【摘要】 四川阆中地区属丘陵向山区过渡地形,表层激发、接收条件极为复杂。在地震采集施工过程中,首先根据项目地质任务的要求,确定了合适的观测系统,即改进型砖墙式块状三维观测系统。同时在施工中,根据不同的激发和接收条件,对各施工环节采取了一系列行之有效的技术措施,确保该区获得了高品质的采集资料,为在复杂地区开展三维地震勘探资料采集工作积累了宝贵经验。更多还原

【Abstract】 Because of the landform from hill becoming to mountain in Langzhong of Sichuan, the shooting and receiving condition of the near-surface become very complex. To deal with the condition, we adopted a suitable layout at first according to the demand of the geological undertaking-one improved brick-wall 3D layout in the seismic acquisition. And then we took some effective technical measures in the data acquisition according to the different shooting and receiving condition. The high quality of the acquisition data is insured because of all these measures, which is of significance for 3D seismic acquisition in complex area.更多还原
