摘    要:逆时偏移(RTM)成像波场逆推具有计算量大和运算速度慢的问题。为此,根据叠前深度RTM算法的特点,运用稳定条件、边界条件、成像条件3个要件并基于消息传递接口,提出全波波动方程叠前深度RTM成像并行算法。与传统柯西霍夫叠前深度偏移算法进行对比的结果表明,该算法能够较好地对地震数据进行偏移成像,成像效果优于传统算法并且并行速度较快。

关 键 词:逆时偏移  稳定条件  边界条件  成像条件  消息传递接口

Abstract:The large calculation capacity and slow running speed restrict the development and application of Reverse Time Migration(RTM).The paper proposes a full wave equation pre-stack depth RTM parallel imaging method based on the characteristics of Message Passing Interface(MPI) and RTM which applies the three conditions,and compared with the Kirchhoff pre-stack depth method,results show that the efficiency of MPI parallel method is good,it can process the seismic data migration imaging well and the parallel speed is fast.
Keywords:Reverse Time Migration(RTM)  stability condition  boundary condition  imaging condition  Message Passing Interface(MPI)
