Resumo

The physicochemical properties of crude oils (density, viscosity, asphaltene concentrations) from the Bach Ho oilfield (Vietnam) have been correlated with 1H NMR relaxation parameters (spin–lattice and spin–spin relaxation times T1i and T2i, respectively), and their temperature dependence has been studied. The results are discussed in terms of the concept of the formation of structural units (SU) in oils. The standard “alkane line”—the conventional correlation ηТ1,2 = const/Т for viscous oils—has been refined. The temperature dependences of T1,2i have been obtained, which manifest ordering processes in the test oils.
