Abstract:
Asphaltenes are the heaviest polar components in crude oil and have an important influence on the crystallization, gelation, and flow behavior of waxy crude oil. This article briefly introduced the discovery process of asphaltenes in crude oil and several existing description methods. According to the existing form and structure characteristics of asphaltenes in crude oil, the development, advantages, and disadvantages of asphaltenes colloid theory and practical solution theory, as well as the two-dimensional and three-dimensional structure models of asphaltenes were summarized. The mechanism and characteristics of asphaltene precipitation were discussed, and the research methods describing the kinetic process were summarized. Based on the analysis of the physical process of crude oil crystallization and gelation, the influence of asphaltene on the above process was also summarized.
