Description
Technical field
The utility model belongs to the crude oil separation equipment, relate to a kind of viscous crude and special viscous crude [according to the regulation of People's Republic of China's China National Petroleum industry standard " heavy oil gathering and steam injection systematic design discipline " SY0027-94, temperature is in the time of 50 ℃, dynamic viscosity is greater than 0.4Pa.S, and temperature when being 20 ℃ density greater than 0.9161g/cm
3Crude oil be viscous crude; Temperature is in the time of 50 ℃, and dynamic viscosity is greater than 10Pa.S, and temperature when being 20 ℃ density greater than 1.0g/cm
3Crude oil be special viscous crude] with the gs-oil separator of its associated gas.
