摘　　要：萨北北二西井网密集,多年来没能利用大量井资料合理组合断层,特别是区块中央部位断裂复杂,对注采关系影响很大。采集三维地震后,把地震资料和井资料充分结合来研究断层。以地震解释的断层为基础,在三维空间利用相干体分析技术、正交切线法检查技术进行断点的空间归位、断层的空间组合,同时结合未组合断点寻找地震未解释的小断距断层,最后建立精准断层模型。结果表明该方法提高了断点组合率,对断层的认识更加清楚可信。The north Ⅱ west tract of saertu north area is a dense well pattern region,but these well information can not be used in rational fault combination,especially in the middle of research block where faults are well developed.It has a great impact on injection-production relationship.After 3D seismic acquisition,the author combined seismic and well data fully to research the faults,based on the faults explained by seismic,then used seismic coherence analysis technology and orthogonal tangent check technology in 3D space to combine breakpoints and faults,then according those unassembled breakpoints to look for some small faults that can not be explained by seismic,lastly established accurate fault model.The research shows that this method improves the efficiency of breakpoint combination and the recognition of the faults are more clear and credible.
