Design of 3D GIS for coal-bed methane (CBM) gathering pipeline network in the Qinshui Basin

Coal-bed methane (CBM) gathering pipeline network is a complicated facility that involves large volumes of data and multiple disciplines. Considering the characteristics of the CBM gathering pipeline network such as large coverage, complicated landforms, multiple system elements and great difficulties in management, this paper presents a GIS database for CBM gathering network taking the Qinshui Basin as an example. This database combines 3D GIS technology and specific conditions of the gathering pipelines, with editing, query, analyzing, visualization and other functions. The 3D GIS and simulation software are combined to simulate and optimize the CBM gathering system. The research results can provide guidance for planning, design, operation, control, coordination and management of CBM gathering pipeline network.
