Study On The Sedimentary Microfacies And The Servitor Characteristic Of XinLi Oil-field

In this paper,the research and development has conducted on the main sedimentary microfacies and small layer sand body in Xinli oilfield,and the V block was dissected mainly,including the second digital logging data processing and the reservoir comprehensive evaluation research.On the basis of core observation,the key coring wells were analysised,according to various types of sedimentary facies marks,the types of the sedimentary facies,subfacies and microfacies were determined.Using the small layer as a unit,the database of sand layer thickness and the reservoir thickness were established,and the sand body figure was drew,and the morphology of the sand body and lateral continuity were studied.On the basis of the optimal selection of reservoir evaluation parameters,applying cluster analysis and discriminant analysis method,the reservoir evaluation was made on,and the longitudinal and plane distribution laws were researched.The research methods and results in this article provided theory basis for guiding other oilfield development indexes,With the new technology and new approaches in xinli oilfield,the study of the current reservoir has carried on,system,comprehensive integration and dynamic in Fuyang layer,and it has important guiding meaning and extension.
