本文叙述了地震波振幅异常的提取及平面显示方法。方法要点有三:其一,对地震记录进行精细、保真处理,尽最大可能消除非地质因素的影响;其二,采用振幅扫描方法,并解释目的层位,拾取其振幅信息;其三,用加权最小二乘法对数据进行网格化处理并做激光彩色显示。这就为综合分析油气田提供了一种重要参考图件。 This paper describes the extraction of seismic amplitude anomalies and planar display method. There are three main points of the method: first, to finely and fidelity the seismic records and to eliminate the influence of non-geological factors to the greatest extent possible; secondly, using the amplitude scanning method to interpret the target horizon and pick up the amplitude information; thirdly, Weighted Least Squares Data is gridded and laser colorized. This provides an important reference picture for a comprehensive analysis of oil and gas fields.
