Abstract:Volcanic reservoirs in the Dixi area are quite rich in oil and gas resources.However they are characterized by complex near-surface structure,deep burying,complicated internal structures,and strong heterogeneity.Seismic imaging in the area faces serious problems such as static corrections,low-quality data,and difficult velocity analysis.In order to obtain exact volcanic reservoir imaging,we propose a new data processing strategy: solving serious statics problem with the dual-scale tomography inversion and the surface-consistent residual static corrections,obtaining high quality pre-stack data for seismic imaging with fine data preprocessing,gaining accurate velocity with well-controlled scanning velocity analysis.Finally,high-quality seismic imaging is achieved for volcanic re-servoir prediction
