    摘要
  • 地震谱反演是近年发展起来的一种新的地震方法,可利用地震数据构建反射系数剖面,极大地提高地震资料的分辨率。利用谱反演方法对南海神狐海域天然气水合物赋存区的地震资料进行了处理,获得该区海底地层的反射系数剖面,结合BSR和测井资料,确定了该区天然气水合物储集层的顶界和底界,从而圈定了该区天然气水合物储集层。
    Spectral inversion, as a new method for seismic inversion, has well developed in recent years. It may construct the reflection coefficient profile for improving the resolution of the seismic data. We used the method in this study with both the synthetic and real seismic data. Results show that the method is efficient and may produce good results. Drilling has confirmed that there are natural gas hydrate reservoirs in the Shenhu area of South China Sea. We applied the method to the seismic data acquired from the area and produced the reflection coefficient profile, which represents the seabed stratigraphy. With the BSR in both the seismic profile and logging data, the top and bottom reflections of the natural gas hydrate reservoir were delineated in the reflection coefficient profile.
