Abstract: In the paper, six kinds of crude oil from different oil wells in Jianghan oil field have chosen and determined their condensation point, viscosity, wax precipitation point and wax content. The experimental results show that the average condensation point of the crude oil is 27℃, the crude oil's viscosity is low at temperature 50℃ and the average value is 33. 3mPa·s, wax contents of the crude oil are all above 10% and the crude oil is belong to high wax content oil. All above provide effective theoretical reference to the production, transportation and processing of crude oil in Jianghan oil field.
