The careful observations of core data,logging and 3D-seismic and petrographic analysis reveal that the 2nd member of the Shahejie Formation in the Dawangbei Sag consists of sandy beach and bar of shallow water over-lake.
通过岩心精细的观察,结合测井、三维地震以及岩石鉴定分析等资料的综合研究发现,大王北洼陷沙二段盆地断坳期为浅水漫湖砂质滩坝沉积,可分为:滩、坝主体、坝侧缘、坝间4种沉积微相,其中坝主体的成分成熟度和结构成熟度较高,且坝主体砂层最厚,滩、坝侧缘和坝间砂体次之。

针对东营凹陷沙四上亚段滨浅湖滩坝砂体沉积特征,根据层序地层学理论,在综合分析地震、测井、岩心等资料的基础上,采用地震层序、声波时差和测井曲线叠合等方法进行层序界面识别,建立了东营凹陷沙四上亚段层序地层格架,将沙四上亚段划分为一个三级层序,并根据层序内低位体系域、湖侵体系域及高位体系域发育情况,细分为7个准层序组。

| 概 述 |
| 普卡基湖坝建在新西兰坎特伯里区、普卡基(Pukaki)河上，在蒂马鲁市附近。工程目的是发电。大坝建在冰川成因的砾石、砂和粉砂层上，为碾压土坝，最大坝高61m，坝顶长823m，大坝上、下游坝壳采用冰水砾石建成，中央心墙和上游铺盖则采用取自终碛的碾压粉砂砾石。通过上游铺盖和下游排水井阻截地下渗流。大坝体积460万m3。在大坝以西约300m处建有1座单独的副坝，为普卡基渠引水建筑物，副坝为碾压土坝，坝高32m，坝顶长640m，体积125万m3。横剖面与主坝类似。普卡基湖面积174km2，最高运行水位530.7m，水位变幅14m，总库容63亿m3。渠道进水口为170m长的钢筋混凝土箱形涵洞结构，分3孔，每孔宽6.1m，高9.1m。涵洞上游侧设有闸门室，安装3扇5.9m×6.1m(高×宽)的弧形闸门来调节渠道的流量，进水口最大流量为560m3/s。普卡基渠全长12km，最终与怀奥渠汇合。陡槽式溢洪道位于大坝左坝肩处，设4扇弧形堰顶闸门，闸门尺寸为13.0m×10.7m(高×宽)，陡槽长400m，下游设消力池，溢洪道泄流量3398m3/s。导流涵洞位于右岸，是座椭圆形断面的钢筋混凝土结构，高10m，宽6m，长360m。涵洞上游侧设有闸门室，安装1扇9.0m×6.0m(高×宽)的弧形闸门。闸门用于调节湖水位上升期间的流量，相当于1个泄水底孔。工作水头57m，泄流能力570m3/s。大坝于1976建成。 |
