采用特殊物探施工方法解决复杂地形条件下的数据采集

The construction method of solving special geophysical data acquisition under complicated terrain

本文介绍了在村庄、鱼塘内采用小井深、小药量施工激发获得有效波三维地震资料,经过处理获得很好地三维偏移数据体,能够很好的解释断层、褶曲、陷落柱、煤层露头及煤层冲刷或沉缺等地质构造现象。并通过钻探验证与场区的地震解释能够达到很好的吻合,说明采用小井深、小药量技术方案对类似复杂地形条件下的数据采集具有很好的借鉴意义,值的大力推广。

The paper introduces a method using small well depth and the less charge shot array to obtain effective wave3 D seismic prospecting data in the village and fish ponds. After processing to obtain 3- D migration data,can be a very good explanation of the fault,fold,subsided column,outcrop of coal seam and coal seam scouring or sedimentary gap geological phenomenon. The result well coincide with the drilling test and field seismic interpretation It shows that the technology scheme using small well depth and the less charge has a good reference to similar data collected under complex terrain conditions,vigorously promote the value.
