【摘要】 在进行500~1 000 m以浅地层的勘探中,高分辨率地震勘探技术是十分经济有效的地质勘探方法,它较二维常规地震勘探具更高的地层分辨率,可识别出常规地震方法无法反映的薄层状地层、小构造及年轻的新构造痕迹,具有二维地震无法替代的作用。根据本系统多年来在海上高分辨率地震勘探中的经验,结合有关理论,总结整理出了高分辨率地震勘探中需要重视的技术问题,并介绍了一些运用高分辨率地震勘探获得的地质成果,可为浅部地质勘探提供参考。更多还原

【Abstract】 High-resolution exploration is a more economic and effective way in the exploration of 500～1 000 meters’ shallow strata.The resolution of strata obtained from high-resolution seismic exploration is higher than routine 2D seismic exploration.High-resolution seismic is able to distinguish the thin stratum,small structure and young tectonic feature and is irreplaceable by 2D seismic exploration.According to the long working experiences about high-resolution exploration from No.1 Marine Geological Investigation Party,Shanghai Offshore Petroleum Bureau,this paper sums up some important technical experiences of high-resolution seismic exploration on the basis of some theories of high-resolution seismic exploration,and introduces some geological examples of application to indicate that exploring technique is an crucial factor to obtain ideal geological results.更多还原
