| 摘 要： | 针对天然气水合物理论预测和实际产出的不一致性、各种标志或异常未与天然气水合物建立起严格的对应关系、世界范围内已知或由BSR等间接指标所指示的天然气水合物在垂直方向和水平方向上分布的不确定性,如何更好地从地质系统论角度研究天然气水合物成藏过程和分布规律,尝试提出天然气水合物成藏系统概念,分别从烃类生成体系、流体运移体系、成藏富集体系对天然气水合物成藏过程进行了初步探讨;同时运用此思路对世界上调查研究程度较高的分布区开展了天然气水合物成藏系统初步分析。 |

| Abstract: | In consideration of the discrepancy between gas hydrate theoretical prediction and its real occurrence,the inconsistent relationship between gas hydrate indicator and its existence,the irregular gas hydrate distribution law(vertically and horizontally)indicated by drilling and indirect evidence such as BSR around the world,how to strengthen studies on gas hydrate formation process and its distribution law seems practically significant in geological view.This paper attempts to bring forward the concept of gas hydrate geological system,which contains three components of gaseous hydrocarbon source sub-system,gas-bearing fluid migration sub-system and gas hydrate reservoir accumulation sub-system.In the meanwhile,some key gas hydrate geological systems are preliminarily summarized based on worldwide typical gas hydrate occurrences. |
| Keywords: | gas hydrate geological system gaseous hydrocarbon source sub-system gas-bearing fluid migration sub-system gas hydrate reservoir accumulation sub-system |
