【摘要】 本文提出一种模型无关、基于均匀地下介质与水平反射层的采集脚印定量分析方法.该方法无需进行费时的三维地震波模拟,以解析的方式直接计算出各种不同观测系统炮检点分布下地震波振幅能量分布情况,进而实现对整个地震观测系统的采集脚印的定量评价.该方法物理意义明确,理论公式简单,能够实现观测系统采集脚印的快速定量分析,从而直观对比各种待选观测系统设计方案的预期采集脚印情况,为观测系统的设计增加了一项新的依据.更多还原

【Abstract】 We present a velocity model independent method predicting acquisition footprint of 3D seismic survey based on the homogeneous media and the horizontal reflection layers.It analyzes the distribution of the seismic energy at each bin which leads to the quantitative analysis of acquisition footprint.By making use of this approach,we can quantitatively calculate acquisition footprints of different seismic acquisition schemes and choose the optimal one.更多还原
