Correlation of Physicochemical Properties of Bach Ho Oils with Proton NMR Relaxation Parameters and Their Temperature Dependence
The physicochemical properties of crude oils (density, viscosity, asphaltene concentrations) from the Bach Ho oilfield (Vietnam) have been correlated with 1 H NMR relaxation parameters (spin–lattice and spin–spin relaxation times T 1 i and T 2 i , respectively), and their temperature dependence has...

Summary: | The physicochemical properties of crude oils (density, viscosity, asphaltene concentrations) from the Bach Ho oilfield (Vietnam) have been correlated with
1
H NMR relaxation parameters (spin–lattice and spin–spin relaxation times
T
1
i
and
T
2
i
, 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 η
Т

= const/
Т
for viscous oils—has been refined. The temperature dependences of
T

i
have been obtained, which manifest ordering processes in the test oils. |
