Embodiment 1
[0040] In an exemplary embodiment of the present invention, reference is made to figure 1 As shown, a method for calculating liquid phase thermal properties of marine heavy oil includes the following steps:
[0041] Calculate its thermophysical properties by replacing heavy oil with two components, the two components include a first virtual component and a second virtual component, wherein the first virtual component is pure hydrocarbons with low carbon number;
[0042] Calculate the average density and average kinematic viscosity of the heavy oil in the critical temperature range according to the known basic thermal properties of the heavy oil, and calculate the average kinematic viscosity of the heavy oil according to the average density and average kinematic viscosity;
[0043] Calculate the kinematic viscosity of the second virtual component at the first temperature and the second temperature according to the known thermal properties of the first virtual component and the ...
