【摘要】 地震资料连片处理的目的是尽可能地克服不同年度、不同仪器、不同施工参数等造成的影响,同时消除不同的处理参数及处理流程所导致的差异。连片地震资料可以用于整体区域地震解释和地质认识。根据新老资料采集参数的特点,在静校正、叠前去噪、振幅补偿、叠前叠后提高分辨率等方面进行攻关,系统地解决了新老资料连片处理中的关键问题。通过处理资料的分析认为连片资料比较适合构造解释,而属性研究必须根据具体情况,一般是面元均化的网格与单块网格相比,网格差别大的,最好使用单块处理的资料,差别小的或者网格没有差别的,采用连片处理的资料进行研究。更多还原

【Abstract】 Seismic data joining processing is to overcome the impacts caused by variation of years,instruments as well as operation parameters,and to eliminate differences resulting from various processing parameters and treatment scheme.Joining seismic data may be used for overall regional seismic interpretation and geology understanding.On the basis of the features of the old and new data recording parameters,this paper has systematically solved key issues in old/new data joining processing through tackling the key problems such as statics correction,noise removal before stacking,amplitude compensation as well as resolution improvement before or after stacking.Through the analysis of processed data,the author thinks that joining data is better suitable to structural interpretation,while the study of attributes must depend on specific circumstance.In general,the grid of bin equalization is compared with the monoblock grid.If there is a large grid difference,it is better to adopt the monoblock processed data,or to adopt the joining processed data.更多还原
