摘要: 为探究不同淤积物沉积因素对原油沉积的影响,采用单一变量法,控制不同温度区间、剪切速率、驱油剂含量、沥青质含量等影响因素,利用室内储罐进行淤积物沉积对比实验。结果表明:当油壁温差不变且温度区间逐渐上升时,淤积物沉积量逐渐减小;当转速低于90 r/min时,随着转速增加,淤积物沉积量增加;当转速高于90 r/min时,随着转速增加,淤积物质量逐渐减少;淤积物的质量在驱油剂含量0.5%~1.4%区间内增加了13.9%;沥青质含量与淤积物质量呈非线性关系,当沥青质含量达到4.0%~4.5%(w,%)时,淤积物质量减少。分析结果可为未来摸索储罐淤积物沉积规律提供借鉴。

Abstract: In order to explore the effects of different deposits sedimentation factors on crude oil sedimentation, a single variable method is used to control the factors such as different temperature ranges, shear rate, oil-displacing agent content and asphalt content. Indoor storage tanks are used to carry out deposits sedimentation comparison experiments. The results show that when the temperature difference of the oil wall is constant and the temperature interval increases gradually, the sedimentation of deposits decreases gradually; when the rotating speed is below 90 r/min, the sedimentation of deposits increases as the speed increases and when the rotating speed is higher than 90 r/min, the deposit sedimentation mass decreases gradually with the increase of the speed; the deposit mass increased by 13.9% in the range of 0.5% to 1.4% of the oil-displacing agent content. There is a nonlinear relationship between asphalt content and deposit mass, and when the asphalt content reaches 4% to 4.5% (w,%), the deposit mass decreases. The results of the analysis can provide reference for the sedimentation law of storage tank deposit in the future.
