中国海域天然气水合物勘探研究新进展
|
摘要
天然气水合物是中国未来最具潜力的新型替代能源。中国的天然气水合物资源量巨大,自中国开展天然气水合物勘探研究工作的17年来,中国在海域天然气水合物勘探研究方面取得了7个方面的进展,特别是2007年5月,中国地质调查局在南海神狐海域钻获近海底天然气水合物沉积样品,这是中国天然气水合物勘探上的一个重大突破。但是,中国海域天然气水合物的勘探研究还存在5个方面的主要问题:海域天然气水合物资源量预测过大;对天然气水合物成藏动力学、成藏体系研究不够,尤其是对烃源研究不够;中国在天然气水合物沉积层岩石物理方面的研究几乎还是空白;对地震剖面上的BSR、振幅空白带与天然气水合物沉积层的关系仍然不是十分清楚;中国目前的天然气水合物勘探技术研究还不够深入、不够系统。指出了中国天然气水合物勘探的光明前景。
China has to face up with the increasingly serious energy crisis and natural gas hydrate will be hopefully the most potential alternative energy source in near future.Since there is rich natural gas hydrate resource in China,seven aspects of achievements have been obtained after 17 years of researches and development on this new energy,especially in May of 2007,the sedimentary samples of natural gas hydrate was acquired at the bottom of Shenhu sea area in South China Sea by Chinese Geological Bureau,which was an important breakthrough in exploration history of natural gas hydrate.However,in this field of study in China there still exists five points of issues as follows:(1) the forecast of natural gas hydrate resource at the sea is exaggerated;(2) studies on hydrate reservoiring dynamics,reservoiring system,and especially the hydrocarbon source are not enough as well;(3) research on physical stratigraphy of hydrate sedimentary reservoir rocks is still blank;(4) the relationships among the BSR in the seismic profile,blind zone of amplitude,and sedimentary reservoir are still unknown;(5) the exploration technical studies are not complete and systematic yet.In the end,this paper pointed out bright future for China to keep on its further exploration and development of natural gas hydrate.
