摘　　要：在对东濮凹陷南部地区深层气藏盖层室内试验的基础上 ,分析了盖层的物性特征———孔隙度、渗透率和突破压力等 ,研究了突破压力随地区、层位和埋藏深度的变化规律 ,对盖层突破压力进行了综合评价 ,定量研究了该区盖层突破压力的平面变化规律 。On the basis of lab experiment of caprock samples of deep gas reservoir in the south of Dongpu depression, the physical properam.ties such as porosity, permeability and breakthrough pressure are analyzed, a change of breakthrough pressure with position, horizon and buried depth is studied, comprehensive evaluation is performed on the caprock breakthrough pressure, a plane changing rule of the caprock breakthrough pressure is quantitatively studied in the area, by which indispensable data are provided to search for an effective gas reservoir in the area.
