Study on the Transient Flow Control of Long-distance Oil Pipeline

Taking Western Oil Pipeline as an example, the paper describes the reason of transient flow occurredin long-distanee oil pipeline and hazards to pipeline safety operation, and quantitative analysis on thestrength of transient flow is made.Pressure regulating and/or protection method to effectively control thetransient flow is provided by authors and pipeline operators conduct human intervention to remotely controlthe transient flow in pipeline it put forward.
