地震观测系统是用来表示激发点、接收点和地下反射点三者之间的位置关系。观测系统决定地震采集资料的质量,其质量直接影响后续的处理解释结果和精度,关系到地震勘探的成败,可见观测系统的重要性。本文基于地震观测系统设计的基本理论,从基本原则、参数选择出发,讨论了如何合理设计海上二维地震观测系统。 Seismic observation system is used to represent the excitation point, the receiving point and the underground reflection point of the relationship between the three. The quality of the data collected by the seismic acquisition system is determined by the observing system. The quality of the data directly affects the interpretation and accuracy of subsequent interpretation and interpretation of the seismic exploration, which shows the importance of the observation system. Based on the basic theory of seismic observation system design, this paper discusses how to rationally design offshore two-dimensional seismic observation system based on the basic principles and parameter selection.
