Аннотация

The structural properties of asphaltenes, especially related to the dynamics of their aggregation, have been investigated by different experimental and theoretical methods during the last decades. However, there are only few works devoted to study the dynamics of asphaltenes in native hydrocarbon environment. In this report we illustrate a possibility to use electron paramagnetic resonance (EPR) spectra of vanadyl porphyrins in asphaltenes for the qualitative and quantitative analysis of their rotational mobility in crude oil samples. Based on the simulation of the EPR spectra, a simple semi-empirical parameter sensitive to the transition between motional regimes is proposed. This mobility parameter can be potentially useful for the prediction and analysis of thermal influence on heavy oil reservoirs during the petroleum-production. It is found that the rotational correlation time of the complexes in heavy oil samples changes discontinuously with temperature. The observed jump could be
