【摘要】 通过对泌阳凹陷地震地质条件和原始地震资料情况的介绍,指出了本工区以往处理的成果剖面在实际应用中存在的问题:不同区块的频率、相位不一致问题;区块之间的闭合差问题;各区块拼接处的边界效应问题。针对存在的问题,提出了相应的解决办法,同时讨论了在连片处理过程中应当关注的几项技术及应用注意事项,包括面元定义的方法、静校正方法的应用、叠前去噪方法的分析、反褶积方法的选取、子波整形等方面,并对每项技术的应用方法、实施过程中应当遵从的原则提出了自己的看法。最后,对连片处理的效果进行了对比分析:经过连片处理的剖面消除了原处理剖面存在的不足,整体形态合理,断层、断面清晰可靠,局部构造清楚,剖面的可解释性强。更多还原

【Abstract】 This paper introduces the seismic geology and original seismic data of Miyang Sag,and points out the problems in actual application of previously processed profiles of this study area: different frequency and phase in different blocks;different discrepancies in closing;and boundary effect between blocks.Corresponding solutions are proposed,and the technologies for continuous coverage processing and the points for attention are discussed,including bin definition method,static correction method,analysis of prestack noise removal,selection of deconvolution method,and wavelet shaping.At last,the processing effects are correlated.Continuous coverage processing profile eliminates the shortcomings of original profile.Its overall shape is more reasonable,faults and cross-sections are clear,local structures are vivid,and the profile is more interpretable.更多还原
