摘要

随着石油与天然气的持续勘探开发,地球物理勘探所面临的地质问题越来越复杂,为了提高地震勘探的分辨率与保真度,需要加密地震数据采集的空间采样密度,减小野外激发和接收组合。介绍了高密度空间采样的面元尺寸设计、观测系统设计及接收参数选取的方法和思路,展示了三维高密度空间采样地震勘探技术在我国东部地区应用的初步效果。
With the persistent exploration and development of oil and natural gas,geophysical exploration now is facing with more complex geological problems.In order to improve the resolution and fidelity of seismic exploration,we need to infill the spatial sampling density or decrease shooting and receiving array length.This paper discusses the bin size design,geometry design,and receiving parameter selection of high density spatial sampling seismic.It also presents the application of 3-D seismic with high-density spatial sampling in Eastern China.
