[0053] It should be noted that the embodiment of the present invention provides a focal mechanism inversion method for ground microseismic monitoring data of hydraulic fracturing, and establishes a set of reliable, practical and efficient microseismic focal mechanism inversion process. The so-called "focal mechanism" is a concept introduced from the field of natural earthquakes, which refers to the mechanical process in the source area when an earthquake occurs.
[0054] The method of this embodiment mainly utilizes the information of the initial motion of the P wave to perform the inversion of the source mechanism of the hydraulic fracturing fracture. The theoretical basis is: when the pure shear dislocation of the fault occurs underground, the P wave seismic phase received on the ground has the characteristic that its initial motion polarity is distributed in four quadrants. figure 1 A schematic diagram of the shear dislocation fault model and its ground polarity distributio...

[0084] Figure 11 is a structural schematic diagram of an inversion system for a hydraulic fracture source mechanism according to another embodiment of the present invention. Refer below Figure 11 To describe the structure and function of the system in detail.
[0085] Such as Figure 11 As shown, the system includes an azimuth calculation module 111 , a model building module 112 , a departure angle calculation module 113 , a P wave initial motion polarity determination module 114 and a nodal plane solution calculation module 115 . The above five modules execute step S110 , step S120 , step S130 , step S140 and step S150 in the first embodiment respectively, which will not be repeated here.
