摘　　要：在复杂地表区进行地震采集施工十分困难,主要表现为地表障碍造成的空炮或空道形成剖面缺口及对目的层有效覆盖次数、地震资料品质的影响。在地震采集野外现场设计中,本着安全、质量、超前(设计)、技术、成本等"五大意识",把握好工区全信息收集的各个环节,并根据障碍物的特殊情况,以尽可能减少恢复放炮距离、剖面缺口及炮点分布均匀为原则,灵活运用纵横向变观方法,有效地降低了地震采集复杂困难地表对施工质量的影响,保证了资料品质。It is hard to carry out seismic acquisition in the complex surface area because the surfaee barrier could affect target layer＇s degree of effective covering and ,seismic data quality. In field spot design for seismic acquisition, it is necessary to master each part of perfect information acquisition in the work area based on five consciousnesses of safety, quality, advance design, technology and cost and use properly vertical and horizontal observation method according to barriers＇ properties and following the principle of balanced shot point distribution to effectively reduce the impact of complex surface on seismic acquisition operation and ensure data quality.
