At the same time, the complex characteristics of underground structure make conventional stack and post-stack migration methods can not accurately imaging.
同时，由于地下复杂构造特征使得常规叠加和叠后偏移方法不能准确的成像。
With the requirment of precise seismic interpretation and thoroughgoing exploration, the conventional post-stack migration reveals its limitations.
随着勘探和开发对地震资料处理成果的要求越来越高，常规叠后时间偏移处理技术的缺陷日益显现出来。
We have realized the parallelization of 3-D post-stack depth migration software on SP2 with PVM, and gained ideal parallel efficiency and scalability.
使用PVM编程，将串行的三维叠后深度偏移软件，在SP2上实现了并行化，获得了理想的并行效率和可扩展性。
