摘要
依据流体在管道内的流动规律,论述了油气管道的减阻增输机理。针对油气管输存在流动摩阻大、输送量适应范围小等问题,考察并探讨了改善输油管道输送性能的相关技术。通过减小管输流体的动力粘度、降低湍流的附加应力,可以显著减小管输摩阻,降低管输能耗,提高管道运行的弹性和效率,保障管道安全经济运行的同时获得减阻增输效果。针对石油管道系统,分析了各种减阻增输技术的应用效果和适用条件,提出了一些具有应用前景的新方法。
Drag reduction and throughput increase mechanism for oil and gas pipelines are described based on flow law of fluid in pipeline. In allusion to the issues about large frictional drag of flow and narrow suitable transportation scape of throughput existed in oil and gas pipelining, relative technologies to improve transportability of oil and gas pipelines are investigated and discussed.It is considered that frictional drag and energy consumption of pipeline can be remarkably decreased by means of reducing dynamical viscosity of fluid and additional stress of turbulance, which can raise operating flexibility and transportability of pipelines and ensure safe and economic running of pipelines for drag reduction and throughput increase. On account of oil pipeline system,application effectiveness of different drag reduction and throughput increase techniques as well as their suitable scopes are analyzed, and some new techniques with application prospect are put forward.
