我国能源结构的改变与管道工业的发展

对世界经济发达国家近一个世纪能源结构变化的过程进行了回顾,并对世界和我国能源结构中主要能源的所占比例进行了比较。认为随着经济的发展,能源结构发生变化是一种必然的趋势,其中尤以石油、天然气逐步替代煤炭最具代表性。对我国能源结构的改变与管道工业的发展的关系做了阐述。针对输气管道建设,提出了投资风险分析、输送压力、管材等级与钢管、内外防腐层等9项重大技术课题,认为妥善解决这些课题,将对我国西气东输工程具有重要的战略性意义。

The Change of Energy Structure and Development of Pipeline Industry in China

In this paper,the author reviews the change process of energy structure in some developed countries within a century, compares the proportions of main energy covered in the energy structures in the world and China,and considers that with the development of economy,the change of energy structure is an inexorable trend,in which coal being substituted by petroleum and natural gas progressively is most representative. The author describes the relationship between the change of energy structure and development of pipeline industry in China,presents 9 technological subjects to be studied and researched in investment risk analysis,transportation pressure,pipe material grade and steel pipe,internal and external coating of pipe based on the pipeline construction in the West-east pipeline project,and considers that the research results will be strategic importance to the engineering.
