复杂地表条件下的煤田地震数据采集技术研究

在煤田地震勘探中,由于复杂地表地形条件的限制,使野外的数据采集成为难点,寻找一个适合野外的地震数据采集方法成为关键。本文结合煤田三维地震勘探过程中所遇到的复杂地表条件,通过试验对比选择良好的激发、接收条件,应用非线性观测系统等技术措施,来保证野外地震记录的质量,取得了高品质的野外地震记录,为地震数据的处理与解释奠定了基础。

The reseach on the acquisition technology of coal seisimic exploration in complicated surface condition

It is difficulty to acquit the seismic data in the coal seismic exploration because of the limitations of the complicated surface.The key is to find an appropriate acquisition technology of seismic data.This paper analysis complicated surface basied on the coal 3-d seismic exploration.We select the suitable excitation and receiving conditions by testing and apply many technical measures such as non-linear surveillance systems for the quality of the seismic records.We get the high-grad seismic records by applying those that will help the next steps such as the seismic data processing and the seismic explanation.
