成品油管道试运投产流程

在条件具备的情况下,成品油管道试运投产包括站内设备单体试运和分系统试运、干线清扫、管道充水、全线输水联合试运、管道投油、油品分输作业（管道分输支线投产）等过程.描述了各个过程的目的、内容及实施步骤,给出了空管投油方式和油顶水投油方式的适用条件,介绍了多起伏、大落差成品油管道采用空管投油方式时在油头前建立背压的方法,同时指出多起伏成品油管道因其在低点处易形成稳定的油水混合物,宜采用油顶水投油方式投产.（参4）

Commissioning trial procedures of product oil pipeline

When conditions are ready, the commissioning trial of product oil pipeline will follow the order in commissioning the station equipment and subsystems, purging of trunk line, water filling of pipeline, overall commissioning of whole line with water, commissioning with oil, product offtake operation （commissioning of branch lines） and so on. The paper elaborates the aim, content and implementation procedures of each step, explains the applicable conditions of direct commissioning and oil-after-water commissioning, introduces different ways of establishing back pressure before the oil head when direct commissioning is used on product pipelines of big elevation, and points out that as stable oil water mixture is apt to form at the low spots of hill product pipeline, it is better to take the oil-after-water way to commission such pipeline. （4 References）
