Embodiment
[0034] In this embodiment, the coalbed methane in Baode District is mainly used as an example for illustration. It should be understood that the specific implementation may not be limited to the coalbed methane in Baode District.
[0035] figure 1 It is a flowchart of a volume fracturing treatment method for a coal seam provided by an embodiment of the present invention. The following will describe figure 1 The specific process shown is described in detail:
[0036] S1, acquiring geological feature information of the target area.
[0037] S2. Based on the geological feature information of the target area, a coal reservoir hydraulic fracturing fracture propagation model is established.
[0038] S3. Based on the coal reservoir hydraulic fracturing fracture propagation model, the interaction between hydraulic fractures and natural joints is simulated, and the simulation results are obtained.
[0039] S4. According to the simulation results, the factors affecting the interactio...
