摘要：

在系统总结海洋天然气水合物形成的物质来源及成因机理、物理化学响应、形成环境及成藏模式、分布规律和资源评价进展的基础上，提出了我国开展天然气水合物成藏机理研究的方向和科学问题。2007年4—6月通过钻探获得了测井、原位测量、沉积物岩心及其顶空气、孔隙水、微生物、水合物等样品和资料。南海北部陆坡神狐海域是研究天然气水合物成藏机理和分布规律的理想区域。采用重点分析天然气水合物成藏的物质基础、形成环境、成藏过程、响应机理和成藏系统等研究思路，针对天然气水合物成藏系统中气—水—沉积物—水合物体系的相互作用机理、天然气水合物成藏过程中的物理化学响应机理、天然气水合物成藏要素的耦合控矿机理等3个关键科学问题，开展天然气水合物成藏物源、地质与温压场等成藏条件、成藏演化热动力学机理、成藏响应机理和天然气水合物成藏系统等5个方面研究。

Abstract:

Based on the summary of research progress on gas sources and formation mechanisms, geophysical and geochemical proxies, formation environments and geological models, distribution of marine gas hydrate, this paper points out and discusses the direction and scientific issues for formation mechanism research of marine gas hydrate in China.Many scientific data and samples such as the wire-line logging, in-situ temperature, properties, geochemical data and sediment cores, pore water, head space and void gas, microbiology samples, etc,were obtained through the gas hydrate drilling expedition in Shenhu area of the north slope of South China Sea in April-June 2007. So,Shenhu area is an ideal area for the research on formation mechanism and distribution pattern of marine gas hydrate. Focusing on the material basis, formation environment and process, responding index and formation system of gas hydrate, a series of research in the light of the interaction between gas, water, sediment and gas hydrate, geophysical and geochemical responding mechanism, coupling control of different conditions for gas hydrate formation should be carried out on the north slope of South China Sea.

Key words: gas hydrate system, formation mechanism, geophysical and geochemical proxy, accumulation model
