任京输油管道加降凝剂正反输运行规律研究

Study on the Forward Transportation and Reverse Pumping Operation Law on PPD-benefited Oil in Renjing Oil Pipeline

摘要: 介绍了任京输油管道秋季加剂低输量现场试验, 通过逐步降低输量的方法, 监测管道运行参数, 以确定任京输油管道秋季加剂正反输允许的安全输量。研究了原油流变参数受正反输流程的影响程度和输量对原油输送温度变化的影响, 并系统研究了任京输油管道自恢复投产以来等效管径的变化趋势, 初步探讨了正反输管道的运行规律。

Abstract: The autumn low throughput experiment on PPD-benefited oil in Renjing Oil Pipeline is introduced, employing throughput reduced step and step, monitoring pipeline operation parameter, the acceptable safe throughput of RenJing Oil Pipeline is confirmed, and how the forward transportation and reverse pumping flow diagram affect oil rheological parameter is also researched. In addition, the influence of throughput on the oil transportation temperature is studied. The authors systemically investigate the variety trend of equivalent diameter of RenJing Oil Pipeline since it re-operation, preparatively discuss the forward transportation and reverse pumping operation law of RenJing Oil Pipeline.
