摘　　要：针对输气管道末段储气设计存在的问题,在末段储气能力计算式基础上,推导证明任一管径和工况下管道末段都具有最大储气能力,以及末段储气能力曲线具有对称性。分析了最优储气能力与末段尺寸的关联性,提出末段长度可调范围的概念,给定了临界末段长度的计算区间以及该长度的计算方法。认为增大末段管径是提高末段储气能力的一个好方法;当末段储气能力满足设计要求时,可在末段长度可调范围内选择符合现场需要的末段长度,减少管道末段站间距调整的盲目性。In order to solve the problems in designing end section of a gas transmission pipeline, storage capacity curve of end section was proved to have symmetry with a maximum value under arbitrary diameter and operating conditions, by deducing based on storage capacity equation of end section. The relationship between optimum storage capacity and end section size was analyzed. The concept of adjustable range of end section was presented, and Computation interval of critical length of end section and calculation meth- od for the critical length were given. It is believed that enlarging pipe diameter is a good choice to improve storage capacity of end section. Also, if the storage capacity is sufficient to design requirements, the end section length can be found in the adjustable range of end section to meet engineering requirement and reduce the blindness of adjusting the end section length.
