摘要: 通过岩石薄片鉴定和岩石化学分析等手段，识别出蓬莱9-1油田潜山钻遇两套岩石组合。一是中新元古界中低级变质岩围岩，包括变质石英砂岩、石英岩、云母石英片岩等；二是花岗岩侵入体。花岗岩锆石LA-ICP-MS U-Pb定年结果显示，所测锆石206Pb/238U年龄集中于162~169 Ma，其加权平均年龄为165 Ma，该年代代表了花岗岩的形成时代，即该岩体于中侏罗世侵入到中新元古界地层。在岩矿鉴定和年代分析的基础上，通过各类岩性岩石物理特征研究，建立了该潜山带岩石的测井识别方法。分析了储层成因及控制因素，并提出了有利油气富集区带，为油气储量申报等奠定了基础。
Abstract: Through rock slice identification and chemical analysis of rock, the Penglai 9-1 oilfield and Geo- burried-hills have been considered as two sets of lithology. One set is middle-low grade meta-morphic surrounding rocks, such as metamorphic quartz sandstone, quartzite, Mica-Quartz schist in Meso-Neo Proterozoic, the other is granite intrusive. LA-ICP-MS ziron U-Pb Dating indicates that the 206Pb/238U ages of zircons from 162 - 169 Ma, weighted average 165 Ma, thus the age probably represents the formation age of the granite, indicating that the rock in the Middle Jurassic intruded into the Neoproterozoic strata. The identification method of rock in Geoburried-hills has been established by studying the physical features of rock, based on the analysis of the rock and mine identification and time analysis. We have analyzed the reasons and controlling factors of Genesis of reservoir and pointed out the best exploration area which has laid the foundation for the oil gas storage declaration and so on.
