Abstract: A new approach of the geometrical layout of oil and gas gathering pipelines is presented.First,the shortest geometrical layout of gas-gathering pipelines can be determined by adding Steiner poirits beyond the wells and stations with SI algorithm without considering the topo-graphical constraints. Then the layout can be changed to satisfy topographical constraints,oron the basis of the results some options can be set up and the final layout determined by using the critical path method.

摘要： 油气集输管网几何布局方法是在不考虑地形因素时,用SI算法确定了在井站以外引入Steiner点时集输管网的最短几何布局。工程技术人员根据地形因素对其结果进行局部调整或提出若干可行几何布局方案,用关键路线法确定出最终几何布局。
