苏北盆地新生代侵入岩分布特征及地质意义
|
摘要
岩芯观察和薄片鉴定表明,苏北盆地新生代侵入岩主要为辉绿岩,少量煌斑岩,具有明显不同于沉积岩的岩矿、测井响应和地震剖面特征。以钻井和测井的统计资料为基础,利用三维地震资料的解释结果,总结出苏北盆地新生代侵入岩分布特征:纵向分布层位以古新统阜宁组为主,其次为始新统三垛组和戴南组,单层厚度一般几米至几十米,有顺层侵入、穿层侵入和沿断面侵入三种产出形式;平面分布面积超过1000km2,以高邮凹陷和金湖凹陷分布广,呈碟状或串珠状分布。苏北盆地新生代侵入岩分布与深大断裂有关,同时对油气成藏具有重要的影响,是值得重视的研究领域之一。
It is concluded by drill cores observation and thin sections identification that the intrusive rocks in the North Jiangsu Basin are mainly composed of diabase and few lamprophyre,whose mineral and lithological features,logging response and seismic reflection characteristics are obviously different from sedimentary rocks. Based on statistical data of drilling and logging,combined with result of 3D seismic data interpretation,the distribution of intrusive rocks have the following characteristics:(1) vertically,the most important horizon is the Paleocene Funing Formation,secondly,the Eocene Sanduo and Dainan Formation;(2) the thickness of a single layer is generally from several meters to several dozens meters;(3) there are three intrusive types,including bedding intrusion,cut-bedding intrusion and along fault intrusion;(4) horizontally,the distribution area of the intrusive rocks is more than 1000 km2,which are widespread in the Gaoyou sag and the Jinhu sag with the shape of dish or string of beads. In the North Jiangsu basin,the distribution of Cenozoic intrusive rocks are related to deep faults,meanwhile,the intrusive rocks have important influence on reservoir accumulation. It is worth to pay more attention to study the Cenozoic intrusive rocks in the North Jiangsu basin.
