摘　　要：随着油田勘探开发工作的不断深入,对地震成像的精度要求越来越高。成像方法从传统的克希霍夫叠前偏移方法转向精度更高的波动方程算法,而波动方程算法对输入地震资料的要求较为苛刻。在分析常规数据规则化方法特点的基础上,提出了基于DMO与反DMO的数据规则化方法,满足了叠前波动方程成像条件的要求。With the deep development of oilfield exploration and development,the demand on the seismic imaging accuracy was higher.The imaging was converted to wave equation method from conventional Kirchhoff prestack migration method.The wave equation method was more accurate and had more requirements on seismic information input relatively.By analyzing the features of conventional data regularization method,a data regularization method based on DMO and inverse DMO is presented and studied in this article,which can satisfy the imaging conditions of prestack wave equation method.
