| 摘 要： | 通过对地质条件的研究，将松辽盆地徐家围子断陷深层划分为沙河子组和营城组-登二段、登二段-泉一段和泉二段、沙河子组和营城组-泉一段、泉二段3个含气系统，指出这3个含气系统形成于不同时期，其形成时期和演化对天然气运聚成藏和成藏模式有控制作用，认为该区深层天然气成藏与分布的主控因素是气源、盖层、断层和不整合面。 |
| 关 键 词： | 含气系统 天然气 深层 成藏机制 徐家围子断陷 |

| Abstract: | By a study on source rocks and their space distribution characteristics,the deep layer in the Xujiaweizi fault depression is divided into three gas-bearing systems,which are K1sh+yc-K1d2,K1d2-K1q1+2 and K1sh+yc-K1q1+2.The main controlling factors of the deep gas reservoir forming are gas resource rock,cap rock,fault,and unconformity surface.Three gas-bearing systems of the Xujiaweizi fault depression are formed in different periods.There are four reservoir forming patterns.The accumulation periods and forming patterns of gas are controlled by the formation and evolvement periods of the gas-bearing systems. |
| Keywords: | Gas-bearing system Natural gas Deep layer Accumulation mechanism Xujiaweizi fault depression |
