| 摘 要： | 南黄海中部隆起是南黄海盆地构造最稳定的地区之一,也是下古生界含油气远景区之一,其找油前景引起人们极大的关注。应用小波分析等方法处理南黄海重磁异常场,揭示中部隆起区结晶基底起伏特征,同时结合区域地质以及地震剖面资料,对中部隆起地层分布特征提出了几点新认识:南黄海中部隆起结晶基底的起伏特征并非"平板"一块,其平面总体轮廓可概括为"三隆两坳";受印支运动的影响,中部隆起区发育的主要地层是震旦系-下二叠统,下三叠统青龙灰岩和上二叠统龙潭煤系已基本剥蚀殆尽;下古生界沉积中心大致位于结晶基底"坳陷"部位;上古生界受火山活动和岩浆侵入的影响,分布特征是分段而不连片;中部隆起分布着火山岩,分布特征是"东强西弱"。

| Abstract: | The middle uplift of South Yellow Sea is tectonically one of the most stable areas in the basin,and it has received great concerns since its lower Paleozoic is a potential hydrocarbon-bearing prospect area.Wavelet analysis method has been used to deal with gravity and magnetic anomalies in the South Yellow Sea to obtain the crystalline basement shape of the middle uplift,and combined with regional geology and seismic section data,some new understandings on stratigraphic distribution features in the middle u... |
