摘要
含蜡原油在开采和管输过程中由于环境温度的降低会沉积在井壁和管壁上,减小了管道的有效流通截面,降低管道的输送能力,甚至会造成管道堵塞事故。综述了国内外学者对于石油管线蜡沉积的试验研究进展,分析了不同蜡沉积装置的工作原理、特点和适用范围,并提出了一些研究建议。
Waxy crude oil will precipitate and adhere to shaft wall and pipe wall in oil production and transportation because of reduction of the environment temperature,decreasing the effective inside diameter of the pipeline,reducing the transportation capacity of the pipeline and even causing pipeline blockage.Review was made of progress of experimental research on wax deposition in petroleum pipeline,principles,features and applicability of different wax deposition apparatus
