摘　　要：科学、合理设计的三维观测系统优化设计可减轻大量的、不必要的工作量,减少在勘探方面的经费开支,也是取全、取好地震资料的前提。激发点自动避障预设计方法和药量设计方法,在一定程度和部分环节上提高了观测系统优化设计精度,能够快速、科学、合理地完成设计方案,先设计后放样,将设计前移,精准指导地震采集各个施工工序,保证了炮检点分布均匀、激发能量均匀。该方法为地表复杂区三维地震勘探的大规模开展提供了有效的方案,能够提高工作效率、减少施工成本,增加安全系数,提高资料品质。Optimization design of a scientific and reasonable 3D observation system can reduce a lot of unnecessary workload and expenditures on exploration.It is also a prerequisite for obtaining complete and good seismic data.The dose design method and pre-design method of trigger point automatic obstacle avoidance are proposed,which can improve the optimization design accuracy of the observation system to a certain extent and in some links,and can complete the design plan quickly,scientifically,and reasonably.After designing and lofting,the design is moved forward,and each construction process of seismic acquisition is accurately guided to ensure that the inspection points are evenly distributed and the excitation energy is even.This method provides an effective solution for the large-scale development of 3D seismic exploration in complex surface areas,which can improve work efficiency,reduce operation costs,increase safety factors,and improve data quality.
