中文摘要:
      以野外露头观察、岩芯观测、薄片鉴定、单井相和连井相分析等多种资料为基础,进行雄安新区雾迷山组沉积相类型划分和相分析,以及岩相古地理恢复。识别雾迷山组岩石类型和相标志,进行单井相、连井相划分与对比,以单因素分析、多因素结合等多种方法开展综合研究,恢复雾迷山组的岩相古地理,明确雾迷山组碳酸盐岩岩溶热储发育的物质基础。结果显示,雾迷山组的岩石矿物成分以白云石为主,石英次之,白云化作用显著;岩石类型多样,以白云岩为主,主要岩石类型为叠层石白云类、藻凝块白云岩、颗粒白云岩、细晶白云岩以及硅化叠层石白云岩。研究表明,雾迷山期发育于陆表海,沉积相为潮坪相,包括潮间、潮下带亚相等。
英文摘要:
      Based on the field outcrop observation, core observation, thin section identification, single well facies and connected well facies analysis and other data, the sedimentary facies types and facies analysis of the Wumishan Formation in Xiong’an New Area were divided, and the lithofacies paleogeography recovery was carried out. The rock types and facies markers of the Wumishan Formation were identified, and the division and comparison of the single well facies and connected well facies were carried out. The comprehensive study was carried out by means of single factor analysis and combination of multiple factors, so as to restore the lithofacies and paleogeography of the Wumishan Formation and clarify the material basis for the development of karst thermal reservoir in the carbonate rocks of the Wumishan Formation. The results show that dolomite is the main rock mineral composition, quartz is the second, and the dolomization is significant. The main rock types are stromatolite dolomite, algal clotting dolomite, granular dolomite, fine crystal dolomite and silicified stromatolite dolomite. According to the study, the Wumishan phase was developed in the epeiric sea, and the sedimentary facies were tidal flat facies, including intertidal and subtidal zones.
