年输量不确定的油气管道优化设计

概述了国内外油气管道优化设计的概况和进展,针对以往的研究没有考虑油气管道年输量在实际运行后的不确定性,按照确定性输量设计的管道方案与实际运行存在很大差异的问题,认为应对各种优化设计技术和方法进行比较,以便从中选择适合于管道实际情况的设计方法,尽量减少设计方案与实际情况的差异,提高设计效率和投资效益.

The Optimum Design for Uncertainty Annual Transportation Capacity of Oil and Gas Pipeline

The pipeline transportation of oil and gas is the development direction of the oil and gas transmission in the future. The optimum design of the oil and gas pipelines is the key procedure of the pipeline construetion, which will realize the purpose of reducing the design time and saving the investment by adopting various optimizing technologies in the design. The research work of the optimum design towards the oil and gas pipelines has been conducted since the 50-60's in the 20 century abroad and has achieved much progress. However,compared the abroad, this work was set about much later in China and also acquires certain advancement by consulting the foreign equivalent. The previous research did not consider the uncertainty of pipelines'annual transportation capacity after their operation, and the pipeline scheme that follows the deterministic transportation capacity design differs tremendously from the actual operation. Consequently, during the design, the uncertainty of annual transportation capacity should be sufficiently taken into account so as to lessen the differences between the design scheme and the actual situation to the best.
