摘要: 对国内外生物礁油气勘探状况进行了评述,并对有关生物礁勘探技术的方法也作了简要讨论.中国西部克拉通盆地寻找大油田的情况表明,塔里木盆地塔中地区奥陶系是生物礁型油田的主要勘探方向,寒武系的盐下及白云岩储层中的油气值得关注;鄂尔多斯盆地奥陶系生物礁天然气勘探尚须重视,特别要注意基底断裂与生物礁分布的相互关系以及礁体的封盖条件.生物礁—白云岩(储集层)—膏盐(盖层)的模式是寻找生物礁油气藏的关键,我国应重视对生物礁油气藏的勘探,这是中国西部地区下古生界(及震旦系)碳酸盐岩寻找大油气田的最好的靶区.

Abstract: The exploration status of reef oil-gas fields at home and abroad was concerned. The exploration methods and technology of reef oilfields were discussed.The founding of giant oil-gas fields in the craton basin of West China shows that the Ordovician of Tazhong area in Tarim Basin is the major exploration target for reef type of oilfields,the Cambrian oils beneath the salt-rocks and in the good dolomite reservoirs are also expected to be found.Natural gas exploration of the Ordovician reefs in Ordos Basin is the best potential.Especially the relation between basement faults and reef distribution needs to be studied.The Ordovician of Tarim Basin and Ordos Basin as well as the Sinian of Sichuan Basin are the best prospect for reef exploration.The model of reef-dolomite-gypsum-salt is the key for searching reef pools.The reef pool is the best target of oil-gas exploration of the lower Paleozoic(and Sinian) in West China.

Key words: Tarim Basin, Ordos Basin, petroleum exploration, Lower Paleozoic, reef, reservoir-formation pattern
