摘　　要：多年的勘探实践表明,太行山山前拗陷带的冀中拗陷、冀南地区和汤阴断陷是以下第三系和石炭一二叠系为烃源岩的"新生古储"和"古新混生古储"型潜山油气藏为主体的复式油气聚集区。近年来冀中拗陷进入深潜山勘探阶段,应用重、磁、电、震全信息地球物理地质勘探技术在冀中东北部又发现了10个古潜山,已钻探了5个,其中2个潜山获商业气流,2个获低产气流;在霸县凹陷及廊固凹陷分别发现了兴隆宫北和固安两个大型"新生古储"潜山。本文论述了已获低产气流、以石炭-二叠系煤系为主要烃源岩的码头和韩村潜山的气藏规模和兴隆宫北、固安二个大型"新生古储"潜山存在的地质地球物理依据及其含油前景,并就进一步认识和落实上述古潜山的油气勘探问题提出了相应的建议。笔者认为,此区有可能成为出奇制胜形成战略突破的勘探战场。Many years'prospecting practice showed that Jizhong depression, Jinan area and Tangyin fault depression of Taihangshan piedmont depression are complex oil/gas accumulational zone where the source rocks are in Palaeogene and CarboniferousPermian and main body of reservoirs are buried-hill reservoirs taking the form of 'source in young formation and reservoir in old formation' and 'source both in young and in old formation and reservoir in old formation'. The Jidong depression has been in the epoch of deep buried-hill exploration in recent years, 10 paleo-buried-hills are discovered in the northeast of Jidong by using gravimetric, magnetic , electric and seismic exploration data and 5 buried-hills have been drilled, among which 2 buried-hills have gained industrial gas stream and 2 buried-hills have obtained low-productivity gas stream; Large-scale buried-hills of 'source in young formation and reservoir in old formation'Xinglonggongbei and Gu'an buried hills have been discovered separately in Baxian depression and Lang-Gu depression. The paper expounded the size of gas reservoirs of Matou and Hancun buried-hills that have gained low-productivity gas stream and their source rocks mainly are Carboniferous-Permian coal measures, put forward the geologic and geophysical bases why did these two large-scale buried - hills of ' source in young formation and reservoir in old formation'-Xinglonggongbei and Gu'an buried hills exist and their oil-bearing prospect and proposed corresponding suggestion on the oil/gas exploration issues how to further know and define above mentioned paleo-buried-hills. The authors considered that the region could become exploration battlefield achieved strategic breakthrough and surprised success.
