摘　　要：鸡西盆地油页岩主要发育在虎林组和平阳镇组,其中平阳镇组的3号层是主要含矿组,为全区可采层。以油页岩样品及其化学分析数据为基础,从油页岩的矿石物理特征、地球化学指标、矿物质分析等方面对鸡西盆地永安矿区的油页岩进行了系统评价,并将含油率、灰分、挥发分、发热量等矿石工艺参数与中国其他地区的油页岩矿层进行了对比。研究认为永安矿区油页岩具有含油率较高、发热量大、挥发分、含水中等、灰分和硫等有害组分低等特征,属中低灰分、低硫富油型优质油页岩矿藏。综合考虑矿层埋深、品位特征和开采技术条件,永安矿区油页岩不适合地面干馏,最佳开发利用方式是原位开采。Hulin and Pingyang town Formations are mainly developed in the oil shale of Jixi Basin,No.3 layer in the latter is the main ore-bearing formation,and moreover has been the recoverable layer in the whole field.Based on the oil shale samples and their chemical analyzed data,the system evaluation of the field oil shale is caught out in the aspects of the mineral physical characteristics,geochemical indices,mineral analysis and so on,and furthermore the contrasts are performed between the ore technological parameters such as the oil-bearing rate,ash,volatile components,heat output and so on and those of the oil shale seam the other areas of China.The study achievements show that the oil shale in Yong'an Field is characterized by higher oil content,huger heat output,medium volatile components and water cut,and lower harmful components such as ash and sulfur,so it belongs to high-quality oil shale resources with medium-low ash,low sulfur and oil-enriched shale reservoirs.Comprehensively considering the conditions of the seam burial depth,grade characteristics,mining techniques and technologies,the oil shale in the field is not suitable for the ground dry distillation,the best way of the development and utilization is in-situ mining.
