Abstract

Seismic processing on cross-spread gathers is a valuable but underexploited strategy. To do it properly, sources from a single source line and receivers from a single receiver line must be ordered in a physically sensible way, so that adjacent sources or receivers on a surface diagram are physically near each other. But determining such an ordering is a challenge on irregularly acquired land data. I propose novel automatic ordering algorithms using tools from graph theory that minimize large gaps and preserve the sequential patterns found even in highly irregular acquisition. Java source code is available.

交叉展布采集的地震处理是一种有价值但未得到充分利用的策略。要正确地进行处理,来自单个源线的源和来自单个接收线的接收器必须以物理上合理的方式排序,以便地表图上相邻的源或接收器在物理上彼此靠近。但是,对于不规则采集的陆地数据来说,确定这样的排序是一项挑战。我提出了新颖的自动排序算法,利用图论工具,最大限度地减少大的间隙,并保留即使在高度不规则采集中也能发现的顺序模式。提供 Java 源代码。

期刊介绍: Geophysics, published by the Society of Exploration Geophysicists since 1936, is an archival journal encompassing all aspects of research, exploration, and education in applied geophysics. Geophysics articles, generally more than 275 per year in six issues, cover the entire spectrum of geophysical methods, including seismology, potential fields, electromagnetics, and borehole measurements. Geophysics, a bimonthly, provides theoretical and mathematical tools needed to reproduce depicted work, encouraging further development and research. Geophysics papers, drawn from industry and academia, undergo a rigorous peer-review process to validate the described methods and conclusions and ensure the highest editorial and production quality. Geophysics editors strongly encourage the use of real data, including actual case histories, to highlight current technology and tutorials to stimulate ideas. Some issues feature a section of solicited papers on a particular subject of current interest. Recent special sections focused on seismic anisotropy, subsalt exploration and development, and microseismic monitoring. The PDF format of each Geophysics paper is the official version of record.
