【摘要】 高升潜山主要为中上元古界时期潜山,其上房身泡组发育了巨厚玄武岩。在地层结构深入认识基础上,利用地震反射特征、不整合面识别等技术对元古界潜山顶面识别追踪,建立全区速度场、采用变速成图等技术方法,准确落实潜山构造形态,深化了对潜山格局的认识,整体构造面貌为一鼻状古隆起,并被多期断层切割形成了多种类型的潜山圈闭;通过油源分析认为高升潜山油品性质与曙光潜山油品性质相近,饱和烃色、质谱特征与陈家洼陷沙四段烃源岩具亲源关系,其油气主要来自陈家洼陷;储层为元古界大红峪组石英岩,储集空间为构造和溶蚀缝洞;通过洼陷深部的供油窗口或经断层不整合面运移至潜山内部成藏。其成藏主要受圈闭、油源及储集性能的控制。更多还原

【Abstract】 Gaosheng Burial Hill is mainly upper and middle Proterozoic group,whose upper foam chamber developed thick basalt.With a deep understanding of its stratum structure,the author applies seismic reflection technology and unconformity recognition technology to identify and track the top surface of proterozoic burial hill.Through building velocity in the whole area and using variable-velocity mapping technique,the author has affirmed its structural feature and deepened the understanding of its pattern-nose-shape palaeohigh with various kinds of buried-hill traps due to multi-episode fault cutting.Analysis of oil source concludes that oil property of Gaosheng Burial Hill is close to that of Shuguang Burial Hill and its color and mass spectrum signature of saturated hydrocarbon have a pro-source relationship with source rocks of Member Sha 4 in Chenjia Depression from which come most of oil and gas in Gaosheng Burial Hill,that its reservoir is quartzite of proterozoic Dahongyu member and reservoir space is Structure and denudation seam hole and that its hydrocarbon accumulation is controlled by trap,oil source and reservoir property.更多还原
