喀左盆地油页岩资源勘探前景

摘要

阐述了喀左盆地油页岩特征,查明了资源类型及分布特征,进行了勘查目标优选,提出了该盆地勘查部署建议：喀左盆地九佛堂组一、二、三段分别发育了第1、第2、第3油页岩层群,其中矿组3-1油页岩出露点多、厚度大、认识程度高;油页岩类型主要为灰黑-棕黑色泥岩,且大部分属于中、低品级的难熔高灰分油页岩。其资源类型大部分属于预测资源量,数据表明,矿组3-1的工业意义最大,以梅勒营子凹陷分布最多。通过勘探目标优选结果,提出将该盆地分为全面系统勘探区、疏网度勘探工程实施区和专门性地质调查区的勘探部署。%Based on the field geological survey and the previous research achievements,oil shale characteristics in Kazuo basin are presented,the resources type and distribution are found out,the exploration targets selection is optimized,and then the exploration deployment suggestions are put forward.In Member No.1,No.2 and No.3 of Jiufotang formation in this basin developed first,second and third oil shale groups respectively,among which Group 3-1 oil shale appears in many outcrops,with big thickness and high control degree.The type of oil shale is mainly grey-black,brown-black mudstone,most belong to medium-low grade refractory high ash oil shale.The type of resource is predicted resource and the data show that Group 3-1 is of the greatest industrial or commercial significance,which mainly occurs in Meileyingzi sag.Based on the results of selection of oil shale exploration targets,it is suggested that Kazuo basin can be divided into all-round systematic exploration area,extensive network exploration engineering operation area and special geological survey area in terms of exploration deployment.
