摘　　要：周知物源分析是地质研究的基石,加之开发地质研究逐渐精细,因此有必要选定更适宜开发阶段的分析尺度,对物源分析重新梳理。本文利用重矿物分析,以涠洲11-X油田流一段富砂的高水位体系域为目标,以五级层序为尺度,结合7个油田32口井的重矿物资料开展研究。结果表明:层段纵向上分3个五级层序,共受到3个物源补给形成。Provenance analysis is the basis of geological research,as well as the development research gradually refined.Therefore,it is necessary to select appropriate provenance research scale in development,and re-combing the method.Based on the analysis of heavy minerals combined with the data of 32 wells in seven oil fields,the high water level system tract in member 1 of Liushagang Formation in Weizhou 11-X oil field is taken as the target area under the fifth order sequence.The results show that the target is vertically divided into three fifth-order sequences,which are supplied by three provenances.
