Embodiment 1
[0073] Please refer to figure 1 , which is a seismic prediction method for shale reservoirs provided by the embodiment of the present invention, including the following steps S101-S106:
[0074] S101: Acquire seismic data in a target area, and preliminarily determine the spatial distribution range of shale reservoirs according to the seismic data; wherein the seismic data is seismic waves caused by artificial excitation of crustal vibration in the target area data. Among them, the spatial distribution range of shale reservoirs includes the horizontal development range and the vertical development depth horizon. In this step, the spatial distribution range can be understood as the range of preliminary prediction using seismic data.
[0075] It should be noted that the seismic data is obtained by seismic exploration. The principle is that the crustal vibration in the target area is caused by artificial excitation, and the seismic waves caused by the vibration are received by t...
