摘　　要：以GIS的栅格数据结构为基础 ,按照油气运移的机理 ,借鉴地表水流向分析的GIS建模方法 ,构建了在GIS支持下开展油气运移路径模拟的详细算法 ,提出了基于DEM的油气运移路径模拟的基本流程。以我国北方某盆地为例 ,成功地模拟了该盆地深层天然气的运移路径。On the basis of raster data structure of GIS, directed by oil and gas reservoir formation theory, and using the GIS modeling method of surface water flow direction analysis for reference, this paper designs a special GIS-based algorithm to simulate oil and gas migration pathways, and proposes a GIS-based oil and gas migration pathway modeling flow. As a case of application, the deep-buried oil and gas migration pathways has been simulated successfully in some basin of northern China.
