国际大油公司深水油气勘探实践及启示 ——以圭亚那斯塔布鲁克区块为例 摘　要：近年来，国际大油公司持续在深水领域取得勘探突破。其中埃克森美孚公司领导的勘探联合体在圭亚 那的斯塔布鲁克区块获得 31 个深水油气田发现，使圭亚那成为南美地区石油行业的重要国家之一，同时也带动了 周边海域的勘探热潮。圭亚那盆地横跨圭亚那和苏里南海域，埃克森美孚公司在圭亚那盆地的油气勘探主要经历了 3 个阶段，分别是 1957—1982 年超前布局圭亚那盆地苏里南海域；1999—2015 年再进圭亚那盆地并长期坚守圭亚 那海域；2015 年至今地质认识和地震技术助推获得一系列勘探发现。国际大油公司，尤其是埃克森美孚公司领导 的勘探联合体在圭亚那的勘探实践表明，开展区域地质综合研究并结合新资料坚定勘探信心，通过引进合作伙伴共 担风险、共享收益，是风险勘探的典型做法，可为中国油公司实现从“走出去”迈向“走上去”开展海外油气勘探 业务提供借鉴和参考。 关键词：圭亚那；埃克森美孚公司；深水油气勘探；全波反演；斯塔布鲁克区块 Abstract: In recent years, exploration breakthroughs have continuously been obtained in deepwater fields by major international oil companies. Among them, the joint venture company led by ExxonMobil has discovered 31 deepwater oil and gas fields in Stabroek block in Guyana, making it a rising star in the petroleum industry in South America and driving the exploration boom in the peripheral offshore areas. Guyana Basin spans Guyana and Suriname offshore areas. ExxonMobil’s petroleum exploration in Guyana Basin mainly experienced three stages, namely, the advanced layout in Suriname offshore area during the 1957-1982, re-exploration in Guyana Basin and long-term research in Guyana offshore area during the 1999-2015, and a series of discoveries by applying new geological understanding and seismic technologies since 2015. The exploration practice of major international oil companies in Guyana, especially the joint venture company led by ExxonMobil, shows that it is a feasible and typical way to implement risk exploration by conducting comprehensive regional geological study and applying new data to strengthen exploration confidence and introducing partners to share risks and benefits, which provides reference for Chinese oil companies in promoting overseas petroleum exploration business from “going global” to “going better”. : Key words Guyana, ExxonMobil, deepwater exploration, full waveform inversion, Stabroek block
