国内外中深层海洋地震勘探技术概述

Domestic and overseas technology of marine seismic survey in middle-deep water

传统的二维拖缆地震勘探针对一定的目地层深度进行作业,但对于深水区域和其他复杂区域,如坚硬的海底之下、盐下以及玄武岩下构造和碳酸盐岩储层等,会由于地震波无法触及部分地下目标而影响采集数据的真实性。文章详细介绍了国内外海洋中深层反射的采集技术,并对其进行了分析和总结,可对今后的中深层海洋地震勘探工作提供新的思路。

The traditional two-dimensional seismic exploration is suitable for certain depth targets. But in deep water areas and some complex regions such as the structure under hard sea bed, salt, basalt and carbonate reservoirs, the seismic wave can not reach part of the underground target, which will influent the data acquisition. This article introduces some seismic acquisition methods for middle-deep water at home and abroad in order to provide new insight for future survey of middle-deep marine seismic.
