| 摘 要： | 作为潜在的能源储备，天然气水合物的重要性持续上升.针对天然气水合物的地震勘探也逐步由二维方式向三维方式转变.本文以单源单缆方式采集的天然气水合物三维地震数据为基础，探讨了地震数据成像的关键技术，在获得准确的三维地震成像数据体的同时，还得到三维地层速度数据体.三维地震数据更有利于描述含天然气水合物地层的地震反射特征，并刻画可能含天然气水合物地层的分布，从而拓宽对天然气水合物储层的认识.

| Abstract: | The importance of natural gas hydrate has been an ever-increasing trend due to the fact that it might be a potential future energy reserve. The seismic exploration method is of transition from 2-D to 3-D acquisition in gas hydrate investigations. Based on 3-D seismic data acquired by the single-source and single-steamer method, the key techniques of data processing were introduced and precise image of 3-D seismic data volume was obtained as well as 3-D velocity data volume of strata bearing gas hydrate. The 3-D data volume which could provide more information of gas hydrate reservoir is more advantageous than that of 2-D in depicting the characteristics and distribution of gas hydrate in strata. |
