海上二维地震观测系统的设计原则

Principle of Design Observation System of Marine 2D Seismic

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。

The seismic observation system is used to express the relationship among the shot point, the receiving point, and the reflection point. The quality of acquisition data is decided by the observation system, and which directly affect the quality and accuracy of subsequent processing and interpretation. SO the good or not of observation system is related to the success or failure of the seismic exploration, it is very important. This article based on the basic theories of observation system, we discuss how to design observation system of 2D marine seismic with the basic principles and parameters.
