双复杂条件下高精度三维地震采集方法研究与应用——以苏北盆地高邮凹陷HM探区为例
|
摘要
苏北盆地高邮凹陷HM探区为典型的平原水网地形,人口稠密,工业发达,地震勘探资料空白带多。为此,对该区典型双复杂条件下的高精度三维地震采集方法进行了研究,结果表明:对于地面集镇和养殖场等复杂地面障碍区,采用高精度三维多震源激发技术和炮道密度控制设计技术,获取了完整的地震资料;对于火成岩区及软泥、淤泥区等复杂近地表障碍区,采用基于平面波前法原理的大基距组合激发技术和基于高密度微测井的优选激发岩性技术,提高了地震资料的品质。
HM Prospecting Region was a typical plain and network of rivers in Gaoyou Sag with a large population and developed industry,of which seismic data were insufficient.Therefore,the high accuracy 3Dacquisition method was researched in the typical double complex area.The research results indicate that the multi-source shooting and seismic shot-receiver density control design technologies are deployed for seismic acquisition in the obstacle areas,such as township and agricultural plants,and complete seismic data are obtained.In the obstacle areas of mud,ooze and volcanic rocks,the quality of seismic data is improved by the technology of array shooting with large group length before prioritizing excitation lithology.
