• rheological model

The researches on the yielding behavior of waxy crude oil are still not systematic and thorough. Especially on yielding mechanism and criterion, most achievements are still on the qualitative stage. A rheological model with the dispersion parameter and hardening variable was proposed based on the mechanical analog and structure parameter. It can be used to describe the strain of waxy crude oil loaded by linear increased stress. According to eight groups of fitting results, the mean relative deviation ranges from 6.3% to 12.2%. The change of obtained model parameters with the test temperature conforms with the deformation mechanism of waxy structure.
