摘　　要：探索多物源储集砂体的物源对油气勘探与开发具有重要的意义。重矿物分析是区分不同物源体系的重要手段之一。利用泌阳凹陷下二门地区57口钻井的重矿物测试资料,采用重矿物组合类型、ZTR指数分析等方法判别了下二门地区沉积物物源方向。研究表明,下二门地区存在3支物源,分别为东部下二门物源、东南部梨树凹物源和北部侯庄物源。Researching on the multi-source reservoir sands was of great significance of oil and gas exploration.The analysis of heavy mineral was one of the important methods for distinguishing different source systems.By using the heavy mineral data of 57 well drilling in Xiaermen Area of Biyang Sag,the methods of the type of heavy mineral combination and ZTR maturity index were used to judge the sedimentary source direction in Xiaermen Area.Study result shows that three sources exist in this region,they are Houzhuang in the north(Sungang),Xiaermen in the east and Lishuwa in the southeast.
