| 摘 要： | 渤海蓬莱A构造主体上大面积浅层气形成屏蔽效应,致使地震成像不能准确反应地下地质构造特征。为此,在多波地震试验的基础上,在该构造上实施了海上三维四分量地震勘探及二维四分量地震采集。考虑到转换波处理的特殊性,在处理时特别注意了共转换点(CCP)道集的生成、水平分量方位角旋转等主要环节,从而得到了较好的转换波剖面。

| Abstract: | Because of the screening effect formed by large area low-layer gas above the Penglai A structure,Bohai Bay,the seismic imaging can not correctly reflect the features of subsurface geologic structure.Therefore,on the basis of multiwave seismic tests,an offshore 3D four-component(4-c) seismic exploration and an offshore 2D four-component(4-c) seismic acquisition were performed above the structure.Having considered the particularity in converted-wave processing we pay much attention to main links such as the generation of CCP trace gather,the azimuth angle rotation of horizontal component etc.,and better converted-wave profiles have been obtained. |

| Keywords: | multiwave seismic survey converted-wave CCP trace gather "gas chimney" |
