摘　　要：在西气东输二线管道工程东段施工中,由于工期紧迫导致某一段干燥不能按照常规工艺进行施工。为此根据空气干燥原理进行详细计算和分析,决定采用分段干燥、两端储气升压通气干燥的措施,不仅保证了干燥质量,而且有效解决了投产工期紧迫的问题。In the Second West to East Gas Pipeline construction,drying process for one section of the pipeline were not conducted if according to conventional process due to tight project schedule.Therefore the calculations based on air-drying principle are performed in detail and then the measure of sub-section drying with boosting storage gas pressure on both ends of the sub-section is taken.This method not only ensures drying quality,but also solves effectively the problem of tight project schedule.

关 键 词：长输管道 干空气 干燥质量 储气升压 缩短工期
