摘　　要：为了研究岩相古地理的元素特征,根据元素地球化学理论及元素在古环境中的迁移规律,以曹妃甸区块录井、测井及沉积相资料为基础,通过元素录井分析,研究沉积相的元素分异规律,筛选出对冲积扇相、河流相、湖泊相等沉积相的敏感元素,用于进行单井、连井沉积相分析,并作出元素平面相,恢复岩相古地理环境,最终确定与测井相模式相似的元素录井沉积相模式,证明元素录井可在一定程度上恢复岩相古地理特征。In order to study the element features of lithofacies paleogeography,according to element geochemistry theories and the migration law of elements in paleo-environment,the element differentiation of sedimentary facies was studied through element logging analysis based on the mud logging,well logging and sedimentary facies data in Caofeidian Block.Sensitive elements to sedimentary facies such as alluvial fan,river facies and lacustrine facies were filtered to analyze the sedimentary facies of single well and connected wells.Elemental plane facies was made and the lithofacies paleo-environment was restored.Element logging sedimentary facies model similar to well logging facies model was finally obtained,certifying the ability of element logging to restore lithological paleogeographic features to some extent.
