Application of Quantitative Method for Evaluation the Uncertainty of Static Model

In view of the strong heterogeneity of both reservoir sandstone distribution and reservoir physical property of three oil reservoirs in one overseas oil field,the quantitative evaluation method has been used to evaluate the uncertainty of static model for one oil reservoir(A reservoir) of this oil field,and specific technical process has been discussed,including analysis of the key uncertainty variables,experimental design,OOIP risk evaluation and model selection.This paper can provide some reference for analyzing the uncertainty of static model in the similar oil fields.
