纳米降凝剂在含蜡原油管输中的应用

项目简介

含蜡原油是由石蜡、胶质、沥青质、芳香烃以及轻烃等组成的复杂混合体系,其中石蜡组分是影响含蜡原油流动性的主要因素。在较高温度下,石蜡溶解在液态原油中,具有较好的流动性;随着温度降低,蜡逐渐结晶析出,蜡晶间通过交联形成三维网络结构,原油胶凝而失去流动性。我国盛产含蜡原油(如图1中红色圆圈所示),尤其是东北管网的大庆原油,其含蜡量均在10%以上,属于高黏高凝的高含蜡原油,目前大都采用加热管道输送工艺。该工艺不仅要消耗大量的燃料油和动力,并带来环境污染,而且一旦管线停输,管线的再启动会存在极大的不安全性。

纳米降凝剂还有望实现国内其它长距离含蜡原油管道、海上管道、油田集输管道的间歇输送、降温输送、常温输送,包括胜利、长庆、辽河、中原等陆上油田和渤海、南海等海洋油田的含蜡原油。此外,该技术还可以在如苏丹、印度尼西亚、印度、委内瑞拉、美国等国家生产的含蜡原油输运中获得应用。

技术优势

与传统高分子降凝剂相比,纳米降凝剂的主要优势体现在以下几个方面:
