摘要
随着岩性和精细地震勘探进一步的拓展,近地表结构的综合分析显得尤为重要。近几年静校正技术增加了许多新的内容,但这些方法相对比较独立,自成体系。静校正是一套复杂的系统工程,涉及的因素很多,特别是连片处理或考虑以往的静校正相关参数时,就必须综合分析来自不同时期、不同信息的表层资料,建立近地表模型,拥有相应的计算方法和技术平台。近地表结构解释系统是一套专用于表层结构综合分析研究及静校正建模计算为一体的专业化应用系统,为分析表层调查点速度、厚度分布规律,及表层结构特点和静校正方法研究提供了技术平台,促进了油田地震辅助信息管理的进步和静校正技术的提高。
With the progress of lithology and accurate seismic exploration, the analysis of near surface structure becomes more important. The static correction technology has kept on progressing with more and more new methods in recent years, but they are relatively isolated. Because it is a complicated project involving many factors, especially considering multi-survey processing or previous static correction parameters, the corresponding computation and technology platform are needed to analyze many types of near surface information of different stages and build near surface structural model. The near surface structure interpretation system is a professional platform integrated with near surface structure analysis and static correction modeling Thi~ system provides a technological platform for the analysis of velocity and thickness distribution of near surface research points and the study of static correction methods, and improves the management of seismic assistant information of oil field and the static correction technology.
