摘要
Based on laboratory core test analysis,the relation between the mudstone acoustic and laboratory core test analysis of the Neogene cap rock in Raoyang sag was established. The results show that the Neogene cap rock of the study area has a medium-higher displacement pressure,good sorting coefficient and slightly fine skewness. So the Neogene cap rock has relative strong sealing ability.Neogene oil reservoir is enriched in Liuxi and Liubei area,which is adjacent to hydrocarbon generation center,source fault and high displacement pressure cap rock.Limited by the condition of cap rock,Neogene oil reservoir only scatters in Nanmazhuang area,east of Maxi sag,which is adjacent to hydrocarbon generation center and source fault too.The Huangfucun area is far away from hydrocarbon generation center and lack of source fault,although the cap rock is well,it hardly has any Neogene oil reservoir.
