电磁振动技术应用于地震勘探激发源的认识
|
摘要
当前,随着物探技术不断发展,对激发源特性也提出新的要求。为了适应地震勘探新技术的要求,一方面需要继续研究传统液压可控震源结构和工作机理,以期改善、提高震源信号品质;另一方面需要另辟蹊径,将一些成熟的通用振动技术应用于可控震源上,开发出新型地震激发源设备。将电磁振动技术所具有的信号频带宽、输出畸变小、有效输出力大等优势应用于可控震源,有望改善震源信号特性,这将是可控震源领域新的研究方向之一。
Up to now,conventional vibrators are still main equipment on the seismic exploration. The continual development of exploring technology also appeals to the vibrator for new demands. Adapting to new exploring demands,on the one hand the scientists should continually study the vibrator's mechanism to improve the capabilities,on the other hand the scientists hope to transplant the mature electromagnetism vibrating technologies to vibrator and excogitate new vibrator. The new vibrator has the advantages of the electromagnetism signal such as wider frequency bandwidth,lower distortion,and greater effective output. This will be the new research direction of the future vibrator.
