摘要

 The analysis of sediment source is an important part of basin research,and it plays animportant role in favorable reservoir prediction and oil exploration.The parent rocks from differentprovenances and the difference of sedimentary environment caused differences in the micro characteristicsof sediment components from different provenances.The authors choose the characteristic elements andheavy minerals content of the middle part of Third Member of Shahejie Formation in deposit of Minfengdepression as a sample,study the provenance system by the clustering analysis.First,based on theoptimization of the trait element ratios,the scope of each provenance system was accurately defined byQ-mode cluster analysis for trait element ratios;Second,the types of parent rock was recovered by R-mode cluster analysis for heavy minerals content.The study shows that the main zone of depression wasinfluenced by the delta of Yonganzhen in Qingtuozi area and the delta of Dongying in the south.Theanalysis result was consistent with sedimentology features,indicate this method could be used effectively in estimating source direction of sediment.
