自2008年首次发现天然气水合物以来,青海木里三露天井田的天然气水合物调查研究成为一个热点。近两年来,神华青海能源有限责任公司投资项目在三露天井田内开展天然气水合物调查评价工作,是该区最新的天然气水合物调查研究工作部署安排,目前取得了系列重要新进展。新进展主要表现为:(1)天然气水合物赋存特征研究取得了新认识;(2)对天然气水合物形成与分布的主要地质控制因素取得了新认识;(3)总结了天然气水合物成藏模式;(4)探索了地质、地球物理、地球化学、钻探等冻土区天然气水合物勘查方法,建立了钻探气测录井预判、地质标志识别、测井判识、室内鉴定等冻土区天然气水合物判定技术手段;(5)对天然气水合物资源量进行了估算并对其经济可采性进行了初步评价。综合认为,三露天天然气水合物资源目前不具备经济开采价值。
自2008年首次髮現天然氣水閤物以來,青海木裏三露天井田的天然氣水閤物調查研究成為一箇熱點。近兩年來,神華青海能源有限責任公司投資項目在三露天井田內開展天然氣水閤物調查評價工作,是該區最新的天然氣水閤物調查研究工作部署安排,目前取得瞭繫列重要新進展。新進展主要錶現為:(1)天然氣水閤物賦存特徵研究取得瞭新認識;(2)對天然氣水閤物形成與分佈的主要地質控製因素取得瞭新認識;(3)總結瞭天然氣水閤物成藏模式;(4)探索瞭地質、地毬物理、地毬化學、鑽探等凍土區天然氣水閤物勘查方法,建立瞭鑽探氣測錄井預判、地質標誌識彆、測井判識、室內鑒定等凍土區天然氣水閤物判定技術手段;(5)對天然氣水閤物資源量進行瞭估算併對其經濟可採性進行瞭初步評價。綜閤認為,三露天天然氣水閤物資源目前不具備經濟開採價值。

Since the first discovery of gas hydrate in 2008,gas hydrate survey and research has become a hot spot in Sanlutian of Muli,Qinghai.Within two years,Shenhua Qinghai Energy Development Co.Ltd.invested a project to carry out work on gas hydrate survey and evaluation in Sanlutian,which is the latest deployment and arrangement of gas hydrate survey and research in this area.At present a series of important new advances have been obtained.In this paper,these new advances are summarized:(1)new understanding on study of gas hy-drate occurrence features;(2)new understanding on main geological controlling factors on gas hydrate forma-tion and distribution;(3)gas hydrate geological formation pattern is summed up;(4)permafrost associated gas hydrate exploration methods such as geological,geophysical,geochemical and drilling methods are explored, and permafrost associated gas hydrate defining technical means such as pre-defining means by gas-logging while drilling,geological mark-recognition means,wire logging distinction means,indoor analytical identification means are established;(5)gas hydrate resource is estimated and its economical exploitation is preliminarily evaluated,which comprehensively suggests that gas hydrate resource is not economically exploitable in Sanlutian in the present.
