| 摘 要： | 在研究大庆长垣以东地区深层气藏盖层空间发育特征及微观封闭能力的基础上，对其封盖能力进行了综合评价。结果认为：较好盖层的平面分布控制着天然气藏的分布；登二段泥岩盖层封闭形成时期与侏罗系气源岩的大量排烃期的匹配关系好于泉一、二段；深层气茂盖层对天然气成藏在时间和空间上均起到了控制作用。

| Abstract: | From the spatial development and micro-sealing capacity research, capping and sealing of cap formation of deep gas reservoir in eastwards Daqing placanticline was comprehensively evaluated. It is concluded that planar distribution of good quality cap formation dominates the distribution of natural gas reservoir; and the correlation between the formation period of Den 2 mudstone cap formation and significant hydrocarbon discharging period from Jurassic sourcing rock is much better than that of Quan 1 and 2. In addition, deep gas capping formation has controlling effect on the time and space of gas reservoir forming. |
