针对海外某区块三个已发现油藏无论是储层砂体规模还是储层物性均存在较强的非均质性的地质特点,以该区块A油藏为例,详细阐述了定量评价静态地质模型不确定性的技术流程和研究方法,包括关键不确定性变量分析、实验设计、储量风险评价以及模型优选,为类似油气田静态模型不确定性评价提供了一定的借鉴意义.

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.
