Embodiment Construction
[0050] In order to make the above and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments are listed below and shown in the accompanying drawings in detail as follows.
[0051] Such as figure 1 as shown, figure 1 It is a flow chart of the real-time monitoring method for the dynamic distribution of ground microseismic fracturing fractures of the present invention.
[0052] In step 101, deploy natural seismic station instruments or broadband geophones in a uniform, symmetrical, sufficient, and continuous manner on the surface or in shallow wells above the hydraulic fracturing area of the reservoir to obtain hydraulic fracturing reconstruction data of tight reservoirs x, y, z three-component microseismic broadband data; use high-resolution, broadband three-component natural seismic station instruments or broadband geophones, and optimize the ground microseismic observation system on the surface or in shallow wells abov...
