The Research Of Provenance Analysis And Sand Body Distribution Of Dongying Group In South Of Nanpu Sag

Provenance analysis is an important content of ancient basin analysis and geographic analysis,it has been occupies a very important position in sedimentary basins research.More importantly,Provenance analysis has a significant influence in determining the source area of the location,nature,sediment transport paths and tectonic evolution of the entire sedimentary basin,etc.In order to further clear the exploration potential of southern source,it needs to be on the southern provenance system in the study of sedimentary,clarify its sedimentary system,the types of sedimentary facies and sand body distribution rule,it provides technical support for the next lithologic reservoir exploration target optimization.In this paper,analytical methods clastic rocks,heavy mineral analysis and seismic stratigraphy research methods and other methods are used to study provenance analysis.It adopted index changes of ZTR,characteristics of mineral assemblages,lightmieralassemblages,maturity changes and the relative percentage of sedimentary,igneous rocks and mctamorphic rocks of lithic components to clear further the source area of Dongying period in Nanpu Oilfield.In order to determine the study area rock phase,it needs to be core observation,build log phase and Single well sedimentary microfacies.Comprehensive analysis and provenance division of single well sedimentary microfacics,it makes important significance to make sure the dcpositional systems and sedimentary facies.
