摘要
针对鄂尔多斯盆地GFZ地区宽方位三维可控震源资料的特点,利用GeoEast处理系统中层析静校正、叠前保真噪声压制、高分辨率处理、OVT域处理、叠前时间偏移及方位各向异性校正等处理技术,得到了高品质的叠加、偏移及分方位角成果资料。实际应用效果表明,应用GeoEast处理系统取得了较好的处理效果,为地震解释开展叠前反演、构造解释及裂缝预测等提供了资料保证。该套GeoEast处理系统三维处理流程可在长庆探区推广应用。
A wide-azimuth 3D vibroseis survey was carried out recently in the GFZ area,Ordos Basin.We have processed this wide-azimuth 3 Ddataset with different tools provided by GeoEast.The key processing techniques include:tomo-static corrections,prestack noise suppression,high resolution processing,offset vector tile(OVT)processing,prestack time migration,and azimuthal anisotropy corrections.High-quality stacks,migrations,and different azimuth stacks data are obtained.Our application results show that GeoEast processing system achieves good success,which provides an excellent dataset for prestack inversion,structural interpretation and fracture prediction.
