Measurement of the specific heat of waxy oil

The measurement was made of the relationship between specific heat and temperature of the crude oil in Da Ching and Sheng Li fields by using self made a device. Based on test data it makes an analysis of the impact of the wax potential heat and precipitation upon specific heat, presents experience equations in relation to three temperature ranges, and comments on the impact of the relationship between specific heat and temperature upon the technological calculation of pipeline temperature drop, general heat transmission coefficient, normal temperature trasportation, etc.
