【摘要】 热带雨林地区地震采集施工有其特殊性,三维观测系统的选择应重点考虑地质任务的需要和实际施工的可行性。为此,对目前在西非中部热带雨林地区普遍使用的两种观测系统,在系统属性、采集资料的品质、施工难度和效率几方面进行对比分析,找出各自的优缺点,提出了在该类地区选择三维观测系统时应该考虑的几个关键因素。更多还原

【Abstract】 In the light of the speciality of seismic acquisition in tropic rain forest,the choice of 3-D geometry should mainly consider the geological task and possibility of operation. From the analyses of geometry attribution,seismic records,operation efficiency and difficulty of the two 3-D geometries currently used in the tropic rain forest of middle West Africa,the advantages and disadvantages of them were sorted out. Some key factors for the choice of 3-D geometry in similar area were suggested.更多还原
