| Abstract: | Based on the structure characteristics of pour point depressants for crude oil, the depression mechanisms were studied systematically. It is believed that the depression mechanisms depend on the chemical structure of the depressants and the main influencing factors include the composition and quality of crude oil, molecular weight, colloid-pitch, etc. |
