摘要
针对依-舒地堑地表条件和深层构造复杂、地震资料干扰波发育等特点,在精细处理方法和复杂构造精确成像技术上开展了研究工作,形成了以综合建模静校正、叠前去噪、精细速度分析、叠前时间偏移求取精确速度场、叠前深度偏移精确成像等为特色的地震处理技术,处理后成果剖面的波组特征、断裂及构造的成像精度都有一定程度的提高。
Based on the complicated structure of Yi- Shu data and well developed disturbing wave,the study was carried out on the fine data processing methods and complex constructs precise imaging technology. The seismic processing technology,characterized by comprehensive modeling static correction,stacking before noise edit,fine velocity analysis,prestack time migration for accurate velocity field,prestack depth migration accurate imaging,etc.,was formed,and has achieved some effect in raising wave group feature of the processed profile and the imaging accuracy of the fault and structure.
