摘　　要：针对南海北部边缘盆地复杂的地质情况,提出了切片技术应用的新思路:时间切片与相干体相结合解决莺歌海盆地底辟带的塌陷区和模糊区等特殊的地质体问题;沿层切片与地震属性信息融合落实琼东南盆地断层、河道和异常体边界;地层切片与地震反演波阻抗体组合研究琼东南盆地储集体的沉积演化过程。切片技术应用的新思路已在南海北部边缘盆地勘探中成功实施,很好地解决了实际生产中遇到的复杂地质问题。Aiming at the complex geology in the marginal basins along the northern South China Sea, some new ideas to apply the slice technique was proposed： to solve the problem of particular geological bodies, such as collapse zones and fuzzy zones of the diapir area in Yinggehai basin, by combining time slices with coherence cube; to i- dentify faults, fluvial channels and abnormal body boundaries in Qiongdongnan basin by integrating horizon slices with seismic attributes; to study the depositional evolution of reservoir bodies in the basin by combining stratal slices and impedance bodies of seismic inversion. These ideas have been successfully implemented in the marginal basins a- long the northern South China Sea, with some complex geological problems in actual exploration been effectively solved.
