摘要
通过地震弱反射信号的分析研究获得地球深部精细构造,增强深部资源勘探能力,是目前地球物理学研究的热点之一.胜利探区在高精度地震资料后续处理过程中逐步发现,目前地震资料数据难以满足当前微幅构造、砂砾岩体等复杂地质体调查的需要.本文通过在胜利探区高精度地震采集过程中开展各种接收方法试验,对检波器二次串并联、接收点位、组合基距等不同接收方式开展研究,初步归纳形成一套提高弱反射信号的接收方法.研究结果表明,该技术方法记录信噪比高、能量强,可有效拓宽地震资料频宽、增强弱反射信号接收能力.
Using weak reflected signals to study the earth deep fine structure and enhance the deep exploration is one of the hotspots in geophysical research now.From the high precision seismic data processing in Shengli exploration area,it is gradually found that the seismic data is difficult to meet the need of the current complex geological bodies survey, such as micro-structure and sand gravel body survey.Therefore,in this paper,we carried out the tests in Shengli exploration area by various ways, and dealt with the receivers' secondary series-parallel connection methods research, initially formed a set of improving the weak reflected signals method.The results of the study show that:this technology method has the ability to broad the seismic data bandwidth and effectively heighten weak reflected signal reception.
