Abstract: The paper introduces the full rheological curve of waxy crude oil, which has an important position in the research of rheology for crude oil. It can explain the rheological behaviour of waxy crude oil in a comparatively perfected way and can reflect its rheological characteristics, thus haring an importance in the management of oil pipeline operation. In the paper, the rheological pattens have been studied and analized in several testing cases of specific crude oil. The author also suggests that the method and the standand for determining the full rheological curve of waxy crude oil should be established as soon es possible.
