【摘要】 通过对两个区块山地三雏地震采集技术的总结,归纳了一套适应山地三维地震采集的方法。一是通过微测井方法分步建立山地三维表层地质模型,指导动态井深设计;二是灵活的炮点与检波点布设;三是多方位的现场质量监控,确保获取高信噪比地震资料;四是合理设计观测系统,尽可能减少采集痕迹。更多还原

【Abstract】 The author has found out some 3D seismic data acquisition ways available to mountainous region by summarizing 3D seismic data acquisition technique applying in two blocks.Firstly,according to micro-log approach,mountain geologic model with 3D surface layer should be built in stages to guide dynamic well depth desiga Secondly,sourcereceiver configurations should be flexible.Thirdly,site quality should be supervised and controlled at multi-azimuth to make sure that seismic data of high s/n ratio can be collected.Finally,the design of recording geometry should be reasonable to reduce acquisition traces as much as possible.更多还原
