复杂山地地震采集接收技术探讨
|
摘要
川东砂泥岩区属于高信噪比地区,勘探目标以岩性-构造复合圈闭为主,对地震资料的要求为高能宽频。针对南方山地复杂的地表条件,从干扰波的特点入手,提出了基于压制高频噪音的检波器组合方式,以及基于提高与大地耦合程度的检波器耦合技术,从而确定适合南方山地的检波器组合和耦合方式,有效的提高了地震资料的有效频带。
The sand shale area in east of Sichuan province is a high signal-to-noise area.The main exploration aim is litho structural combination traps.The seismic data is high in energy and broad band.For the complex condition of South Mountain and the characteristics of the interference wave;a Geo-phone combinative method is introduced based on controlling high frequency noise.The combination and coupling methods of the Geo-phone suitable in the South Mountain area are determined to improve technology of a Geo-phone coupling with the ground.It turns out that this technology help to improve the valid frequency band of the seismic data.
