A Design Summary of Shen-Niu Pipeline for Crude 0il of High Pour Point

  • 摘要: 针对我国高减原的特点及管输沿线的地貌、地带气象条件。分析其特珠的流变性,认为高凝原油的输送温度必须高于凝国点,设计上提出以下技术措施确保安全输送。①各站设置水套加热炉。管道保温采用聚氨酯泡沫外加黄夹克,高压热稀油循环等②进用高强度钢管及对钢管的强度、热应力及稳定性的核算: ③在站内流动运行过程中各阶段的防凝和停运再启动,各设备的防凝保温等;④施工中的特殊要求, 试压后的清管预热及投油试运等。投产运行表明:设计所采取措施得当,施工达到了设计要求突破了高凝原油输送的技术难关,取得了较高的经济效益,为今后大规模开发高凝原油提供了实践依据。

     

    Abstract: In consideration of the characteristics of our high pour point crude oil and the terrain, meterological conditions along the pipelines, it is assumed through analiysis of special rheological properties that the transporting temperature must be higher than the pour point. To garantee safe transportation there should be taken the following technical measures: 1. To install water jacket furnaces in pump stations, and to have pipelines insulated with yellow jacketed polyurethane and hot thin oil circulated at high pressure, etc, 2. To select steel pipes of high strength and make accounting of the properties of steel pipes such as strength, heat stress and stability; 3. To prevent solidification of oil at varied phases passing through a station and to have all apparatus insulated to keep them from soldification; 4. To meet special requirement in construction, do pipeline clearing and preheating after pressure test and trial operation。The commisioning operation shows. The measures taken in design are proper, and construction meet the requirement of the design. the technical hard nut in tran-sporting high pour point crude oil is broken with considerable economic efficiency, providing practical basis for developing such kind of crude oil on a large scale.
