Stability of condensate oil mixed with heavy oil in Tahe oil field

摘要: 塔河油田外输重质油高含沥青质,与凝析油进行混掺输送过程中极易发生沥青质沉积,堵塞储罐及地面输送管线。在对油品胶体稳定性影响因素以及胶体稳定性理论认识的基础上,将塔河外输重质原油与凝析油按不同比例混合,通过斑点实验对混合样品进行相容性分析,给出定性结论,然后对混合原油稳定性参数进行测定,得到相容性量化数据,并确定2种原油相容时的合理配比范围,为有效解决不同油品掺混输送问题提供了理论指导。Abstract: Heavy oil of the Tahe oil field has a high viscosity, high density, high content of gum and asphalt. Asphaltene deposited frequently when heavy oil mixed with condensate oil, which blocks storage tanks and ground pipelines. In view of the influencing factors on the stability of oil colloid and combined with colloid stability theory, we mixed Tahe heavy crude oil and condensate oil in different proportions. The compatibility of mixed samples was analyzed using spot experiments, and some qualitative conclusions were made. Quantitative data have been obtained by the determination of mixed crude oil stability parameters. We determined a reasonable ratio range of the two kinds of crude oil, which provided theoretical guidance for effectively solving the problem of blending and transportation of different oils.
