摘要
水敏性稠油油藏开发方式优选是稠油开发过程中一个重要而又难度较大的环节,在确定优选评价因素、评分标准、各因素权重、模糊关系矩阵R的基础上,建立了稠油开发方式优选的二级模糊综合评判数学模型,针对草4块中等水敏性稠油油藏特征,通过模糊变换计算得出稠油冷采综合评判结果为0.125,稠油热采结果为0.625,稠油冷采的效果一般,而用热采效果较好.这对该区块油藏的开发方案的制定具有一定的指导意义.
The measurement optimization is an important part of in heavy oil and watersensitive reservoir development, on the basis of determining the element of assessment, grading standards, the weight of the factors, fuzzy relationship matrix R, the fuzzy comprehensive analysis in measurement optimization modle in heavy oil and Water-Sensitive reservoir is establislaed. Aimed at the CAO-4 heavy oil water-sensitivity reservoir characteristics,by calculating,cold production results 0. 125,thermal recovery results 0. 625. The result shows thermal recovery is better than cold production,the conclusion give some guidance to CAO-4 measurement optimization.
