Method and device for detecting reversed-polarity seismic trace

The embodiment of the invention discloses a method and device for detecting areversed-polarity seismic trace. The method comprises the following steps: acquiring a signal value of each seismic trace at the same sampling point at the same moment in shot gather data; processing the signal values of the adjacent seismic traces to obtain energy change information between the adjacent seismic traces; and according to the energy change information between the adjacent seismic traces, determining polarity change information of the adjacent seismic traces in the shot gather data to obtain a reversed polarity seismic trace. 本申请实施例公开了一种反极性地震道的检测方法和装置。所述方法包括：获取炮集数据中同一时刻每个地震道在相同采样点的信号值；对相邻地震道的信号值进行处理，得到相邻地震道间的能量变化信息；根据相邻地震道间的能量变化信息，确定炮集数据中相邻地震道的极性变化信息，得到反极性地震道。
