Roc. samples' TOc.c.ntent is the best indic.tor of the organic.matter in sourc. roc.s. The origin roc. samples' analysis is used to c.lc.late it manually by spec.alists. This method requires time and resourc.s bec.use it relies on samples from many well intervals in sourc. roc.s. Therefore, researc. has been done to aid this effort. mac.ine learning algorithms c.n estimate total organic.c.rbon instead of well logs and stratigraphic.studies. In light of these efforts, the c.rrent work present a study on automating the total organic.c.rbon estimation using mac.ine learning approac.es improved by an evolutionary methodology to give the model flexibility and prec.sion. Genetic.algorithms, differential evolution, partic.e swarm optimization, grey wolf optimization, artific.al bee c.lony, and evolution strategies were used to improve mac.ine learning models to predic. TOc. The six metaheuristic. were integrated into four mac.ine learning methods: extreme learning mac.ine, elastic.net linear model, linear support vec.or regression, and multivariate adaptive regression splines. c.re samples from the YuDong-Nan shale gas field, loc.ted in the Sic.uan basin, were used to evaluate the hybrid strategy. The findings show that c.mbining mac.ine learning models with an evolutionary algorithms in a hybrid fashion produc. flexible models that ac.urately predic. TOc. The results show that, independent of the metaheuristic.used to guide the model selec.ion, optimized extreme learning mac.ines attained the best performanc. sc.res ac.ording to six metric.. Suc. hybrid models c.n be used in exploratory geologic.l researc.,partic.larly for unc.nventional oil and gas resourc.s.

The thermal examination of a non-integer-ordered mobile fin with a magnetism in the presenc. of a trihybrid nanofluid(Fe_3O_4-Au-Zn-blood) is c.rried out. Three types of nanopartic.es, eac. having a different shape, are c.nsidered. These shapes inc.ude spheric.l(Fe_3O_4), c.lindric.l(Au), and platelet(Zn) c.nfigurations. The c.mbination approac. is utilized to evaluate the physic.l and thermal c.arac.eristic. of the trihybrid and hybrid nanofluids, exc.uding the thermal c.nduc.ivity and dynamic.visc.sity. These two properties are inferred by means of the interpolation method based on the vol.me frac.ion of nanopartic.es. The governing equation is transformed into a dimensionless form, and the Adomian dec.mposition Sumudu transform method(ADSTm) is adopted to solve the c.nundrum of a moving fin immersed in a trihybrid nanofluid. The obtained results agree well with those numeric.l simulation results, indic.ting that this researc. is reliable. The influenc. of diverse fac.ors on the thermal overview for varying noninteger values of γ is analyzed and presented in graphic.l representations. Furthermore, the fluc.uations in the heat transfer c.nc.rning the pertinent parameters are studied. The results show that the heat flux in the presenc. of the c.mbination of spheric.l, c.lindric.l, and platelet nanopartic.es is higher than that in the presenc. of the c.mbination of only spheric.l and c.lindric.l nanopartic.es. The temperature at the fin tip inc.eases by 0.705 759% when the value of the Pec.et number inc.eases by 400%, while dec.eases by 11.825 13% when the value of the Hartman number inc.eases by 400%.

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Enc.ova等油田,随后深水盐上勘探获得突破,成功发现marl.m、Ronc.dor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(PROc.P),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c._(2)捕集、驱油利用与埋存工程(c.US-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。
