Abstract：In order to improve the bedrock imaging quality and the fracture prediction accuracy in buried hills,a 3D wide-azimuth seismic survey in Moliqing Depression,Yitong Basin was conducted.This dataset is processed with distinctive processing tools provided by GeoEast System,such as static corrections,denoising,amplitude compensation,deconvolution,and residual static corrections.Then we use the offset vector tile (OVT) domain processing techniques,and obtain the prestack time migration imaging with azimuth information.These OVT processing results have much more azimuth anisotropy information,which provides a solid foundation for the subsequent fracture prediction and reservoir inversion.
