Abstract

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.

Key words: natural gas hydrate reservoir, hierarchy fuzzy assessment, quality evaluation
