- Abstract
The rheological behavior of crude oil is highly dependent on paraffin content, shear stress, shear rate, and temperature. To study the influences of these parameters on the rheology of the fluid, the flow curves for various paraffinic crude oils with 7 and 25 wt.% paraffin contents were generated using a digital rheometer of Anton Paar MCR 302 with a Parallel-plate diameter of 30 mm at a rotation torque of 100 nNm and the changes in the curves were tracked. In this regard, the shear-rotary tests were performed in a shear rate range of 100 to 600s-1 at 26 and 22oC. Since the Psaudoplastic fluid models are used to describe the non-Newtonian crude oils behaviors, by fitting the flow curves generated from the shear-rotary tests to the Power law model, the model indices for each of the paraffinic crude oils were successfully approximated.
