摘　　要：深入分析传统深水气井测试管柱内天然气水合物在管壁上沉积是造成管柱堵塞的主要原因,文中提出了一种将多层次决策(ADM)和灰色关联技术相结合的混合多准则决策(MCDM)评估方法,通过熵权关联法(GC-TOPSIS)计算与理想天然气化合物数据信息评估的相似度来抉择最佳绿色防治评估。利用层次分析法(AHP)确定了防治建立的分层指标结构的权重向量,经实验结果证明,本研究方法应用效果好。In-depth analysis of natural gas hydrate deposition on the tubing wall in the conventional deepwater gas well test column is the main cause of column blockage.The best green control assessment was chosen.The weight vectors of the hierarchical index structure established by control were determined using hierarchical analysis(AHP),and the experimental results proved that this research method was applied well.
