The shale gas currently being explored and developed in China's basins, basin margins, and hilly and mountainous areas belongs to "mountain-type" shale gas.

[0053] S1. Collect exploration data and seismic data of the target area, and perform geological micro-structural analysis on the target area based on the exploration data and seismic data to obtain regional micro-structural characteristics of the target area.

[0054] In the embodiment of the present invention, the exploration data refers to relevant information obtained by the research team through exploration in the target area.

[0067] In the embodiment of the present invention, the ant tracking algorithm is a technology used for seismic data processing, which identifies underground cracks and faults by simulating the behavior of ants looking for food. The core idea of ​​the ant tracking algorithm is to use the pheromones left by ants when looking for food to track cracks. These pheromones can be used by other ants to find the shortest path.
