【摘要】 天然气水合物作为一种储量巨大的后备能源,近年来已受到广泛关注。建立与天然气水合物藏开发相适应的品质评价模型是其商业开采的前提。针对天然气水合物藏的特点,在文献调研和数值模拟研究的基础上,运用多级模糊综合评判法,对影响天然气水合物藏品质的主要因素进行层次划分和权重统计,建立天然气水合物藏品质评价的多级模糊综合评判模型。最后应用该模型,对4个模拟天然气水合物藏的品质进行了分析,证实了该评价模型的适用性。更多还原

【Abstract】 Natural gas hydrate(NGH),as an alternative energy resource with huge potential,has attracted more and more attention in recent years.It is the basic work for the commercial development of natural gas hydrate reservoir to build a model to evaluate the quality of hydrate reservoir.Based on literature summarization and numerical simulation,the quality evaluation model of natural gas hydrate reservoir is built using the hierarchy fuzzy assessment,and the main parameters which influence the development effect are classified into different hierarchies and the weighting coefficients are assigned to these parameters in the assessment process.Finally,four natural gas hydrate reservoirs are analyzed which proved the validity of the evaluation model.更多还原
