摘要
介绍了国内外原油降凝剂的发展概况,重点阐述了原油降凝剂的作用机理、结构特征、降凝效果的影响因素(包括原油组成、热处理温度、冷却速度、降凝剂加入量、剪切作用)等方面的研究进展,给出了国内现有降凝剂的种类和国内外降凝剂的现场应用实例。提出应加强原油降凝剂降凝机理、对用于原油降凝与降粘的不同化学剂间的相互影响作用以及原油降凝剂研究方向等问题的研究。
This paper hriefly introduces the progressive general situation of pour point depressant in the world. pressanl are mainly discussed,including the effect of the contents of paraffin;the temperature and quantity of pour point depressants; cooling velocity and shearing rate. The kinds of depressants and application in the oil field are listed. The current study fields are as following: the mechanism of depressants; the better depressants for Daqing crude oil and the influnce between different chemicals used in crude oil.
