摘　　要：油气运移路径模拟是油气运聚史模拟中难度最大、最复杂的内容之一。油气运移的路径模拟不仅要体现油气运移的动力,还要体现其运移的通道因素。以地理信息系统(GIS)的网格数据结构为基础,按照油气运移的机理,构建了基于GIS的油气运移路径模拟流程和算法,并成功地应用于延吉盆地,有效揭示了该盆地大砬子组时期油气的运聚规律,为该盆地下一步勘探方向提供了有利的参考依据。Imitation of oil-gas migration path is one of the most complicated and most difficult jobs in the history of oil-gas migration and accumulation. It does not take the migration path into consideration,but also the pathway. Based on the grid data structure of GIS and the mechanism of oil-gas migration,a stimulated process was put formard for oil-gas migration and algorithms. Using the process and algorithms to analyze Yanji Basin,the oil-gas migration and accumulation regularity of Yanji Basin were revealed during the Dalizi period,for the basin step exploration direction provides favorable reference.
