Isochronous seismic slice acquisition method, reservoir prediction method and device

The invention discloses an isochronous seismic slice acquisition method and a reservoir prediction method and device, and the method comprises the steps: obtaining the position information and drift distance of a reference point and a reference point in a target layer slice of a seismic data body; for any point except the datum point and the reference point in the target layer slice of the seismic data volume, determining the drift distance of the point according to the position information of the point and the position information and the drift distance of the datum point and the reference point; and drifting each point in the target layer slice along the depth direction in the seismic data volume according to the drifting distance of the point to obtain an isochronous seismic slice. The isochronous seismic slices can be reasonably cut from the seismic data volume, and a data basis is provided for realizing reasonable prediction of a reservoir. 本发明公开了一种等时地震切片获取方法、储层预测方法和装置，所述等时地震切片获取方法，包括，获取地震数据体目的层切片中基准点和参考
