Abstract:

Hierarchic analysis method used in sedimentary facies quantitative recognition can improve the analytic accuracy and correction of sedimentary facies.The facies markers that are used in determining facies types are characterited by typical hierarchic properties.These properties could be used as important quantitative indexes(weight).Combining with Fuzzy comprehensive evaluation,hierarchic analysis method could be used to recognize facies types.A quantitative recognation example of Permian marine carbonate facies in Jingshan section of Central Hubei Depression suggests that this method is effective and the correct ratio is up to 78%～88%.
