有关地震勘探资料分辨率问题的一些看法
|
摘要
油气藏的勘探、描述和管理,对高分辨率地震资料有着非常紧迫的需求。但资料处理中反褶积方法存在的实际的困难,以及对于资料"带限"问题理论上的困惑和资料解释长期形成的模式习惯的困扰,从资料采集—处理—解释各个环节,制约了高分辨率地震的实现。因此就需要解除理论上的困惑,排除习惯上的困扰,克服实际存在的困难,去努力适应石油工业对高分辨率地震勘探的需求。
Higher resolution seismic data are needed in today's reservoir identifications.But higher resolution of seismic data is at all time limited by practical trouble,theoretical puzzle and customary behavior.Residual wavelets have to be handed down after the deconvolution.The band-limited wavelet has become the deadline of to improve resolution.The conventional pattern of explanation turns into the golden rule.So we first have to free from the puzzle,then to shake off the custom,and to overcome the trouble on purpose of to improve resolution of seismic data.
