| Abstract: | We have designed an efficient and practical synchronous parallel algorithm for the distributed system. We have realized the parallelization of 3-D post-stack depth migration software on SP2 with PVM, and gained ideal parallel efficiency and scalability. After applying the software to the complex geological structures such as buried hills in zhuangxi area of Shengli oil field, on the migration sections which we have achieved, the events are properly positioned, and the fault plane is clear to see. The migrated images are reasonable with the geological interpretation and coincide with the real drilling results very well after checking. |
