运城盆地地层与构造特征
|
摘要
为进一步了解运城盆地地层发育,利用钻井、测井、物探资料,对该区地层分布、构造特征、断裂发育进行了分析和研究。结果表明,沉积地层主要为中晚元古界、下古生界、古近系、新近系和第四系,缺失上古生界地层。地层沉积相按照时间顺序为中晚元古代海相碎屑岩沉积、早古生代海相碳酸盐岩沉积、晚古生代海陆过渡沉积和中、新生界河流-湖泊沉积。运城盆地分为孤峰山隆起、运城坳陷和中条山断隆3个一级构造单元。运城坳陷又可进一步划分为栲栳塬断凸、永济凹陷、鸣条岗断凸、涑水河谷地堑、青龙河谷地堑和绛县断凹6个二级构造单元。运城盆地主要发育控制着断陷盆地内的沉积建造和边界的中条山北缘断裂及双泉-临猗断裂,还有栲栳塬东侧断裂、黄河谷地东侧断裂和鸣条岗南北侧断裂等。
In order to further understand the formation development and the characteristics of oil and gas in yuncheng basin,the formation distribution,reservoir petrological characteristics,reservoir physical properties and reservoir space were summarized and analyzed by using core,thin slice,well logging and reservoir physical properties data.The results show that the sedimentary strata are mainly middle and late proterozoic,lower Paleozoic,paleogene,neogene and quaternary,and the upper Paleozoic strata are missing.Stratigraphic sedimentary facies are chronologically divided into middle and late proterozoic Marine clastic rocks,early Paleozoic Marine carbonate rocks,late Paleozoic Marine and continental transitional sediments and middle and Cenozoic fluvial and lacustrine sediments.Yuncheng basin is divided into three first-order tectonic units: gufengshan uplift,yuncheng depression and zhongtiaoshan uplift.Yuncheng depression can be further divided into six secondary tectonic units: kaolaoyuanfault bulge,yongji depression,mingtiagang fault bulge,su shui valley graben,qinglong river valley graben and jiangxian fault depression.Yuncheng basin maily develops zhongtiaoshan and shuangquan-linyi which control the sedimentary construction and boundary of the rift basin, also kaolaoyuan eastern faul、Fault on the east side of the Yellow River valley、south and north side of mingtiaogang fault.
