摘　　要：判识深盆气圈闭一般有 3种方法 :地质条件叠合法 ,理论模拟计算法 ,探测结果推定法。在深盆气勘探开发的不同阶段 ,由于研究的内容不同 ,对深盆气圈闭的判识采用的方法也不同。利用这 3种方法识别深盆气圈闭 ,可以确定圈闭的分布和发育范围 ,同时认为 ,深盆气圈闭的形成存在一个地质门限 ,进入这一门限 ,深盆气才可在圈闭内聚集成藏。将实际资料分析与理论计算相结合 ,预测了鄂尔多斯深盆气圈闭的发育范围 。There are three methods for identifying deep basin gas trap including superimposition method with geological conditions, simulating numeration in theory and presuming method using detection results. These methods can be used in the different stages and conditions of exploration and exploitation. By identifying the deep basin gas trap, the distribution and developing range of deep basin gas trap can be confirmed, which has important instructional significance for finding deep basin gas reservoir. The combination method of practical data analysis and theoretical numeration has been used to predict the developing range of deep basin gas trap in Ordos Basin, which can provide the basis for exploration and development of deep basin gas in this area.
