摘要/Abstract

摘要： 蜡沉积研究中,油水两相蜡沉积的研究已成为研究重点,但对此领域的研究还处于起步阶段。本文系统阐述了国内外蜡沉积研究的发展现况,对近些年蜡沉积机理研究的新进展--剪切剥离以及老化机理作了分析。介绍了冷板、冷指实验装置和环道实验装置,对国内外学者进行的蜡沉积实验情况作了概述。介绍了国内外单相原油与油水两相蜡沉积动力学模型的研究现状,在单相模型基础上对Couto油水两相模型和Bruno改进模型进行了描述。今后的研究应以蜡沉积机理与预测模型为重点,分析油水两相流蜡沉积的影响因素,这对于缓解输油管道蜡沉积问题,增强管道输送能力具有现实意义。

Abstract: Paraffin deposition under different oil water conditions has become more and more significant in recent studies of wax deposition.However, research in the field of two phase deposition is still in its infancy.This study describes the current status of development of wax deposition studies at home and abroad.It also analyzes new progresses in recent years on wax deposition mechanism studies such as shear stripping and aging mechanisms.Cold plate device, cold finger apparatus and experimental loop have been introduced in this study and wax deposition experimental progresses made by domestic and foreign scholars are outlined.This study mainly introduces current research situation of dynamic model of single phase oil and oil water two phase wax deposition at home and abroad.Modifications based on the single phase Couto model and oil water two phase Bruno model are described.Future researches should focus on mechanisms and prediction model of wax deposition, analyzing the influence factors of wax deposition under different oil water conditions.That will make practical significance to relieve pipeline wax deposition problems and enhance pipeline capacity.

Key words: oil water two phase flow, wax deposition, deposition mechanism, dynamic model
