大型油气管道伴行间距的确定

随着我国石油天然气工业的迅速发展,油气管道工程的建设日益增多。在部分地区,由于受管道沿地形、交通等条件的制约,两条及以上的管道进行伴行敷设的情况将不可避免。通过对西部油管道、西气东输管道这两条目前我国最长伴行距离、最大管径、最高压力的油、气输送管道伴行间距的分析,提出了今后大型管道伴行距离确定的原则和思路。

Determination of Space between Large-size Companied Oil and Gas Pipelines

With rapid development in oil and gas industry,there are more and more pipeline construction projects in China.In some regions,due to such factors as terrain,traffic,etc.it is unavoidable that two or more oil or gas pipelines are laid in parallel.Analyzed are collateral distances and collateral spaces,the biggest diameters and the highest pressure of the western oil pipeline and the "West-to-East Gas Pipeline",which are the longest pipelines and have the longest collateral distance in China at present and principles are put forward for determining the collateral space between large-size pipelines in future.
