天然气水合物勘探与开采进展

PROGRESS IN EXPLORATION AND PRODUCTION OF GAS HYDRATE

目前,天然气水合物以能量密度高、储量大和分布广等特点,被公认为是21世纪的重要后续能源。各国纷纷加大天然气水合物勘探和开发的研究力度。现有天然气水合物开采方法主要有注热开采法和非注热开采法两种,都不同程度地存在一些问题。本文在对现有开采方法优缺点进行分析的基础上,对注热开采天然气水合物方法进行了重点阐述,分析了采用注热开采方法的几种不同形式,为经济有效的开采天然气水合物提供依据。

At present,featured by high energy density,large reserves and wide distribution,gas hydrate is acknowledged as an important follow-up energy in 21 century.In many countries,great efforts have been made to strengthen the research on exploration and development of gas hydrate.For gas hydrate producing,both heat injection and non-heat injection are the two main methods.But there exists some problems.Based on analysis of the advantages and disadvantages of the methods,this paper describes emphatically heat injection method,and analyzes its different forms.That provides a basis for producing gas hydrate economically and effectively.
