Study on 2-D Pre-stack Depth Migration Processing Methods
-
Abstract
Higher requirements are put forward for the accuracyof subsurface structure mapping technology as seismics develop. This paper discusses the necessity for applying pre-stack depth migration technology, studies processing methods, determines processing procedure and analyzes processing results. Comparison between post - stack andpre -stack depth migration sections shows that the qualityof the latter is higher and mapping quality is improved.
