Study of Polymeric Crude Oil Fluid Improver Crystallinity
The characteristic groups of polymer were analyzed by the IR spectrometrer. The crystallinity of different style wax crystal and the fluid improver additive(FIA) were measured by the X-ray diffraction analysis. The results showed crystallinity of wax crystal was close correlation with the polymer fluid improver and the change of wax crystal dispersibilty will be caused by the difference of crystallinity which make change of pour point depressing behaviour of the crude oil. At the same time found when crystallinity of the wax crystal was match with the additive the wax crystal dispersibilty and pour point depressing and viscosity depressing will change well that was proved by fluid behaviour improving at low temperature of crude oil system.
