本文主要是对叠前陆地数据线性处理进行总结和分类。根据产生地质模型的物理描述,指出它们有用的理由和容易出错的地方。由于处理中的限制较多,则其灵活性较小。灵活性越小也就意味着在存在随机噪声的情况下有更好的统计效果。所以,这里提出地表一致性的观点,并举例说明。有一种在地震上应用较少的测量方法,即与地表情况相关的地震道相位校正法,它使资料在每一深度点内都一致。估算和应用这些相位校正值叫“相位平衡”。其处理实例将在后面给出。本文是以欧洲勘探地球物理学家协会于1987年6月在南斯拉夫贝尔格莱德召开的第四十九届年会上发表的论文为基础,并参考布雷林克、戴维·哈其森于1984年在亚特兰大召开的勘探地球物理学家协会会议上发表论文的某些内容。
This paper mainly summarizes and classifies the pre-stack land-based data linearization. Based on the physical description that generated the geological model, points out the reasons for their usefulness and the error-prone areas. It is less flexible due to the more limited processing. The less flexible means that there is a better statistical effect in the presence of random noise. So, here’s the idea of surface consistency and an example. There is a less-used method of measuring earthquakes, that is, the seismic phase corre- lation method associated with the surface conditions that keeps the data consistent at each depth. Estimating and applying these phase corrections is called “phase balance.” An example of its processing will be given later. This article is based on papers published by the European Association of Exploration Geophysicists at the 49th Annual Conference held in Belgrade, Yugoslavia, in June 1987 and with reference to Brelekan, who in 1984 Some of the papers published at the Society of Exploration Geophysicists meeting in Atlanta.
