| 摘 要： | 以东营凹陷胜北断层下降盘坨76块沙四上亚段扇三角洲沉积体为例,对扇三角洲沉积体系下的高精度层序地层学进行了研究。经过分析认为,在扇三角洲沉积体系中的高精度层序地层单元划分为准层序组、准层序、层组、层四级,并对准层序和层组的类型和对比方法进行了总结。将扇三角洲沉积体系中的层组类型划分为Fu、Cu和Cu-Fu三大类,准层序类型划分为Fu-Fu、Cu-Fu、Cu-Cu三大类,同时总结出了沿物源方向的相序递变和垂直物源方向的侵蚀切割对比2种准层序和层组对比模式。

| Abstract: | This paper discusses high-resolution sequence in fan-delta sedmentary system, exemplifying T76 fan-delta of the fourth upper member of Shhejie formation in Shengbei fault's downthrown side of Dongying depression.Research shows that the high resolution sequence stratigraphic units are divided into parasequence set,parasequence,bed set and bed in fan-delta. The authors particularly study types and comparative methods of parasequence and bed set. The type of bed set is divided into Fu,Cu and Cu-Fu types, and parasequence into Fu-Fu,Cu-Fu and Cu-Cu types. We have summrized two comparative methods of parasequence and bed set which are facies change paralleling to source area and incisement perpendicular to the source area. |
