GEOPHYSICS, published by the Society of Exploration Geophysicists since 1936, is an archival journal encompassing all aspects of research, exploration, and education in applied.
International Union of Geodesy and Geophysics (IUGG) is a non-governmental, scientific organization, established in 1919.IUGG is one of the 40 scientific Unions and Associations presently grouped with...
地震断层检测是建立地球储层模型的关键任务,而高精度、高效率、高分辨率的检测结果是精确地质构造解释的重要保障。随着人工智能算法在目标检测领域的发展,利用深度卷积神经网络预测地震数据中的断层位置成为了研究热点。神经网络通过从地震反射信息中提取断层的潜在特征,并抑制背景噪声的干扰,建立了一种从地震数据到目标断层的非线性映射关系,从而实现端到端的快速预测。目前主流的断层智能检测方法是使用大规模合成数据训练...
多尺度地震波数值模拟可以同时兼顾大尺度宏观效应和小尺度精细结构,从而有效地节省计算量,在实现过程通常需要对局部模型进行细化。基于有限元方法的域缩减法,可以灵活处理局部复杂结构和起伏地表的跨尺度问题,是实现多尺度模拟的常用手段之一。在处理过程中,过渡区域需要对外域(粗网格)波场进行插值,实现上采样,以适应内域(细网格)的波场(图1)。然而,常用的波场插值方法精度较低,通常只能实现较小的上采样倍率(M...
波场分离方法可以剔除地震数据中的干扰信号,保留有效信号,在数据处理领域具有重要地位。传统滤波方法需要在变换域设置衰减带,然而,衰减带过宽将导致信号和噪音无法有效分离,过窄则会引入数值假象。
地震波正演模拟是逆时偏移(Inverse time migration,RTM)和全波形反演(Full-waveform inversion, FWI)的基础,在地震数据处理过程中起着关键作用。与传统的时间域方法相比,频率域方法具有适合多炮计算、便于模拟粘滞效应、易于并行运算等优点。频率域弹性波正演模拟中的传统9点方法(图1a)适用于任意不等的空间采样间隔,具有很强的灵活性,但需要很细的网格划分才...
The research carried out at the Istituto Nazionale di Ricerca Metrologica (formerly Istituto di Metrologia «G. Colonnetti») aiming to develop a transportable ballistic absolute gravimeter e...
The Vulci archeological site was object of interest by the Soprintendenza ai beni culturali dell’Etruria meridionale (Italian government department responsible for southern Etruria’s cultural heritage...
Annals of Geophysics is a bimonthly international journal, which publishes scientific papers in the field of geophysics sensu lato. It derives from Annali di Geofisica, which commenced publication in ...
