摘　　要：天然气水合物由于其巨大的资源量而受到广泛关注,我国也在海域和冻土区开展了天然气水台物勘探工作,并同时在实验室开展了相关研究。然而,目前天然气水合物勘探工作还面临着诸多难题。通过概括我国在南海神狐海域、珠江口盆地东部海域、青海祁连山冻土区天然气水合物钻探情况,以及总结我国天然气水合物实验技术、勘查技术取得的进展及其应用情况,分析了这3个区域的天然气水合物赋存类型及其成藏富集方式,并对钻探结果与钻前研究预测结果进行了对比分析。分析结果表明,这3个钻探区域的天然气水合物赋存类型存在较大的差异,显示出不同的成藏富集方式,勘查预测结果与实际钻探结果也存在着一定的出入,显示出天然气水合物成藏的复杂性及天然气水合物勘查技术的不成熟性。开展天然气水合物勘探目标预测评价和"甜点区"优选技术攻关,确定适合商业开采的天然气水合物富集区域,并进行开发技术试验,将有利于推进我国天然气水合物勘探及研究进展。Natural gas hydrate is attracted widespread attention owe to its huge amount of resources. China has also been carried out gas hydrate exploration work both in the offshore and permafrost area, and carried out some research in the laboratory at the same time. However, Natural gas hydrate exploration is currently facing many challenges. Through summarizing the gas hydrate drilling conditions of the Shenhu of South China Sea, the east waters of the Pearl River Mouth Basin, Qinghai Qilian Mountain permafrost area, and summarizing the progress got and its application of gas hydrate experimental techniques and exploration technology, this paper analyzes the reservoir types of the three gas hydrate regions and its accumulation enrichment methods respectively, and makes a comparative analysis on drilling results and pre-drilling study ＆ prediction. The results show that the gas hydrate reservoir types of these three drilling regions exist a greater difference, showing different enrichment patterns, and besides, survey predicted results and actual drilling results are some discrepancies, which shows that the accumulation complexity of natural gas hydrate reservoir and the immaturity of natural gas hydrate exploration technology. Carry out the gas hydrate exploration target prediction evaluation and ＂sweet-area＂ preferred technology research, identify suitable commercial exploitation area of gas hydrate accumulation, and pilot development technology, which will be beneficial to propel research and exploration progress of natural gas hydrate.
