可控震源参数选择及在煤田勘探中的应用

Parameter Selection of Controlled Seismic Source And The Application in Coal Field Exploration

摘要:

介绍了如何选择可控震源的扫描长度和震源台数、振动次数以及扫描频宽等参数 ,指出采用数台可控震源组合 ,增加扫描的总时间和利用相关技术是提高可控震源地震资料信噪比的有效方法 ,也是可控震源取得成功的关键。

Abstract:

It has been introduced how to select the parameters of scanning length and numbers of controlled seismic source, vibration period and scanning bandwidth in this paper. The effective method to enhance the datum reliability(the ratio of information to noise)of the controlled seismic sources has been stated as adopting the combination of several sets of controlled seismic source , extending scanning period, and applying to some technologies related and this is also a key for the controlled seismic source to ma...
