摘要
为了进一步扩展并深化南堡4号构造浅层岩性地层油气藏勘探目标,针对该区明化镇组河道砂体定性或定量描述所面临的地质问题和技术问题,以富油气凹陷岩性油气藏勘探理论为指导,综合应用GeoEast解释系统中的预测技术及其他配套技术,针对性地提出了由宏观到微观、逐步控制、逐级逼近的地震识别预测思路,识别并评价了南堡4号构造明化镇组河道砂体,证实可以进一步提高河道砂体预测的精度,为该区的岩性地层圈闭勘探指明目标,亦为其他地区开展类似研究工作提供借鉴。
In order to further explore shallow targets in Structure No.4,Nanpu area,we discuss in the paper geological problems of qualitative or quantitative channel description in Minghuazhen Formation.Interpretation tools provided by GeoEast system are applied to seismic data in the area under the guidance of the exploration theories of lithostratigraphic hydrocarbon reservoir in enriched depressions.Seismic identification and prediction from macroscopic to microscopic observation,step control and step approximation are adopted.The shallow channel sand identification has been well enhanced based on the study results.Minghuazhen Formation in Structure No.4 is identified and evaluated.The favorable targets of stratigraphic-lithologic traps are indicated in this area,and also provides a reference for similar areas.
