涡北河网区三维地震采集技术

3D seismic collection of the district of drainage network in Wobei

涡北勘探区属于河网地带 ,难以进行正常的地震施工。为此 ,本文提出了一种以规则束状观测为基础和特殊观测系统相结合的数据采集方法。该方法适应了这种复杂的地表条件 ,获得了“空白区”的地震资料 ,为今后类似地表条件地区的三维地震勘探提供了经验。

Wobei exploration district is a drainage network area, it is hard to carry out seismic construction. Therefore, this paper has suggested a kind of data collection's method with regular bundle form observation as the basic method and special observation . The method is suitable for complex surface conditions. The seismic information of“blank area”have been gotten, and some experience in the 3D seismic exploration under the similar condition have been gained using this method.
