三维地震目标处理在天然气勘探中的应用

3-D Seismic Target Processed Information Application in Gas Exploration in Liuzhuang Area

目的：在刘庄地区寻找有利的天然气勘探目标，开展三维地震资料目标处理。方法：运用道编辑、宽带滤波、多次叠加、叠后反褶积等多种新技术、新方法提高资料品质。结果：基本解决了地层对比、小断层识别、断层组合及油气分布等诸多难题。结论：三维地震目标处理能有效地改善新老油气田地震资料的品质，可以为地质研究人员提供更多有效的地质信息，为寻找有利圈闭提供资料保证。

Long term exploration veri fices that there is a advantageous oil & gas explorational prospect in Liuzhuang Area. But old 3-D information haven' t evaluated it because the target is very deep, structure is frag-ment, oil & gas distribution is very complicated. Then we proposed 3-D seismic information target processed with track edition, broadband filter, multiple stack, deconvolution after stack. The information quality is more im-provement than before. It basically has soluted stratum comparation, little fault identification, fault combination and oil & gas distribution many problems in application. Old and new oil & gas fields seismic information quality is improved effectively may provide us more effective geological research information to find out prospective traps.
