摘要
以往基于水平层状介质的常规观测系统设计方法,已不能满足如今高精度油气勘探的要求。基于此,宜采用基于地震波照明度的观测系统优化设计方法,然而目前的照明分析技术还仅限于对观测系统进行评价。本文在地震照明模拟的基础上,通过探究检波器接收能量和接收效率之间的关系,形成基于检波器接收照明能量效率最大化的最大炮检距设计方法。其基本思路是在目标部位通过模拟放炮,建立接收能量和接收效率之间的优化关系,并获取最佳最大炮检距。通过对取自实际资料的断陷模型和逆掩推覆模型的模拟实验,证明基于照明度分析的观测系统参数设计方法具有良好应用效果。
The geometry design based on horizontal layers in the past cannot meet today's needs of seismic exploration.Recent illumination for geometry optimization is limited for geometry evaluation.In this article,we propose a new idea of maximum offset design based on maximize illumination energy efficiency.According to relationship analysis between received energy and receiving efficiency,we find the maximum offset by maximizing receiver illumination energy efficiency.Simulating shooting on a geological model with targets,we build an optimizing and compromising connection between received energy and receiving efficiency and obtain optimal maximum offset.The experiment on a geological model and model with fault depression and overthrust built from a work area shows that this illumination geometry design approach gets better results.
