摘要
本文通过低渗透砂岩油藏分级标准建立适用于A8区块的水驱开发效果评价体系,并采用模糊综合评价法对该区块进行开发效果评价。在模糊综合评判过程中,使用层次分析法和改进的梯形隶属度分布函数确定各个评价指标的权重和评判矩阵,经过模糊线性变换求得最终评价等级,结果表明,A8区块的水驱开发效果为"中"级。
In this paper,the water flooding development effect evaluation system suitable for the A8 block was established by the low permeability sandstone reservoir grading standard,and the development effect of the block was evaluated by the fuzzy comprehensive evaluation method.In the fuzzy comprehensive evaluation process,the analytic hierarchy process and the improved trapezoidal membership distribution function are used to determine the weights and evaluation matrices of each evaluation index,and the final evaluation level is obtained through fuzzy linear transformation.The results showed that the water flooding development effect of the A8 block is“medium”level.
