The basin has multiple reservoir-seal combination, reservoir bed distributed in the formations from Carboniferous to Tertiary. 從石炭系火成巖至第三系各個(gè)層位都有儲(chǔ)層發(fā)育，具有多套生儲(chǔ)蓋組郃；
Taking Meishan group in Nanhai Basin as an example, this paper analyses the control action of regional seal to the formation of gas reservior. 以瓊東南盆地梅山組蓋層爲(wèi)例，進(jìn)行了區(qū)域性蓋層對(duì)天然氣藏形成過(guò)程中控制作用的分析。
A shallow lake facies is developed in Neogene Minghuazhen and Guantao Formation, making Bozhong Sag the best area of Neogene reservoir seal combination in North China Basin; 渤中坳陷上第三系明化鎮(zhèn)組與館陶組發(fā)育淺湖相沉積，是華北含油氣盆地上第三系儲(chǔ)蓋組郃最佳的地區(qū)；
