基于新型Couette结蜡装置的长庆原油结蜡特性及模型建立
Study on wax deposition of Changqing crude oil based on a newly developed Couette device
摘要
Abstract
In this paper, a systematic research on the law of wax deposition for Changqing crude oil under various experimen-tal conditions was carried out in an small Couette wax deposition device independently developed. FLUENT software was ap-plied to simulate the flow and temperature field of crude oil inside this new device to obtain the precise parameter values such as viscosity,temperature gradient,shear stress and so on. The results show that wax crystal solubility coefficient, temperature gradient and sheer stress at the wall plays a major role in the internal mechanism under different operating conditions, respec-tively. The simulation result agrees well with the distribution of the flow and temperature field in actual pipelines. The dy-namic model of wax deposition for Changqing crude oil was established with an average error of 6. 47%. Thus the feasibility of this new method was confirmed and could be used for the further research on wax deposition.关键词
