天然气长输管道末段压力变化研究

Research on Pressure Change in the Last Section of Long Distance Gas pipelines

阐述了长输管道末段的基本功能,并对长输管道末段的储气能力对管道末段长度以及压力变化的影响进行了论述,包括储气初期与储气终了末段管道压力变化、副管添加进行了研究,研究采用了建模计算、假设、迭代、校核等方法。

Basic functions of the last section in the long-distance gas pipelines were described, and effect of storage capacity in the last section on length and pressure change of the last section in the long-distance gas pipeline was investigated. The study used the methods of modeling calculation, assumption, iteration, checking and so on.
