Abstract:3D pre-stack Kirchhoff depth migration is one of important means for petroleum prospecting. During the imaging processing, it needs a large of ray travel time data. How to optimize the obtaining the required ray travel time data is very important to the efficiency of parallel processing the pre-stack depth migration. In this paper, in order to solve the problem of how effectively to obtain the required ray travel time, we advance one multi-level data acquisition and exchange strategy by enhancing the reusabili… Show more
