摘　　要：垦东北部新近系馆陶组上段(简称馆上段)油气富集程度高,是该区主要的含油层系。针对馆上段四砂组内部储层发育情况,根据研究区储层测、录井资料,总结了三种砂体沉积模式(单河道模式、双河道叠置模式、多河道叠置模式),精细解剖砂体的叠置特征是进一步挖潜的重点。通过近道集叠加、分频重构、地层切片融合以及瞬时振幅属性技术,对多期叠置河道开展储层描述研究,落实了河道形态展布以及砂体厚度分布,对有利储层发育区进行有效预测。The upper Ng of Northern KD has a high degree of oil and gas enrichment.Therefore,it is the main oil-bearing strata in this area.Based on lithology logging and cores,it was summarized three modes of sandbody deposition:single channel,double channel superposition,and multi-channel superposition.Finely dissecting the superposition characteristics of sandbodies is the key to further explore the potential.By using near-channel stacking,frequency division reconstruction,stratigraphic slice fusion,and instantaneous amplitude attribute technology,it was carried out studies on reservoir description of the multi-stage superimposed channel.The distribution of channel morphology and sandbody thickness have been implemented,and the favorable reservoir development areas have been effectively predicted.
