由于西部油气资源具有分布广、油气井高度分散、生态环境脆弱、自净能力差等特征,生态环境破坏严重。该文通过对西部油气集输管道的建设、生产运行、失效过程的细节分析,提出了加强集输管道建设质量检验与控制,从管道建设初期抑制管道失效或损伤;提出在集输管道生产运行过程中加强巡检、实时监控从而更加有效及时地避免安全隐患以及油气泄漏事故的发生;提出通过集输管道安全事故"环境保护应急预案"的建立和完善,对失效事故所引起的环境污染源进行逐一排除,将失效所引发的环境污染降到最低。总结了集输管道服役期间沿线环境污染存在于集输管道建设、生产运行和发生失效等过程中环境保护措施,并对解决西部油气集输工程与环境可持续发展提出了可行性建议。 相似文献

Technology progress of oil & gas pipelines transportation project of CNPC since the 11th Five-Year Plan period
An introduction to oil & gas pipelines transportation project As a large industrious system, pipelines transportation industry is playing a more and more important role in oil and natural gas industry even in the world economy. Thanks to the efforts of 40 years, substantial progress has been achieved in the oil & gas pipelines construction in China. Till now, long distance oil & gas transportation trunk pipelines with large caliber have been completed one after another, with a total length exceeding 50 thousand kilometers (kin). CNPC boasts a long distance land oil transportation pipeline of 30 thousand km. 相似文献

China's pipeline industry has developed for 50 years till 2008. In the past 10 years, more than 50,000 kilometers of long-distance oil and gas pipelines have been constructed, of which gas pipelines reached about 30,000 kilometers, crude oil pipelines about 17,000 kilometers, and product oil pipelines about 7,000 kilometers. Oil and gas pipeline networks across regions have taken shape. Till then, China's pipeline industry has been ranked among the world's most advanced either in development speed or in technologies. China has developed a lot both in crude oil pipeline construction and in product oil pipeline construction in the whole year of 2007. 相似文献

油气管道并行敷设热力影响 总被引:1,自引:1,他引:0
对两条输油管道并行敷设的热力影响规律已有研究,但对输气管道和输油管道并行敷设热力影响情况尚未清楚。采用有限容积和有限差分相结合的数值模拟方法,对工程实际中可能存在的3种典型油气管道并行敷设方式(热油管道与输气管道低温段,冷输油管道或热油管道低温段与输气管道高温段以及热油管道与输气管道高温段并行敷设)的热力影响规律进行了研究。在这3种并行敷设方式下,分析得到了并行敷设的油气管道采用不同管间距时,沿线油温和气温相对于单管敷设的最大温差变化范围和热力分布特征。 相似文献
