The Fluid Resume of Crude Oil with PPD at Low Temperature after High Sheared

Through analyzing local and laboratory test results, this paper indicates that the fluid resume of crude oil with PPD is related to crude constitutes and temperature after high sheared: ①After high sheared, some crude oil fluidity destroyed can resume; some can not be destroyed; some can not resume; ②The fluid resume of crude oil with PPD is related to temperature, the fluidity destroyed by high sheared can resume at high temperature, but can not resume at low temperature.
