【摘要】：目前,国际上对天然气水合物产状、分布和特征的认识已取得显著进展,开展了一系列陆地多年冻土区和海域天然气水合物试采,但天然气水合物开采仍面临科学挑战。本文在综述全球天然气水合物勘探开发现状的基础上,阐述了天然气水合物储层分类及其开采的地质控制因素,提出了海域天然气水合物有效经济开采面临的资源评价、开采技术方法、储层地质参数和工程地质风险等4方面的科学挑战。要实现海域天然气水合物的有效经济开采,资源评价是基础,开采技术方法是关键。判定天然气水合物储层是否可采需要精确的储层地质参数,能否实现有效开采取决于工程地质风险的控制。
[Abstract]:At present, significant progress has been made in international understanding of the occurrence, distribution and characteristics of natural gas hydrates, and a series of gas hydrate production tests have been carried out in permafrost and sea areas on land. However, the exploitation of natural gas hydrate is still facing scientific challenges. Based on the review of the present situation of gas hydrate exploration and development in the world, the classification of natural gas hydrate reservoir and the geological control factors for its exploitation are expounded in this paper. This paper puts forward four scientific challenges for the effective economic exploitation of natural gas hydrate in the sea area, such as resource evaluation, mining technology, reservoir geological parameters and engineering geological risk, and so on, in order to realize the effective economic exploitation of natural gas hydrate in the sea area. Resource evaluation is the foundation and mining technique is the key. To determine whether the gas hydrate reservoir is recoverable or not requires accurate reservoir geological parameters and whether it can be effectively exploited depends on the control of engineering geological risk.
