摘　　要：埕东凸起北坡上古生界二叠系发育高角度的地层不整合油藏,油藏的形成与分布主要受不整合面与储层控制。直井钻探发现的油层少,经济效益低,需要钻探水平井进行勘探。文中系统分析了二叠系的储层特征及油气成藏条件,总结了油藏的分布规律与控制因素,建立了完善的油气成藏模式,对指导二叠系地层不整合油藏的勘探具有重要意义。There are high angle unconformity reservoirs in the Permian in the North Slope of Chengdong Salient. Drilling vertical well only find a few oil layers,its economic benefit is very low, so that it is necessary to drill horizontal well to explore. The paper systemicly analyse reservoir characteristics and reservoir-forming condition in the Permian in the North Slope of Chengdong Salient, summarize the distributing rule and control factor, and establish comparatively perfect reservoir-forming model. The model has the important significance to guide the exploration of unconformity reservoir in the Permian.
