Seismic Exploration with Vibrator acquisition technique is the trend of land seismic exploration acquisition technique development at present, due to controllable
Focus compared with dynamite source there are frequency energy is controllable, safety and environmental protection, cost is low, construction efficiency is high etc. it is many a little, so more next
More pursued be subject to major petroleum geophysics oil company.Slip scan is in current Seismic Exploration with Vibrator acquisition technique
Important technology, due to shortening the firing time of adjacent two big gun, the sliding time of two big guns is less than the sweep length time, shortens
Construction time, improves construction efficiency, but the influence brought therewith is the harmonic wave interference noise of adjacent two big gun, this harmonic noise
Disturb larger, there is important influence to seismic data, reduce signal-to-noise ratio.The rule of slip scan harmonic wave interference is, next
The harmonic wave of big gun has the single-shot quality of a upper big gun large effect, and the harmonic wave of a upper big gun influences the single-shot quality of next big gun
It is smaller.
For the harmonic wave interference for how suppressing the adjacent big gun during slip scan, numerous scholars propose more side
Method, is had plenty of and harmonic wave is suppressed using force signal, has plenty of and harmonic wave is suppressed using the method for predicting harmonic wave.By
The above method, slip scan harmonic wave interference have certain suppression.
The content of the invention
The object of the present invention is to provide it is a kind of can be with the suppressing controllable seismic-source of suppressing controllable seismic-source slip scan harmonic wave interference
The method of slip scan harmonic wave interference.
The purpose of the present invention can be achieved by the following technical measures：
The method of the suppressing controllable seismic-source slip scan harmonic wave interference includes：Step 1, slip scan is carried out in controlled source
During work, the embedding detector near controlled source, records vibration signal；Step 2, the vibration signal of wave detector record is carried out
Processing, obtains preliminary wave；Step 3, preliminary wave and reference signal are subjected to convolution operation, ground vibration signal is calculated；With
And step 4, ground vibration signal and female record are subjected to related operation, obtain slip scan single shot record.
The purpose of the present invention can be also achieved by the following technical measures：

Close and calculate symbol.
The method of suppressing controllable seismic-source slip scan harmonic wave interference in the present invention, using apart from controlled source closer location
The ground surface vibration information that the wave detector at place recorded suppresses controlled source slip scan harmonic wave interference.Specific principle
It is：Using the wave detector tracer signal nearer apart from controlled source as coherent signal, each signal record is controllable every time
Real ground vibration signal when focus vibrates, which contains scanning fundamental signal and harmonic signal, because obtaining every time
This ground surface vibration signal obtained is not identical, especially harmonic wave interference, therefore this earth's surface obtained every time is shaken
The harmonic wave interference correlation in harmonic wave interference and scanning single-shot adjacent thereto in dynamic signal is poor, therefore is shaken using this earth's surface
Dynamic signal is related to mother's record progress, while corresponding single shot record is obtained, can effectively suppress other slip scan lists
Harmonic effects of the big gun to the single-shot.The present invention is exactly according to this principle, suppressing controllable seismic-source slip scan harmonic wave interference, effect
Preferably, the signal-to-noise ratio of slip scan seismic data can effectively be improved.
