摘要
在进行500～1000m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。
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.
