西部管道是我国目前输送距离最长、设计输量最大、设计压力最高、输油工艺先进、自动化水平高、多支线分输和注入的复杂的原油成品油双管同沟敷设管道。本文从西部同沟敷设管道输油工艺、管间距以及原油成品油管间热力影响因素、建设施工工艺和管道沿线的阴极保护防腐技术等多方面,对西部原油成品油同沟敷设管道进行了研究。
The western pipeline is the complicated pipeline of crude oil product pipelines with the same transportation distance, the largest designed transmission volume, the highest design pressure, advanced oil delivery technology, high automation level, multi-branch transmission and injection. In this paper, pipeline laying technology in the western part of China is studied from the aspects of pipelines laying in the same trench in the west, pipe spacing and the thermal influence factors of crude oil products pipes, construction technology and cathodic protection anticorrosive technologies along the pipelines.
