Abstract
Petroleum samples from two holes of the Verkhne-Salatskoye deposit (the holes Nos. 118 and 122) have been studied. It has been found that they differ essentially both in their content of pitchy and aromatic components and in the composition of paraffin-naphthene hydrocarbons, which defines the features of their deposit formation. Accordingly, the process of sludge formation for a petroleum sample from the hole No. 122 that is characterized by a higher than usual content of pitchy components starts at a temperature of 50 oC. The process of deposit formation for a petroleum sample from the hole No. 118 occurs at 70 oC.
A decrease in the temperature of a petroleum flow leads to the predominantly dendritic type crystallization of paraffin hydrocarbons and to an increase in the structural amorphism of the petroleum deposit.
