三维地震勘探是目前国内外寻找石油、天然气、煤等资源的重要手段之一,然而提高分辨率是三维地震勘探中恒久不变的一个主题。本文就谈一下我在多年的一线工作中总结的提高分辨率的一些经验和方法。高分辨率地震勘探主要解决常规地震勘探在纵向和横向上难以分辨的地质问题(如小褶曲、小断层等),其任务是在野外采集有较高信噪比的宽频有效信号,为地震资料处理和解释提供基础资料。
Three-dimensional seismic exploration is one of the most important means to search for resources such as oil, natural gas and coal at home and abroad. However, improving the resolution is a constant theme in 3D seismic exploration. This article will talk about some of my experience and methods to improve the resolution summarized in many years of field work. High-resolution seismic exploration mainly solves the geological problems (such as small folds and small faults) of conventional seismic exploration that are difficult to distinguish vertically and horizontally. Its mission is to collect wide-band effective signals with high signal-to-noise ratio in the field, Processing and interpretation to provide basic information.
