This study centered on synthesizing polyamides derived from fatty acids and polyamines, which underwent further polymerization utilizing 1,2-dichloroethane as a vital crosslinking agent. The resultant compounds served as advanced flow enhancers, specifically engineered to investigate their impact on the pour point and viscosity of crude oil. These factors significantly impact the extraction, gathering, and transportation processes of crude oil. Notably, the integration of 1,2-dichloroethane cross-linked polyamide as a flow enhancer exhibited a remarkable effect in reducing the pour point of crude oil. Specifically, the introduction of 500 mg/L of PMA-5 and PMA-8 led to a decrease in the crude oil's pour point by 4.1 ℃, enhancing its fluidity. Furthermore, the application of 500 mg/L of PMA-1 resulted in a considerable reduction in viscosity, with a notable decrease rate of 29.2%. These promising findings have the potential to significantly improve the fluidity of crude oil, ultimately promoting energy conservation and minimizing the consumption of resources during its production and transportation cycles, thereby contributing to a more sustainable energy industry.
