Resumo: | The primary cementing is one of the most important stages of the drilling process, because it is which will give to the oilwell the mechanical stability and protect the coating tube. The Portland Cement is the most binder used as cement slurry to the cementing operation of oilwells. Due the great concern about the environment, because the process of getting the Portland Cement releases greenhouse gases, there are the necessity to develop studies of slurries with others precursors. Calcium sulfate hemihydrate-α is a material with great environment potential. Its process of getting the hemihydrate-α it involves low cost when it is compared to the Portland Cement. This turns the hemihydrate-α into a substitute of the Portland Cement. The present work aims to study the behavior of the systems with calcium sulfate hemihydrate-α as binder basis to the slurries of well’s cementing. The hemihydrate-α was characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Absorption Spectroscopy in the Infrared Region (IR), X-Ray Fluorescence (XRF), Thermal Characterization Techniques (TG/DTG) and Grain Size. Different water/plaster factors (FWP) were developed in this work (0,5, 0,6, 0,7 and 0,8) and the slurries were submitted to different kinds of cure (wet, fully wet and air) and temperature (27, 38 e 60°C). The technology property, applied to the oil industry, evaluated in these slurries was the compressive strength, and following, the slurry with the best FWP chosen (FWP 0,5) was characterized by X-Ray Diffraction, Scanning Electron Microscopy and Thermal Characterization Techniques (TG/DTG). According to the results the best system of slurries based on calcium sulfate hemihydrate-α was the 0.5 FWG to the 27°C and 38°C temperatures, because their values of compressive strength were above of the established by the NBR 9831, 2006 standard. |

O aglomerado mais utilizado como material básico no processo de cimentação de poços de petróleo é o Cimento Portland. Devido à grande preocupação com o meio ambiente, já que o processo de obtenção di Cimento Portland libera gases de efeito estufa, há a necessidade de desenvolver estudos de pastas cimentícias com outros tipos de precursores. O sulfato de cálcio hemidratado-α é um material que apresenta grande potencial. Seu processo produtivo envolve baixo custo quando comparado ai cimento Portland. Isso o torna um provável substituto ao cimento. O presente trabalho teve como objetivo estudar o comportamento de sistemas de pastas à base de sulfato de cálcio hemidratado-α como aglomerante básico para pastas de cimentação de poços. O hemidrato-α foi caracterizado por meio de Difração de Raios-X (DRX), Microscopia Eletrônica de Varredura (MEV), Espectroscopia de Absorção na Região do Infravermelho (FT-IR), Fluorescência de Raios-X, Análise Termogravimétrica e Granulometria. Diferentes fatores de água/gesso (FAG) foram desenvolvidos neste estudo (0,5, 0,6, 0,7 e 0,8) e as pastas foram submetidas a diferentes tipos de cura (úmida, totalmente úmida e aérea) e temperaturas (27, 38 e 60°C). A propriedade tecnológica, aplicada à indústria do petróleo, avaliada nessas pastas foi a Resistência à Compressão, e em seguida a pasta com melhor FAG escolhida (FAG 0,5) foi caracterizada por Difração de Raios-X, Microscopia Eletrônica de Varredura e Análise Termogravimétrica. De acordo com os resultados obtidos o melhor sistema à base de sulfato de cálcio hemidratado-α foi o de FAG 0,5 para temperaturas de 27°C e 38°C, pois seus valores de resistência à compressão estavam todas acima da estabelecida pela norma NBR 9831, 2006.Universidade Federal do Rio Grande do NorteUFRNBrasilQuímica do PetróleoAttribution 3.0https://creativecommons.org/licenses/by/3.0/info:eu-repo/semantics/openAccessPoços de petróleo.Oilwells Cement.Cimentação primária.Sulfato de cálcio hemidratado-α.Primary cementing.Calcium sulfate hemihydrate-α.Pastas à base de sulfato de cálcio para aplicação em cimentação de poços de petróleoCalcium Sulfate Slurries to be Applicated on Cementing Operation of Oilwellsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisporreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNTEXTPastasBaseSulfatoCalcio_Silvestre_2015.pdf.txtExtracted texttext/plain102060https://repositorio.ufrn.br/bitstream/123456789/38308/1/PastasBaseSulfatoCalcio_Silvestre_2015.pdf.txt202bde5a27d531649d96bec7d196446eMD51ORIGINALPastasBaseSulfatoCalcio_Silvestre_2015.pdfapplication/pdf2112347https://repositorio.ufrn.br/bitstream/123456789/38308/2/PastasBaseSulfatoCalcio_Silvestre_2015.pdfb548776895c2333e9a22b010d0024e5cMD52CC-LICENSElicense_urlapplication/octet-stream43https://repositorio.ufrn.br/bitstream/123456789/38308/3/license_url321f3992dd3875151d8801b773ab32edMD53license_textapplication/octet-stream21080https://repositorio.ufrn.br/bitstream/123456789/38308/4/license_text61bae8834f24e8106e87f884f26f63a9MD54license_rdfapplication/octet-stream19874https://repositorio.ufrn.br/bitstream/123456789/38308/5/license_rdf38cb62ef53e6f513db2fb7e337df6485MD55LICENSElicense.txttext/plain756https://repositorio.ufrn.br/bitstream/123456789/38308/6/license.txta80a9cda2756d355b388cc443c3d8a43MD56123456789/383082023-05-19 10:47:20.972oai:https://repositorio.ufrn.br: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ório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2023-05-19T13:47:20Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false |
