摘要
海洋浅地层剖面技术是目前最主要的海洋高分辨率浅地层结构地球物理调查方法,广泛应用于天然气水合物调查、海洋井位调查和海洋工程调查等项目中。目前,最常用的两种浅地层剖面技术是Chirp技术和参量阵技术。本文从勘探分辨率及穿透能力的基本原理出发,分别介绍了两类浅地层剖面仪的工作原理,并通过典型设备的技术参数及剖面的对比分析它们各自的技术特点。
Marine sub-bottom profile technology which is currently the most important high resolution marine geophysical survey method in shallow stratum structure, is widely used in marine hydrate investiga- tion, marine wells investigation and marine engineering survey project. At present, two kinds of shallow profile technology are the most commonly used Chirp technology and parametric array technology. This paper firstly introduces the basic principle of resolution and penetration of the sub-bottom profile, then the working principle of two kinds of subbottom profiler, finally analysis of their technical characteristics by comparing the technical parameters and the profile of the typical equipment.
