摘要
截至2008年年底,我国已建油气管道的总长度约为6.4万千米,其中天然气管道3.2万千米,原油管道1.9万千米,成品油管道1.3万千米。2008年建设的重点管道工程有川气东送、西气东输二线等天然气管道,曹妃甸-天津等原油管道,兰郑长、郑州-安阳汤阴、长岭-株洲等成品油管道。目前,在我国的川渝、环渤海及长三角地区已经形成了比较完善的区域性天然气管网,中南地区、珠三角地区也基本形成了区域管网主体框架。我国油气管道运输仍存在一些问题:天然气管道输送能力不足,同时,地下储气库等调峰设施建设滞后,致使管道输送能力不能充分利用;部分原油管道老化,管线运能不足,管道设施不能满足陆上原油进口的要求;成品油管道建设滞后,管道运输技术与国外先进水平相比仍存在一定差距。未来几年仍将是我国油气管道建设的高峰期,管道在技术水平不断提升的同时,将继续向着高压力、大规模、大口径、高钢级方向发展。管道管理模式将从"建管合一"发展到"建管分离",并将积极建立管道完整性管理系统,从而做到对各种事故事前预控。
By the end of 2008 China had laid 64,000 kilometers of oil & gas pipeline, with around 32,000, 19,000 and 13,000 kilometers devoted to natural gas, crude oil and refined oil transmission respectively. Key pipeline projects in 2008 include natural gas pipelines such as the Sichuan-to-East Gas Transmission Pipeline and the 2nd West- East Gas Pipeline, crude oil pipelines such as Caofeidian-Tianjin, and refined oil pipelines such as Lanzhengchang, Zhengzhou-Anyang Tangying, and Changling-Zhuzhou. Relatively comprehensive regional natural gas pipeline networks have been laid in Sichuan & Chongqing, the Bohai Basin and the Yangtze River Delta area, and the backbone for regional pipeline networks has basically been laid in the Mid-South and Pearl River Delta areas. Nevertheless, there remain a number of problems with China’s oil & gas pipelines: natural gas pipeline capacity is inadequate, and the lag in construction of peak- adjustment facilities including underground gas storage prevents gas pipelines from taking full advantage of transportation opportunities; due in part to aging pipes, crude oil pipelines lack capacity and fail to meet requirements for overland crude oil import; construction of oil- product pipelines has lagged behind, as has China’s pipeline transporttechnology behind more advanced levels abroad. The next few years will be the peak period in China for constructing oil & gas pipelines, with continually upgraded technology, higher pressure, larger scale, bigger diameter and higher grade steel. Pipeline management will evolve from 'integrated construction & management' to 'separated construction & management', and a control system will be implemented insuring integrity of the pipeline system and avoidance of accidents, not just response to them.
