Refer to shown in Fig. 1, the method utilizing first break time to detect shot gather data fast of the embodiment of the present invention comprises the following steps:
A, in advance a selection single big gun from several tentative single big guns, make all seismic traces clear based on the primary wave waveform of this single big gun and relation between its first break time, geophone offset and first arrival velocity of wave is correct, then using seismic trace each in all seismic traces based on the first break time of this single big gun as the standard first break time of this seismic trace.
The velocity of wave change caused according to pickup precision and the change in location of each seismic trace in advance sets the first break time range of tolerable variance of this seismic trace, by the error of each seismic trace because of its pickup precision generation, and the velocity of wave variation error to cause because of change in location superposes, and using the first break time range of tolerable variance of the total error after superposition as this seismic trace.In the present embodiment, first break time range of tolerable variance is 30 milliseconds is better.
The mistake road environmentally disturbing (such as mechanical wave etc.) to cause in advance accounts for the ratio setting tolerance number of channels of total seismic trace, and in the present embodiment, tolerance number of channels is 30% of total earthquake number of channels is better.
The data of b, each seismic trace Real-time Collection single big gun.
C, each seismic trace obtain respective first break time from the data collected separately.
D, calculate the error of the first break time of each seismic trace and its standard first break time preset separately.
E, judge whether the first break time error of each seismic trace exceeds the first break time range of tolerable variance preset separately; If exceeded, perform step f; If do not exceeded, then perform step g.
If f exceeds, then judge the first break time mistake of this seismic trace, then perform step h.
If g does not exceed, then judge that the first break time of this seismic trace is correct, then perform step h.
H, judge whether the quantity of the seismic trace of first break time mistake exceeds tolerance number of channels; If exceeded, perform step I; If do not exceeded, then perform step j.
If i exceeds, then judge the shot gather data mistake of this single big gun, namely this single big gun is blown-out shot or inclined big gun, after this by the red histogram output display of the attributed graph of single big gun of its shot gather data mistake, then performs step k.
If j does not exceed, then judge that the shot gather data of this single big gun is correct, namely this single big gun is normal big gun, after this by the green histogram output display of the attributed graph of single big gun correct for its shot gather data, and synchronously carries out audible alarm to point out mistake, then performs step k.
K, repeat step b ~ i, until the shot gather data completing all single big guns detects.
Because the embodiment of the present invention has preset tolerance number of channels, and the standard first break time of each seismic trace and first break time range of tolerable variance, like this, when each seismic trace Real-time Collection single big gun data and after obtaining its respective first break time, as long as by with standard first break time, the comparison of first break time range of tolerable variance and tolerance number of channels, just can judge that whether the shot gather data of this single big gun is correct fast, thus the requirement of process in real time, and the embodiment of the present invention all carries out detecting thus achieving complete detection for each single big gun, in addition, the embodiment of the present invention is obviously a kind of detection means automatically, thus can be in real time on-the-spot, comprehensively, automatic realization carries out quality testing to geological data.
