Abstract: With the continuous demand of energy, more and more light crude oil was consumed while conventional crude oil production decreased year by year. Therefore, heavy oil as the effective supplement of conventional crude oil was gradually concerned by people. And how to efficiently and economically transport super heavy oil attracted people's attention. A light oilblending and transportation process for super-heavy oil used by an oil field were characterized. By using a RS300 viscometer and other instruments, the dieselsuper heavy blend for the viscosity-temperature and rheological properties, solidifying temperature and stability were studied. The results show that the volume fraction of diesel up to 25%, diesel fuel blended with super heavy oil freezing point was low. And the blend had good fluidity, stability, as well as the process had good economical efficiency. When the volume fraction of diesel oil was further increased, the freezing point was not changed.
