二维叠前深度偏移处理方法研究

Study on 2-D Pre-stack Depth Migration Processing Methods

摘要: 当今，石油勘探对地下构造成像精度的要求越来越高。本文对二维叠前深度偏移处理方法进行了研究，确定了处理流程，并对处理效果进行了分析。通过本方法处理的叠前深度偏移剖面与叠后时间低移剖面对比可知，剖面品质有较大改善、成像质量得到提高，具有很好的实用价值。

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.
