【摘要】 天然气水合物因其巨大的能源意义成为近年来研究的热点。从成因特征、赋存特征、物理化学特征和地球物理特征4个方面系统地论述了冻土区天然气水合物的基本特征。中国冻土区主要包括青海祁连山及可可西里—风火山—乌丽冻土区、西藏羌塘地区和东北漠河地区等远景区。根据现有研究,各冻土区天然气水合物资源量丰富,然而冻土区气候和环境条件制约着天然气水合物研究工作进展,应在加大水合物理论研究的同时开展水合物识别技术、钻采工艺研究,早日由寻找、勘探阶段进入开发钻采阶段。更多还原

【Abstract】 Gas hydrate becomes a hot spot by its huge meaning to energy.This paper discusses its basic features in genesis,distribution,physics and chemistry,and geophysics.China’s permafrost zone includes Qinghai’s Qilian mountain,Kekexili-Fenghuo mountain-Wuli,Tibet’s Qiangtang area and Mohe area,where are abundant in natural gas hydrate resources,but limited by climates and environment from researching.A theoretical study is proposed in identification and mining so as to enter the mining stage from prospecting and exploration.更多还原
