| 摘 要： | 实际地下介质广泛存在各向异性,采用各向同性叠前深度偏移方法成像精度较低。在理论分析的基础上,给出了一套VTI各向异性叠前深度偏移处理流程,即在各向同性叠前深度偏移的基础上,求取VTI各向异性参数,进行VTI各向异性叠前深度偏移。将该流程应用于JZ工区实际资料处理中,并与各向同性叠前深度偏移成像效果进行了对比,结果表明,VTI各向异性叠前深度偏移技术是提高复杂构造的成像精度、改善成像效果的有效方法。

| Abstract: | Actual subsurface media is characterized by extensive anisotropy, which leads to relatively low imaging accuracy by using isotropic pre-stack depth migration method.Therefore.a workflow of VTI anisotropic pre-stack depth migration was proposed.On the basis of isotropic pre-stack depth,VTI anisotropic parameters are obtained and VTI anisotropic pre-stack depth migration is carried out.The workflow was applied to the data processing in JZ block.The comparison between VTI anisotropic and isotropic pre-stack mi... |
