AI Technical Summary
In existing technologies, the quality control of the geometric arrangement of air gun seismic sources is easily affected by weak GPS signals or equipment failures, which can lead to interruptions in marine seismic acquisition operations and affect the acquisition progress and efficiency.
By analyzing the seismic wave waveforms received by each geophone in the air gun array, the first arrival time of the seismic waves is obtained, the actual travel time of the direct wave is calculated, a relational formula is established, the actual distance between the air gun and the geophone is calculated, and the characteristic values of the source geometry of the air gun array are monitored to achieve precise quality control.
It improves the accuracy of determining the geometry of the air gun array source, reduces the influence of external factors, ensures the construction efficiency of marine data collection operations, and reduces equipment maintenance costs.
