摘    要:随着地震勘探目标的越来越复杂化,地震勘探已经从经验化、定性化的过程,发展到准确化、定量化。计算机及其相关技术的发展进一步为地震勘探的现代化提供了保证。这里就地震数据采集方面的科学化分析提出了系统的解决思路,即由采集参数系统分析可获得最佳的地震观测参数;地质模型分析可帮助用户在复杂地质结构下设计曩有利的接收排列;地震资料品质分析可定量地评价地震采集到的单炮资料的品质。它既可以用于采集参数试验过程中参数的优先,也可以用于施工过程中资料的质量监控。

关 键 词:地震数据采集  模型分析  地震资料品质  质量监控  地震勘探  单炮资料

NEW CONCEPT FOR SEISMIC DATA ACQUISITION
Abstract:As the target structure complexity of seismic exploration is, for recent decades, increasing, the seismic acquisition technique has to improve quickly. Based on the computers and their related techniques, it has, in fact, developed from the early experiential and qualitative to nowadays accurate and quantitative process. This paper propose a systemic solution scientifically to analyze seismic acquisition process as the following: First, The optimal parameters of acquisition geometry are determined by the system analysis of seismic acquisition. Then with geological model's help, the reasonable receiving spreads for complicated geological conditions are designed. Quantitative data analysis is used to evaluate the quality of single shot record, which is not only suitable for to optimize the testing parameters, but also for QC during seismic record.
Keywords:seismic acquisition parameters  model analysis  quantitative data analysis  QC
