摘　　要：琼东南盆地发育大量垂向裂隙,垂向裂隙在油气运移成藏中起到了关键性的作用。但目前对于琼东南盆地垂向裂隙系统刻画方面的研究尚不深入。本文采用基于广义频谱分解的蚂蚁追踪裂隙识别方法对琼东南盆地垂向裂隙进行检测。实际应用表明该方法可以有效识别琼东南盆地垂向裂隙,有效降低了高频噪声对裂隙刻画的影响。因此,该方法适用于琼东南盆地垂向裂隙识别,为基底天然气垂向沟通提供了技术手段。A large number of vertical fractures are developed in Qiongdongnan Basin,which play a key role in hydrocarbon migration and accumulation.However,the research on the vertical fracture system characterization in Qiongdongnan Basin is still insufficient.In this paper,an ant tracking crack identification method based on generalized spectrum decomposition is used to detect vertical cracks in Qiongdongnan Basin.Practical application shows that this method can effectively identify vertical fractures in Qiongdongnan Basin,and effectively reduce the influence of high frequency noise on fracture characterization.Therefore,this method is suitable for vertical fracture identification in Qiongdongnan Basin and provides technical means for vertical communication of basement natural gas.
