In the restart process of pipeline containing waxy crude oil after shutdown, the rheological properties of oil, including viscosity, yield stress and thixotropy is studied. The entire restart process is decided by various factors; in this paper the effects of outlet temperature, shutdown and restart temperature as well as shutdown time duration to the rheological property are taken into the consideration. The measurements are employed using a controlled shearing rheometer to investigate rheological property based on different restart conditions. In addition, this paper has also researched affection of emulsion and blended samples mixing with two types of crude oil in various ratios. Finally comprehensive rheological evaluation to restartability is obtained.
