Abstract

Vibrosismik, sismik aramaların önemli bir yöntemi olup, uygulanan sweep sinyalinin parametreleri yerin derinliklerindeki kaya katmanları ile değişir. Vibrosismik’te sismik verinin
frekans aralığının kontrol edilebilmesi son derece faydalıdır. Vibratör, sismik yöntemlerde kullanılan kontrollü bir enerji kaynağıdır. Günümüzde vibrosismik karada yapılan sismik arama çalışmalarında en çok kullanılan ve tercih edilen sismik enerji kaynağıdır. Uygun giriş sinyali, frekansı bir frekans band genişliği içinde değişen sinüzoidal dalga formundadır. Yüksek ayrımlılık ile yeraltı görüntüleri elde etmek için, sweep sinyalinin genliği ve Klauder dalgacığının genliği vibrosismiğin önemli parametreleridir.
Bu çalışmada, farklı sweep parametrelerine göre Klauder dalgacık genliğinin değişimleri araştırılmıştır. Testlerde çeşitli sweep sayıları, sweep uzunluğu, pik kuvveti oranı ve sweep band genişliği temel alınarak yapılmıştır. Sonuçlar teorik değerlerle karşılaştırılmış olup, test edilen parametreler atış ve veri işlem aşamalarında değerlendirilmiştir.

The effect of sweep signal parameters on correlation wavelet

Year 2021, Volume: 42 Issue: 2, 199 - 231, 20.08.2021

Abstract

Vibroseis is an important seismic exploration method whose sweep signal parameters vary with rock layers deep in the earth. Controlling of sweep signal frequency band is extremely useful method in vibroseis data acquisition. The vibrator is a controlled energy source employed in seismic methods. Nowadays it is widely used and preferable seismic source for land seismic exploration. Suitable input signal is typically a sinusoid that changes frequency within a bandwidth. To obtain high-quality subsurface images, amplitude of the sweep signal and Klauder wavelet is important parameter of vibroseis.
In this study, amplitude of Klauder wavelet variations with respect to different sweep parameters are investigated; tests have been made based on a variety of sweep numbers, sweep length, peak force ratio and sweep bandwidth. The results have been compared with theoretical values and the tested parameters are evaluated in the shot and processing domain.
