摘　　要：采用综合定量分析主、客观组合赋权方式,建立关键指标可变权重组合模型,并基于TOPSIS决策模型对超深层气藏效益建产进行评价。以8个超深层气藏为例,对比分析该方法与传统单一主观赋权法、客观赋权法的评价结果。结果显示,该方法可充分发挥主、客观赋权的优势,弱化单一赋权对指标权重的不利影响,其评价结果更符合已开发气藏的实际情况。A combined weight model with variable weights of key indicators is established by a comprehensive quantitative analysis of subjective and objective weighting.Based on TOPSIS decision model,the benefit construction of ultra-deep gas reservoirs is evaluated.Taking 8 ultra-deep gas reservoirs as examples,the evaluation results by using this method are compared with those of traditional single subjective weighting method and objective weighting method.The results show that this method can give full play to the advantages of subjective and objective weighting methods,and reduce the adverse influence of single weighting on indicator weights.The evaluation results are more in line with the actual situation of developed gas reservoirs.
