摘要

采用提高信噪比目标处理,充分开发模拟地震老资料的潜力。该方法有三个特征:(1)具体情况具体分析,对低信噪比资料有针对性地反复精细处理;(2)解释性处理,地震处理贯穿地震解释全过程;(3)以工作站交互式处理为主要方式。新的处理剖面不仅提高了信噪比,而且提高了分辨率,可进行精细构造解释和层序地层解释。提高信噪比目标处理方法可在南方新区地震勘探部署中广泛使用,以减少投入,取得更好的勘探效果。
The analog seismic data with 6 and 12 folds have not satisfied yet to basin and trap evaluation in Shiwandashan Basin because of its low signal/noise ratio. It is necessary to develop the potential of the old available analog seimic data by a method of enhancing the ratio. The method has three characteristics: (1) precisely processing the data of low signal/noise ratio repeatedly; (2)interpretative processing, in which seismic processing accompanies the whole interpretation; (3)interactive processing with workstation. Its effect shows not only enhancing signal/noise ratio but also raising resolution on a processed seismic profile with a result of precise structural and seismic stratigraphic interpretation. Therefore, this method can be widely used in deployment of seismic prospecting in the unprospected areas of southern China and good exploration effects may be obtained with low cost.
