摘　　要：在石油地震勘探中,采用三维联片处理技术,对以往三维地震资料进行联片重复处理是近几年地震资料处理挖潜方式之一。联片处理中采用统一定义观测系统,对不同三维进行子波处理与时差、振幅、频率、相位的校正,然后在三维地表一致性条件约束下进行全三维处理,得到相对保持振幅处理的高品质地震资料。通过两个实例的研究应用,在重复处理的基础上,发现了石南21井岩性油气藏和莫10井油气藏。The technology of three-dimensional(3D) block-tie reprocessing for old 3D seismic data is one of the means of improving the potential of seismic data processing in oil seismic prospecting in recent years.In the block-tie processing,observation system of uniform definition is adopted to process wavelet and to correct moveout,amplitude,frequency and phase for different 3D blocks,in the end,all 3D blocks will be processed together under the control of surface-consistency.After these,the high quality seismic data keeping relative amplitude can be gained.With the help of the technology,Well Shinan-21 lithologic pool and Well Mo-10 pool have been found successively.
