摘要

采集脚印是三维地震观测系统的固有属性,是由观测系统炮检点分布和施工方式不均匀性而产生的,严重影响采集资料振幅保真度,从而影响采集资料的处理和解释效果。通过应用三维地震观测系统采集脚印分析评价技术,定量对比分析三维观测系统不同道距、激发线距、不同排列线距、不同滚动距离、不同目的层深度等对采集脚印的影响情况,揭示了三维地震观测系统和采集脚印的内在联系,为从设计源头入手压制采集脚印、优化三维观测系统提供了手段。
Acquisition footprint is inherent in a 3D seismic observation system,which results from uneven distribution and different construction methods of shot and positioning point in the observation system,and seriously affects the fidelity of the information collection amplitude,accordingly affecting the processing and interpretation result of information collection.This article applies 3D seismic observation system footprint analysis and evaluation technology,to quantitatively compare and analyze the impact on acquisition footprint rising from changes of different trace interval,perpendicular offset,seisline interval,rolling offset of three-dimensional seismic observation system and different target stratum depth.It reveals the inherent connection between 3D seismic observation system and acquisition footprint.It provides good measures for minimizing acquisition footprint from the origin of designing 3D seismic observing system and optimizing 3D seismic observation system design.
