摘要
朝阳盆地是松辽外围盆地,勘探认识程度不高,一直未做系统评价。通过资料收集、野外地质勘探、样品采集和测试分析,确定了朝阳盆地油页岩的岩石矿物学特征、有机地球化学特征和工业品质特征。初步查明朝阳盆地油页岩主要为中低品质、低发热量、高灰分油页岩,含油率介于3.50%~7.70%;有机质类型为Ⅰ-Ⅱ1型;九佛堂组垂向上共发育3个矿组,以二矿组厚度大,矿层横向上连续性较差,平面上不易对比;矿层厚度与品质变化也较大。研究成果揭示了朝阳盆地油页岩的垂向、平面分布特征及富集规律,为松辽外围朝阳盆地油页岩勘探开发有利目标优选提供地质依据。
Chaoyang basin is a basin outside Songliao basin,and the exploration awareness is not high,so systematic evaluation has not been done.Through data collection,field geological exploration,sample collection,and test analysis,the petromineralogical characteristics,organic geochemical characteristics and industrial quality characteristics of the oil shale in the Chaoyang basin have been determined.It is preliminarily identified that the oil shale in the Chaoyang basin is mainly low-quality,low-calorie,high-ash oil shale,with an oil content of 3.50%-7.70%;the organic matter type isⅠ-Ⅱ1.There are three ore groups in the vertical direction of the Jiufotang formation.The thickness of theⅡore group is large,the lateral continuity of the ore layer is poor,and it is not easy to compare on the plane;the thickness and quality of the ore layer also vary greatly.The research results reveal the vertical and horizontal distribution characteristics and enrichment rules of the oil shale in the Chaoyang basin,and provide a geological basis for the optimization of favorable targets for the oil shale exploration and development in the Chaoyang basin outside Songliao basin.
