本文基于GeoZenix处理系统结合某地区的实际地震资料，对二维叠前深度偏移流程的若干主体及非主体处理进行了有益的探讨，提出了能适应我国东部油气勘探开发的二线叠前深度偏移处理流程以及辅助处理方法，并对各处理环节在实际应用中所遇到的问题以及应采取的措施进行了详细讨论。文中内容包括精细预处理、速度─深度模型建立、二维叠前深度偏移和叠后处理。
Based on the GeoZenix processing system combined with the actual seismic data in a certain area, this paper discusses some main and non-main processes of two-dimensional prestack depth migration processes, and proposes a new method that can adapt to the second-line prestack depth bias in eastern China’s oil and gas exploration and development Shift process and auxiliary processing methods, and discussed in detail the problems encountered in the practical application of each process and the measures to be taken. The paper includes fine preprocessing, velocity-depth modeling, 2D prestack depth migration and post-stack processing.
