利用高清蚂蚁体精细解释复杂断裂带
|
摘要
在渤海海域中浅层断裂系统较为复杂的地区,常规地震解释方法效率较低,断层组合不精细。随着深度增加,常用于辅助断层解释及组合的方差或相干属性清晰度明显降低,已不满足断层组合的需要。为此,针对研究区的地质特点,结合现有资料条件,提出一套高清蚂蚁体生成技术。该技术不同于以往对蚂蚁追踪参数进行简单优选和对比的技术,而是以增强断层连续性和降噪为目的,通过优选两类参数组合,对数据体进行多重蚂蚁追踪计算,并穿插多步噪声削减,最终得到与研究区断裂高度匹配的高清蚂蚁数据体。使用该数据在短期内快速完成浅层470条断层组合,有效提高了断裂解释精度,为圈闭搜索及落实奠定了坚实基础。
In middle-shallow layers of Bohai Sea area,most of fault systems are extremely complicated.Conventional seismic interpretation methods are not efficient,fault combinations cannot be well depicted.The variance or coherent attributes often used in fault interpretation,they do not work when faults are in deeper strata.These attributes are no longer satisfied with fault combination in that depth.According to geological characteristics of the study area,this paper proposes a set of highdefinition(HD)ant-tracking volume generation techniques.Conventional ant-tracking focuses on only one-parameter optimization.Our new approach is different,it emphasize the improvement of fault continuity and noise removal.According to two kinds of parameter combinations optimized,multiple ant-tracking attributes are extracted from the data volume,accompanied by several steps of de-noising methods.Finally,the HD ant-tracking volumes are obtained,which match very well with faults in study area.With the proposed approach,470 fault combinations are confirmed in a short time and the fault interpretation is improved,which lays a solid foundation for trap searching.
