通常情况下常规观测系统主要考虑的是覆盖次数问题,对于地震勘探来说这还是远远不够.我们不仅要考虑覆盖次数问题,还要考虑很多其他问题,比如地表的复杂性、观测系统的方位角、偏移距、炮检距等问题,这就要求我们用软件直观的显示出来.最近几年有人提出砖墙式观测系统,本文结合某勘探区三维地震勘探实例分别对砖墙式观测系统和常规线束状观测系统进行了观测系统设计对比,通过对其方位角、炮检距等问题的分析,得出砖墙式观测系统在方位角、炮检距等方面明显要优于常规线束状观测系统,这为观测系统优化设计提供了依据.
Usually, the main consideration of conventional observation systems is the coverage problem, which is not enough for seismic exploration. We should not only consider the coverage problem, but also consider many other issues, such as the complexity of the ground surface, the orientation of the observation system Angle, offset, offset and other issues, which requires us to use the software visually displayed in recent years someone put forward the brick wall observation system, combined with a three-dimensional seismic exploration exploration area were brick wall observation system Compared with the conventional wire harness observing system, the design of the observing system is compared. Through the analysis of the azimuth, offset and other issues, it is concluded that the brick wall observing system is obviously superior to the conventional wire harness in azimuth and offset distance Observation system, which provides the basis for the optimization design of observation system.
