Land Equipment for Broadband Seismic Data Acquisition and the Application

宽频带、宽方位、高密度地震数据采集是近年地震勘探的重要发展方向,随着现代电子设备的可靠性大幅度提高,使得"两宽一高"采集技术得以推广应用。本文重点介绍陆上地震采集可控震源设备(Nomad系列)和数字检波器(DSU1-508)针对采集需求所做的技术改进,如何在保证生产效率、降低采集成本的前提下,使高密度采集成为可能,并满足深层勘探和高精度勘探的需求。通过分析高密度采集数据的处理结果并与常规采集效果进行对比,结果表明新一代设备在拓宽频带,提高分辨率的同时,极大地改善了成像质量。

Broadband,wide azimuth and high density data acquisition are ever growing trend of seismic exploration in recent years.Conventional acquisition equipment and geometry scheme have been unable to meet the technical requirements for this development.With the reliability of modern electronic equipment greatly improved.On the premise of ensuring production efficiency and reducing acquisition cost,the updated seismic acquisition equipment makes high-density acquisition possible and meets the needs of deep exploration and high-precision exploration.This paper focuses on the technical improvement of land seismic acquisition of vibrator(Nomad series) and digital sensor(dsu1-508) and analyses the processing seismic results of high-density acquisition compared with that of conventional acquisition.The results showed that the new generation of equipment greatly improved the imaging quality while widening the frequency band and improving the resolution.
