鄂尔多斯盆地姬塬地区非纵三维地震勘探采集技术
|
摘要
黄土塬区非纵三维地震勘探采集技术源于常规非纵地震勘探方法,并借鉴了三维地震勘探中非纵观测能够避开部分干扰波的技术优点。本文论述在鄂尔多斯盆地姬塬地区黄土塬非纵三维地震勘探项目实施过程中,以非纵地震技术为基础,针对探区地质目标特征进行非纵三维观测系统设计和论证,通过基于山地微测井表层结构调查的激发因素设计,并利用该设计的非纵三维观测系统完成了地震数据采集,获得了高质量三维数据体,促进了该区的油气勘探开发。
Off-line 3D seismic acquisition,developed on off-line 2D seismic,has advantages of suppressing noise.This paper discusses an off-line 3D seismic acquisition in Jiyuan loess area,Erdos Basin.Source parameters are optimized based on near surface investigation by uphole.Geological target oriented off-line 3D geometry is designed and testified.High quality 3D data cube obtained by our off-line 3D seismic acquisition shows not only its effectivity,but also oil exploration prospect in this area.
