摘要
研究区数据是由 2个工区的三维地震数据拼接而成 ,不同工区的三维地震数据在频率、能量强弱和信噪比上都存在着差异 ,这给地震解释和地震反演带来了困难。而多工区三维地震数据连片处理结果往往使三维地震数据在频率、能量强弱方面失真 ,很难用于地震反演。因此 ,提出了基于小波变换的地震子波处理方法 ,马东唐南油田三维地震数据拼接的效果表明了该方法的有效性。
The data in our work area is composed of two 3-D seismic data sets. The two data sets are different in frequency, amplitude energy, and signal-to-noise ratio, which makes data interpretation and seismic inversion difficult to carry out. To concatenate the two data sets while overcome the above-mentioned problems, a method for wavelet processing is developed based on wavelet transform. The feasibility of the method is demonstrated by the application in Madong-Tangnan oilfield.
