摘要
三维地震为油气工业的增储上产作出了重大贡献， 随着采集处理成本的不断降低， 周期的不断缩短， 全三维处理和叠前深度偏移等技术的推广应用， 以及计算机技术的迅速发展，全三维地震解释已成为国内外致力发展的技术． 国外一些有实力的软件公司相继推出了一批这方面的应用软件， 如 Ｌａｎｄｍａｒｋ 的３ Ｄ Ｖ Ｉ、 Ｖｏｘ Ｃｕｂｅ ， Ｇｅｏ Ｑｕｅｓｔ 的 Ｇｅｏ Ｖｉｚ， Ｐｒａｄｇｍ 的 Ｖｏｘｅｌ Ｇｅｏ等等， 它们在油气勘探和开发中推广得到了应用． 其技术主要包括空间区域自动追踪、面块切片、 Ｖｏｘｅｌ、相干体和三维可视化技术． 目前的全三维解释重点放在构造解释上， 很少涉及储层参数和流体性质方面的储层解释， 技术尚处于发展的初期， 诸如地震属性技术、三维空间断层的识别、提取和显示。
D seismic survey has made a great contribution to the increment of reserve and producing rate in oil and gas industry. With the decreasement of the cost of acquisition and processing,shortening of cycle time,application and dissemination of full 3D processing and prestack depth migration techniques,and rapid development of computer technology,full 3D seismic interpretation has become a technology to which major efforts have been devoted. Some powerful software companies abroad have developed out a batch of application software in succession,such as 3DVI and VoxCube of Landmark,GeoViz of GeoQuest,and VoxelGeo of Paradigm. These software has been applied and disseminated in hydrocarbon exploration and development. The techniques include spatial automatic tracking,surfaceslice,voxel,coherency cube and 3D visualization. At present,the stress of full 3D seismic interpretation is structural interpretation,rarely involving reservoir interpretation for reservoir parameters and fluid properties,and the techniques are still at the initial phase of development. Many techniques remain to be further developed and perfected,for example,seismic attribute technique,identification,extraction and display of faults in 3D space,automatic division and extraction of subarea.
