| 摘 要： | 洋心次凹是苏北盆地白驹凹陷内一个小型次级箕状凹陷,具有断裂系统复杂、断层密度高、圈闭面积小等特征。前期勘探成果表明洋心次凹具有良好的油气勘探前景,但其构造落实程度较低。为此本文从该区断裂系统入手,利用多种属性提取、多种剖面显示、多个方向剖面解释和加大剖面解释密度的"三多一密"解释方法进行小断层的识别与描述,提高了构造落实精度,取得了较好的应用效果。

| Abstract: | Yangxin Sub-sag is located in Baiju depression of Subei Basin with complex fracture systems,dense faults and small traps.Early explorations showed that Yangxin Sub-sag seemed to be good prospects for oil and gas exploration,but the structure delineation was not confirmed.Starting from studying fracture system,we identify and describe minor faults by multi-attribute extraction from multiple sections,multi-direction profiles.Using this seismic subtle interpretation method,the structure delineation has been im... |
