Abstract:

Hierarchy analysis in reservoir researches is a new methodology including hierarchy characterization and hierarchy modelling.The method made good use of stratigraphy,se-dimentology,event geology and structural geology as theoritical grounds,outcrop,recentsediment survey,flume experiment,seismic stratigraphy,sequence stratigraphy,log in-terpretation,formation test as means,and modern geomathematics,computor modelling as tools to do hierarchy analysis.The analysis process inreservoirs can be done by deter-mination,description,interpretation,modelling and combination of hierarchy.
