Особенности структурно-механических свойств нефтяных дисперсных систем
Abstract
dc:description.abstractThe present-day challenge of oil industry is gradual decrease of conventional light crude reserves and increased consumption of hard-to-recover heavy crude. The goal of thesis is to establish change regularities of structural-mechanical properties and thermody-namic activation parameters for viscous flow in oil dispersed systems (ODS) of various composition (paraffin and naph-thene and aromatic bases) from Timan-Pechora petroleum region (Russia) in a broad range of temperatures and shear rates and under the exposure of external fields, and also to experimentally determine phase diagrams of binary hydrocarbon systems (nonadecane – decaline and nonadecane – naphthalene) modeling ODS mixture of completely opposite nature. Study results can be used for predicting and preventing structure formation during production, transport and storage of ODS's with various content of solid paraffins, resins and asphaltenes.
