The east section of the south slope of the Dongying Sag is rich in oil and gas resources, with diverse reservoir types and complex physical properties of crude oil. It has typical characteristics of multi-source and multi-stage accumulation. The classification of crude oil types is the basis of petroleum geology research. By analyzing the content and distribution characteristics of trace elements in typical crude oil samples, combined with mathematical statistics, the effective classification of crude oil types in the study area is realized. The content of alkali metals, alkaline earth metals and transition metal elements in crude oil is significantly higher than that of rare earth elements, and the content of light rare earth elements is higher than that of heavy rare earth elements. There is a good correlation between the total amount of trace elements and the bulk composition of crude oil, while the correlation between the total amount of rare earth elements and the bulk composition of crude oil is relatively poor. The cluster analysis of multiple trace element-related parameters can classify the crude oil into three types, and the biomarker parameters of different type crude oils show obvious differences, indicating that the use of trace elements to classify crude oil types is effective and feasible in the study area. This study shows that the content, distribution characteristics and related parameters of trace elements in crude oil can be used as effective oil source correlation tools, reasonable selection of correlation parameters, and comprehensive analysis of cluster analysis methods can accurately classify the types of crude oil.
