摘　　要：通过对松辽盆地陆西凹陷绍根地区煤田钻探和测井资料进行研究,发现该区存在大量伽马异常信息。工作区大部分钻孔放射性异常与煤田资料有较好的对应性:原位验证孔与煤田孔的自然伽马异常曲线形态基本一致、异常峰值位置基本吻合、原位验证孔与煤田孔的异常厚度相似。根据煤田自然伽马测井和岩心测试,认为绍根地区存在四方台组砂岩型和嫩江组泥岩型两种类型工业铀矿体。研究结果显示,绍根地区具备良好的铀成矿条件和找矿远景,且仍有大部分潜在铀矿孔未进行施工验证,建议开展进一步的铀矿勘查工作。Through the study of drilling and logging data in the Shaogen area of the Luxi Sag in the Songliao Basin,it is found that there is a large amount of gamma anomaly information in the area.Most of the radioactive anomalies in the drilling holes in the work area correspond well with the coalfield data:the natural gamma anomaly curve shape of the in-situ verification holes is basically consistent with that of the coalfield holes,the position of the anomaly peak is basically consistent,and the anomaly thickness of the in-situ verification holes is similar to that of the coalfield holes.Based on natural gamma logging and core testing in the coalfield,it is believed that there are two types of industrial uranium deposits in the Shaogen area:the sandstone type of the Sifangtai Formation and the mudstone type of the Nenjiang Formation.The research results show that the Shaogen area has good uranium mineralization conditions and prospecting prospects,and there are still most potential uranium ore holes that have not been verified through construction.It is recommended to carry out further uranium exploration work.
