南海北部天然气水合物潜在区源岩沉积有机地球化学研究
Sedimentary organic geochemistry research of source rocks of the potential gas hydrate-bearing areas in the northern South China Sea
Abstract
天然气水合物是二十一世纪新能源,我国南海北部陆坡是天然气水合物发育的理想场所,深入研究南海北部陆坡天然气水合物成藏机制和富集规律,为我国海洋天然气水合物资源勘探和开发提供重要的理论依据和指导,具有重要的经济和科学意义。其中气源条件既是天然气水合物形成发育的物质基础,又是天然气水合物成藏的关键。本论文依托国家“973”计划子课题《南海北部天然气水合物成藏的气源条件研究》(项目编号:2009CB21951)、国家自然科学基金项目《南海北部海底沉积层硫酸盐-甲烷体系产消机制及其界面(SMI)特征研究》(项目编号:40976035)和《天然气水合物成藏体系中产甲烷与甲烷厌氧氧化作用生物标志物和分子生物... Gas hydrate, as resource of the twenty-first century, is widely developed in the northern slope of the South China Sea. Further study on gas hydrate accumulation mechanism and enrichment patterns is required, to provide an important theoretical basis and guidance for marine gas hydrate resource exploration and development. Among them, gas source condition is not only the material basis of gas hydr...
