长岭凹陷三维地震资料叠前连片处理方法

3-D Pre-stack Multitude Process in Changling Depression

长岭凹陷位于松辽盆地南部中央断陷带,对该区域7个区块的地震资料进行连片处理,有利于深化区域的地质认识,寻找更多的有利目标。提出了三维叠前连片处理流程,重点分析了连片处理中关键环节及其参数选择方法,该方法在应用中见到了明显的效果。

Changling depression lies on middle fault region of Songliao basin,and the seismic data of seven exploration areas is processed in multitude in order for deepening geologic understanding and finding more useful target.The paper presents the flow of 3 D Pre-stack multitude process,and emphasizes key points of multitude processes and method about selecting parameter.The method is effective in application.
