长距离输油气管道的工作压力

工作压力是油气管道设计中的一个重要部分,它对管道的技术经济条件影响很大,如何确定它非常重要.列出世界上一些陆上油气管道的主要技术参数,进一步阐明了油气管道工作压力的特点,即输油管道工作压力决定着管道的建设投资;一般情况下,输油管道的工作压力不宜太高;输气管道的最佳工作压力与管道建设投资及输气经营费用有关;一般情况下,最佳工作压力趋向高值.

QU Shenyang : The Determination on the Operating Pressure of Oil and Gas Transportation Pipelines,OGST

The operating pressure of oil and gas transportation pipelines is a major part in design,which will impact on the tech-economic target and it is very important to determinate it.This paper lists the main technical parameters of land oil and gas pipelines in the world,further describes the characteristics of operating pressure of oil and gas pipelines,and considers that the operating pressure of pipeline is a decisive factor of construction cost of pipeline,and generally the operating pressure of oil pipeline is not too high,for the gas transmission pipeline,the optimum operating pressure is tending to high and is relative to the construction cost of pipeline and gas transmission managing cost.
