高蜡原油低温初始蜡沉积特性实验与模拟研究
Experimental and modeling investigation on initial wax deposition characteristics of highly waxy crude oil under low-temperature conditions
摘要
Abstract
In order to explore the wax deposition characteristics and mechanism of high waxy crude oil under low wall temperature conditions,this paper detailly investigated the initial wax deposition char-acteristics of high-waxy Changqing crude oil based on the self-developed Couette wax deposition exper-imental device.It is found that the initial gelation process is extremely fast compared to the traditional wax deposition process dominanted by the molecular diffusion mechanism.Moreover,the formed wax deposition has a homogeneous structure and its composition was consistent with the bulk oil.The ge-lation deposition process was analyzed from the aspect of heat transfer and crude oil gelation.A waxy crude oil gelation deposition model coupled with heat transfer and gelation mechanism was estab-lished.The accuracy of the model was verified through experiments(lower than 6.6%).This work will help further the understanding of wax deposition and improve the prediction accuracy of wax dep-osition.关键词
