【摘要】：冀中坳陷饶阳凹陷等富油凹陷剩余资源依然丰富,但勘探程度已经很高,规模储量发现难度越来越大,构建全凹陷整体连片高品质二次三维地震数据平台,是富油凹陷二次勘探整体构造研究、整体沉积体系研究和地震储层预测、精细目标落实进而实现二次勘探突破的必然要求。文章提出了富油凹陷二次三维地震勘探的"采集优化、城区突破、连片处理、目标融合"工作思路,并构建了冀中坳陷上万平方千米的整体地震数据平台,为冀中坳陷富油凹陷二次勘探持续突破、规模增储发挥了关键作用。富油凹陷整体连片二次三维地震勘探的思路和技术对类似地区的勘探研究也具有借鉴意义。
[Abstract]:The remaining resources of oil-rich sag such as Raoyang sag in Jizhong depression are still rich, but the exploration degree is already very high, and the discovery of scale reserves is becoming more and more difficult. It is the study of the whole structure, the whole sedimentary system and the prediction of seismic reservoir in the secondary exploration of the rich oil sag. The paper puts forward the idea of "acquisition optimization, urban breakthrough, continuous processing and target fusion" for the secondary 3D seismic exploration in the rich oil sag. The whole seismic data platform of tens of thousands square kilometers in Jizhong Depression is constructed, which is a continuous breakthrough for the secondary exploration of oil-rich depression in Jizhong Depression. The idea and technology of the whole connected segment secondary and three-dimensional seismic exploration in the oil-rich sag also have reference significance for the exploration research in similar areas.

【正文快照】： 冀中坳陷剩余油气资源总体规模依然较大,仍具有较大勘探潜力,其中富油凹陷是剩余油气资源的主体,但富油凹陷的勘探程度亦已很高,规模油气储量的发现难度越来越大,华北油田曾一度进入了含油面积仅0.2km2、储量规模仅8×104t的“小数点”勘探阶段[1]。自20世纪80年代,冀中坳陷就
