Description

technical field [0001] The invention relates to a test bench and method for testing the temperature characteristics of a high-viscosity fluid. Background technique [0002] Crude oil or petroleum processing products (such as: chemical raw materials, lubricants, paraffin, asphalt, etc.) usually exhibit high viscosity, which leads to high pipeline resistance and poor flow performance of such fluids during pipeline transfer. At the same time, this type of fluid generally has obvious viscosity-temperature characteristics, that is, the temperature increases, the viscosity of the fluid decreases, and the fluidity becomes better. [0003] However, most of the current studies on the temperature characteristics of high-viscosity fluids are qualitative analysis, and there is a lack of quantitative research. Viscosity-temperature characteristics cannot achieve better field application results. For example, when heavy crude oil is transported through pipelines, it is often necessary t...

Problems solved by technology

However, there is no corresponding test device and method for the current research on this aspect, and the research is also limited to qualitative analysis.

In addition, during the heating process of high-viscosity fluid, the heat exchange efficiency is low, and the phenomenon of long heating time and uneven heating often occurs, which makes it difficult to accurately evaluate the fluid flow, and the experimental error is relatively large
