摘　　要：受全球新冠肺炎疫情和中低油价的持续影响,2021年全球勘探投资继续低位运行、勘探工作量有所回落,但石油公司聚焦前沿勘探领域和勘探开发重点地区,通过加深地质认识、提升圈闭识别能力,勘探成功率持续获得提升。海域勘探尤其是深水—超深水大发现不断涌现,国际石油公司包揽的跨国大—中型油气田发现主要位于“一洋一湾一海”(大西洋两岸、墨西哥湾、南里海)。通过分析深水—超深水典型油气田,总结出三方面特点:一是深耕富油气盆地,巴西盐下时隔8年再获系列油气发现;二是积累认识、战略重返,埃尼公司在科特迪瓦盆地连获油田发现;三是开发为先、拓展周边,bp在南里海再获大气田发现。针对国际石油公司开展跨国深水—超深水勘探的做法,总结出三点启示:一是超前布局,抢占有利勘探领域,灵活进退区块;二是战略跟随,不断积累经验技术,稳步提升实力;三是自主勘探,掌握关键核心技术,实现勘探创效。建议中国石油公司仍需把握一切机会,积极获取有利勘探区块,形成资源有效储备,通过“一个转变、三个加强”逐步实现“走出去”向“走上去”的跨越。Affected by the global COVID-19 and middle/low oil prices,the exploration investment has been running at a low level and the exploration workload has fallen in 2021.However,oil companies have focused on frontier exploration fields and key areas of exploration and development.Through deepening geological understanding and improving trap identification ability,the success rate of exploration has continued to be improved.Offshore exploration,especially deepwater and ultra-deepwater large discoveries,continues to emerge,and major international oil companies are responsible for the discovery of transnational giant and medium-sized oil and gas fields,which is mainly located in“one ocean,one bay and one sea”(both sides of the Atlantic Ocean,the Gulf of Mexico and the southern Caspian Sea).Through the analysis of deepwater and ultra-deepwater typical oil and gas fields,three characteristics are summarized.Firstly,by paying close attention to the oil and gas bearing basin,a series of pre-salt oil and gas discoveries were made in Brazil after an interval of eight years.Secondly,by accumulating knowledge and strategic return,Eni has successively found oil fields in the Cote d’Ivoire Basin.Thirdly,by development first and expanding the surrounding areas,bp has found giant fields in the South Caspian Sea.In view of the practice of the major international oil companies in carrying out transnational deepwater and ultra-deepwater exploration,three enlightenments are summarized.Firstly,farming in advance,in the way of seizing the favorable exploration domains,and flexibly farming in and farming out.Secondly,following the strategy,constantly accumulating experience and technology to steadily improve strength.Thirdly,independent exploration,mastering key core technologies to achieve exploration efficiency. Chinese oil companies still need to seize all opportunities to actively obtain favorable exploration blocks, formeffective reserves of resources, and realize the leap from “going out” to “going up” through “one tr
