【 摘 要 】

In order to clarify the relations between the different initial states and safety of pipeline shutdown during the forward and reverse transportation process. Analyze the flow state and innovatively divide forward and reverse transportation process into 4 phase: forward cold oil control phase, forward hot oil control phase, reverse cold oil control phase, reverse hot oil control phase. Then, based on the analysis of the characteristics of pipeline temperature drop in different above phase, the safety of different initial state of pipeline shutdown is qualitatively analyzed from the view of oil temperature changes. Finally, define a new parameter “Safe Shutdown Probability ϕ'' to describe and quantitatively analyze the safety of different initial phase of pipeline shutdown during forward and reverse transportation. The analysis results show that the shutdown safety is lowest when ϕ=±0 and highest when ϕ=±1.
