| 摘 要： | 基于高分辨率层序地层学短期基准面旋回原理,通过岩心和测井曲线分析,对泌阳凹陷下二门油田核二段辫状河三角洲前缘储层砂体成因进行了研究,识别出了3 种类型7 种亚类型的短期基准面旋回结构,3种类型分别为向上变深的非对称型(A型)、向上变浅的非对称型(B型)和对称型(C型);依据短期基准面旋回结构类型及其叠加样式,7种亚类型分别对应削截式水下分流河道砂体、完整式水下分流河道砂体、叠加式河口坝砂体、河口坝-远砂坝组合砂体、河上坝砂体(C1)、河上坝砂体(C2)和坝上河砂体.研究表明,基准面升降和可容纳空间与沉积物通量比值(A/S)控制着不同成因砂体的分布.建立了泌阳凹陷下二门油田辫状河三角洲前缘储层砂体的成因分布模式.

| Abstract: | Based on the short-term base-level cycle theory of high resolution sequence stratigraphy and the data of drill core and well loggings,the paper analyses the reservoir sandstones deposited on the braided stream delta front with the 2nd member of Hetaoyuan Formation in the Xia'ermen Oilfield.On the basis of genetic,the reservoir sandstones are divided into three types of short-term base-level cycle: up-deepening non-symmetric type(mode A),up-shallowening non-symmetric type(mode B) and symmetric type(mode C)th... |
