摘要:
鄂尔多斯盆地东南部的铜川-黄陵地区是中国油页岩资源最丰富的地区之一,其中三叠系延长组是盆地内最具资源潜力的油页岩产出层位。为了认识和评价该区三叠系延长组长7油页岩矿床特征、资源品级和勘探远景,在油页岩地质调查、钻探、测井解释和样品分析的基础上,研究认为:①该区延长组长7油页岩分布稳定、厚度较大,主要油页岩矿层段集中,便于开发利用; ②油页岩品质中级、发热量较高、灰分中等、湿度低、硫分高; 由于油页岩产气率较高,且干馏气可用作工业燃料,应将其作为一种伴生资源进行综合评价和利用; ③半深湖—深湖相与浅湖过渡带及湖湾环境是油页岩形成的最有利相带; 长7地层中发育多层火山凝灰岩,富营养的火山灰促进了生物的繁盛,推动了长7优质油页岩的大规模发育; ④区内仅500 m以浅的长7油页岩资源量达1 346.46×108 t,干馏油页岩油资源量为63.70×108 t,资源潜力巨大。油页岩资源品质良好,具有大型—特大型油页岩矿床远景。
Abstract:
Tongchuan-huangling area in southeastern Ordos basin is one of the regions that have the most abundant oil shale resources in China.Triassic Yanchang formation is considered as the greatest potential layer for oil shale exploration.In this article,geological survey,drilling logging interpretation and sample analysis of oil shale in Triassic Chang 7 were done to better understand the deposit characteristics,grade quality and exploration prospect,providing a reference for further oil shale exploration in the study area.Results are as follows: ①The oil shale in Triassic Chang 7 is thick,concentrated and distributed stably,facilitating the utilization.②The oil shale has medium grade,high calorific value,medium ash content,low humidity,and high sulfur content.Besides,the oil shale has a high gas production rate,making it possible to be an industrial fuel.③The most favorable facies zone for the formation of oil shale were the transition zone between semi-deep ~ deep lake facies,shallow lake facies and bay environment.The eutrophic multilayer tuff in Chang 7 promoted the thriving of organisms,which was the foundation of the widespread high quality oil shale in Chang 7.④The oil shale resource of Chang 7 above 500 m is up to 1 346.46×108 t,in which the oil resource produced by retorting is up to 63.70×108 t.The oil shale in the study area has a good quality,providing a prospect of large-outsize oil shale deposit.
