摘要
在含蜡原油输送中，添加降凝剂可以有效地改善含蜡原油的低温流变性，是实现原油常温输送的有效途径之一，也是重要的原油输送安全保障技术之一。综合分析了国内外降凝剂的陆上和海上管道应用状况，探讨了锦州20-2油气田海底管道应用加剂输送技术的可行性，研究了降凝剂对锦州混合原油流变性的影响，论述了降凝剂的筛选、不加剂和加剂对原油凝点的影响及降凝剂改性效果的稳定性。研究结果表明，降凝剂使原油的凝点降低，原油的牛顿流体温度范围变宽，原油的稳定性良好。
Through adding pour point depressant to waxy crude oil, fluidity is improved effectively at low temperature. The application of PPD in the land and subsea pipeline at home and abroad is introduced, and feasibility on the application of PPD in JZ20-2 subsea pipeline is discussed in this paper. The test results show that PPD is able to depress the pour point, widen the range of temperature of Newton fluid, and improve the stability of crude. It is necessary to point out that transportation technology to add PPD whoul play a more important role.
