摘　　要：针对传统模糊综合评判法在压裂酸化选井实际应用中暴露出的不足,采用相对优属度矩阵、模糊层次分析法及非线性模糊矩阵合成算子,改进了模糊综合评价模型。改进的模糊综合评价模型可综合考虑各因素的影响并权衡技术、经济等指标,求取压裂井层的优属度。改进模型的评价结果与实际相符,具有评价优势,可为现场优选压裂方案及优选压裂酸化井层提供理论依据。Traditional fuzzy comprehensive evaluation method has some defects in fracture acidizing well and layer selection,therefore is improved by using optimal membership degree matrix,fuzzy analytic hierarchy process and non-linear fuzzy matrix composite operator.The modified model can take account of influencing factors,weigh technical and economical indices,and solve the optimal membership degree of fracturing well and layer.The result of the modified model coincides with the actual practice,can provide theoretical basis for optimization of fracturing scheme and fracture acidizing well and layer.
