polyacrylamide has become an essential component, particularly in drilling mud systems where it helps improve oil recovery rates. It enhances viscosity, reduces fluid loss, and improves the rheological properties of the drilling fluids, making it crucial for operations such as cementing, fracturing, and enhanced oil recovery. As China's oilfields enter the middle to late stages of development, efforts have been focused on increasing oil recovery through advanced techniques like polymer flooding and ternary composite flooding. By injecting aqueous solutions of polyacrylamide, the oil-water mobility ratio is improved, which leads to higher crude oil content in the produced fluids. While the use of polyacrylamide in oil fields is still limited in many foreign countries, Chinese oilfields such as Daqing and Shengli have started adopting polymer flooding technology extensively due to their unique geological conditions. Beyond the oil industry, polyacrylamide is also widely applied in environmental protection, agriculture, and even in the food industry. Its ability to absorb water and improve soil structure makes it valuable in agricultural applications. Additionally, it is used in filtration processes and as a flocculant in wastewater treatment. With its versatile properties, polyacrylamide continues to play a vital role in both industrial and environmental sectors. Http://news.chinawj.com.cn Submission:
