本文采用传统的管网分级优化技术,结合延川南煤层气田实际情况,合理优化约束条件,考虑地形起伏和集气规模等对整个管网系统布局方面的影响,优选传统的数学模型方法,建立了适合本区块煤层气集输管网优化的数学模型,并应用于对气田集输管网管径、壁厚等参数进行优化的设计中,达到了管网建设投资费用最省这一目的。
In this paper, the traditional pipe network grading optimization technology, combined with the actual situation of Yanchuannan coal-bed gas field, the rational optimization of constraints, taking into account the impact of topography fluctuations and the size of the gathering on the entire pipe network system layout, the traditional mathematical model optimization method, established It is suitable for the optimization of the CBM collection and distribution network in this block. It is also applied to optimize the pipe diameter and wall thickness of gas gathering pipe network, and achieves the purpose of saving the pipeline investment cost most.
