摘要: 通过分析传统的二维地震资料处理不同基准面的静校正方法,指出这些方法在西部煤炭资源勘探中的局限性。在此基础上提出基于工区近地表基准面的静校正方法,把处理方法与解释紧密结合起来,通过实际应用,大大降低了传统二维地震交点闭合差的影响,提高了深度解释的可靠性。该方法适用于勘探范围广、工区地表起伏大的西部煤田勘察。

Abstract: The paper points out the limitations of traditional static correction methods in 2-D seismic data processing, provides a static correction method based on near survey surface which combines the processing method with interpretation.The method reduced the influence of difference in intersection greatly;the reliability of interpretation in depth is improved.It can be used in exploration of western coalfield with large range and wavy surface.
