摘要

目前我国深海地震勘探主要使用气枪震源激发和单道地震拖缆接收,浅部地层分辨率较低,且无法进行速度分析、覆盖叠加等精细处理。为了解决此问题,提出了深水浅地层高分辨率多道地震探测技术,研究适用于深水的大能量等离子体震源和96道光纤水听器地震拖缆等设备。系统部分联调和测试表明,该技术所研发系统设备地层分辨率可达1.2 m,且具有应用水深范围广、使用方便等特点,可以满足大洋矿产资源调查、远海海洋环境调查的需求。
In the present deep-sea seismic exploration of China air-gun is used as the seismic source for emitting and a streamer of single-channel seismic system is applied for signal receiving,so that the resolution of shallow strata is low and some refined processings such as velocity analysis and coverage overlaying are difficult.To solve this problem,a deep-sea high-resolution multi-channel seismic exploring system is developed for shallow strata,which uses a high-energy plasma seismic source and a multi-channel streamer composed of 96 fiber-optic hydrophones.It has been shown from the tests of the system that by using this system the resolution of the strata can reach to 1.2 m.In addition,the system can be conveniently applied in a large water extent and can meet the requirements of ocean mineral resource investigations and deep-sea environmental surveys.
