摘　　要：以延吉盆地为例,利用地理信息系统技术对盆地油气勘探目标进行优选。采用图层叠加法、神经网络法和模糊聚类对盆地的静态地质要素进行评价,对于油气动态地质作用主要考虑在地理信息系统功能下实现油气运移路径模拟,从静态和动态两个方面对延吉盆地的油气资源进行评价,并对各个要素的评价方法和流程进行详细的分析,在延吉盆地中优选出7个有利区带,为勘探规划提供重要的决策依据,并证实该评价方法对油气资源评价的可行性和有效性。Taken Yanji Basin as an example, geographic information system is used to select the oil and gas exploration optimal target in the basin. Lay superposition, neural network and fuzzy clustering methods were adopted to evaluate the basin＇s static geological elements. For the dynamic oil and gas geological process, the main consideration was imitating the oil and gas migration pathways under geographic information system. The authors evalu- ated the oil and gas resources of Yanji Basin from both static and dynamic aspects and analyzed the evaluation methods and procedures for all the elements in detail. By using this method, seven advantage areas were selected in the basin to provide important decision basis for exploration plan, which confirmed the feasibility and efficiency of this method in oil and gas resources evaluation.
