Embodiment Construction
[0024] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.
[0025] Such as figure 1 as shown, figure 1 It is a flow chart of the method for improving the correlation quality of a vibroseis single shot by utilizing near-seismic source geophones to record according to the present invention.
[0026] In step 101, a geophone is embedded near the vibrator to record vibration signals. The method for recording the vibration signal of the ground surface requires a good coupling effect between the geophone and the ground surface, so as to record the vibration signal truly to the greatest extent. In one embodiment, a geophone is buried at a distance of 10 meters from the vibroseis. The geophone should be well coupled with the ground surface, and should be inserted tightly and buried firmly. figure 2 It is a sch...
