采用自主开发的海上二维多分量地震资料处理系统,对南海某构造采集的二维多分量地震勘探资料中的一条测线进行了试验处理。处理中,针对该构造资料转换波静校正难度大、气云区转换波不易成像等难题,采取了相应的处理手段和措施。通过对各种参数效果的比较和分析,确定了合适的处理流程和参数。结果表明,在“气烟囱”模糊带处得到了较好的转换波成像剖面。

A 2D multicomponent seismic line was processed tentatively by CNOOC with self-developed multi-component seismic data processing system. To cope with the problems of statics and converted wave imaging over gas cloud area, several measures are adopted. In data processing practice, processing parameters and flow are determined and refined by trial and error. Desired converted wave images have been achieved over gas cloud area.
