21世纪以来,随着桑托斯盆地深水盐下获得一系列重大油气发现,巴西东部海域成为全球深水油气勘探与生产的热点区域。通过全面回顾巴西油气勘探开发历程,系统阐述了从陆上到海域、从浅水到深水—超深水直至盐下勘探的探索实践、战略转变、重大突破和关键理论技术。巴西国家石油公司(简称巴西国油)自1953年成立以后的15年间,在陆上古生界克拉通盆地和断陷盆地进行了勘探,并于断块和三角洲砂体圈闭获得了一些中小型油气发现。20世纪70年代,应用重力流沉积模式和高质量三维地震等勘探新技术,在坎波斯盆地浅水中发现Namorado和Enchova等油田,随后深水盐上勘探获得突破,成功发现marlim、roncador等大型油田。21世纪初,通过盐下含油气系统、碳酸盐岩成储成藏模式和核磁共振测井等理论技术攻关,推动桑托斯盆地下白垩统湖相碳酸盐岩陆续获得Tupi(Lula)、Buzios、mero等世界级超深水盐下大油田的系列重大发现。在复杂的深水作业环境下,油气开发工程面临巨大挑战,巴西国油通过启动深水研发计划(PrOCAP),开发并实施窄压力窗口控压钻井、加压钻井液帽钻井、多段智能完井、水下采油及浮式生产平台开发和流动保障等关键技术,显著提升了钻完井、油气田开发和输运的效率及安全性。此外,在浮式采储卸油系统建产规模受限的情况下,推进全球最大规模的CO_(2)捕集、驱油利用与埋存工程(CCUS-EOr),有效减少温室气体排放并提高了原油采收率。上述理论技术的发展和应用,也为全球深水油气勘探开发提供了宝贵经验。未来巴西油气勘探将继续聚焦深水盐下碳酸盐岩和盐上浊积岩,并在古生界天然气等勘探领域持续寻求新的发现,同时通过技术创新和战略合作,促进巴西石油天然气行业的可持续发展。

在阿根廷当代电影的语境下,制片公司潘佩罗小组(El Pampero Cine)因反对体制性公式化的筹资模式,以及决定不申请阿根廷全国电影和视听艺术委员会(INCAA)提供的补贴而闻名。与其他小众制作的阿根廷新电影相比,这种模式另辟蹊径:因为在新电影崛起和巩固的过程中,阿根廷全国电影和视听艺术委员会(INCAA)发挥了特殊作用(有人认为其补贴至关重要,而另一些人则认为那仅是一个传说)。潘佩罗小组(El Pampero)外在于全国艺术委员会的框架开展工作,制定了特定的模式和策略,他们的这种模式在电影创作的不同层面都有所反映:包括筹资模式、电影制作和拍摄方式以及为其项目量身打造的发行和放映程式。他们的影片也受到这种创作过程的影响,并处处渗透出这种特殊的电影制作模式的痕迹。不仅如此,在某些情况下潘佩罗小组关于电影筹资和媒介制度化的立场被明确纳入他们创作的故事当中。总而言之,本文分析了潘佩罗小组的整体宗旨和他们按照“独立电影是什么”或者说“独立电影”应该是什么这一理念所进行的电影创作。

A paleoglacier reconstruction during the Last Glacial maximum(LGm) is presented for a high mountain area of La Covacha massif in Sierra de Gredos(Iberian Central System) in central Spain. The moraines that, according with the previous literature, had formed during the global LGm, were mapped through photo interpretation of digital aerial photographs and 3D images and detailed field surveys. The topography of the paleoglaciers was estimated using a simple steady-state model that assumed a perfectly plastic ice rheology, reconstructing the theoretical ice profiles and obtaining the ice thickness of the glaciers during the LGm. The reconstruction of the glaciers was carried out using automated and semi-automated physically-based models, obtaining more realistic results with semi-automated models. According to our study, the paleoglaciers in the study area covered an area of 34.79 km^2 during the global LGm, with a maximum ice thickness of 366 meters in La Vega gorge, a total volume of 34.25 × 108 m^3 and a mean paleoELA of 1932 meters. most of the ice(~82%) was in paleoglaciers facing north, and the rest was in paleoglaciers with other orientations. This emphasizes the importance of orientation in relation to glacier dynamics and ice accumulation. The results obtained in the calculation of paleoELAs during the global LGm in Gredos are average compared to the Iberian mountains of the Northwest where the values were much lower, and with respect to those of the Southwest, much higher. This demonstrates the importance of the exposure of mediterranean mountains to the humidity sources coming from the NW during the global LGm, as is the case at present.
