摘　　要：以高分辨率层序地层学理论为指导,以野外露头、钻井岩心、测井及地震资料的综合研究为基础,研究了黄骅坳陷新近系馆陶组Ⅲ段的高分辨率层序地层特征,识别出1个长期、两个中期和若干个短期基准面旋回层序。其中短期、中期旋回都可分为向上“变深”非对称型和向上“变深”复“变浅”对称型两类。深入探讨了不同结构类型和充填样式的各级次基准面旋回层序对储层的控制作用,认为储集砂体主要发育于长期及中期基准面旋回上升的早期。High-resolution sequence stratigraphy in the 3rd member of the Neogene Guantao Formation, Huanghua depression, Hebei is explored on the basis of outcrops, well logs and seismic data. One long-term, two mid-term and several short-term base-level cyclic sequences have been distinguished, of which the mid-term and short-term cycles are shallowingtypical of the asymmetric deepening-upward sequences and symmetric deepenmg-upward and then upward＂ sequences. The reservoir bodies are developed mainly in the early stages of the long-term and mid-term baselevel rise.
