Resumo: | In the Oil industry, artificial elevation methods become indispensable for wells with low productivity history. The implantation of these methods especially the pump ones arises new challenges related to the production of gas in contact with the pump. Therefore, gas separators are installed at the bottom of the well to ensure that the gas is directed to the annulus making the pump method viable to the well. However, it is necessary to release the confined gas in the annular, since it can cause an increase in the pressure of the coating so as to generate a back pressure at the pressure of the production line, and thus, the ejector, which is an equipment which has been studied with the function of using a high velocity main fluid to suck a secondary fluid, is connected to the wellhead to promote the releasement of the gas from the annulus. Therefore, the present analysis is part of a larger project which has been directed to the study of ejectors, and this research is focused on the dimensioning of parameters in the ejector (length and radius of the throat) seeking a greater efficiency for mature fields. The study was carried out in three stages: The search for literatures which produced a greater understanding of the studied instrument; The use of essential data (suction chamber geometry, nozzle geometry and diffuser sizing) from earlier studies of this project in order to find a higher efficiency ejector; Finally, the use of a CFD computational tool, in the commercial simulator ANSYS CFX, to design and simulate the fluid dynamics of the ejector. At this step several analysis were made based on different lengths and diameters of the throat in order to generate pressure graphs for a posterior analysis of the ejector type that fits as the most efficient. Therefore, among all tests performed, the dimensioning of the ejector in the throat area seeking the best configuration to raise efficiency has enabled different combinations of diameter and length, guaranteeing for the users a dimensioning without the need of an exclusive arrangement. |

Com a implantação desses métodos, em especial os bombeáveis, surgem novos desafios ligados a produção de gás em contato com a bomba do método aplicado. Por conta disto, separadores de gás são instalados no fundo do poço a garantir que o gás seja direcionado para o anular viabilizando a aplicação do método bombeável no poço. Entretanto, é necessário a liberação do gás confinado no anular para o meio externo, pois o gás confinado provoca um aumento de pressão do revestimento de modo a gerar uma contrapressão à pressão da linha de produção, e desta maneira, o ejetor, que é um equipamento a qual vem sendo estudado com a função de utilizar um fluido principal em alta velocidade para aspirar um fluido secundário, é vinculado à cabeça do poço para promover a saída do gás do anular. Portanto, a presente análise faz parte de um projeto mais amplo a qual tem se direcionado ao estudo dos ejetores, e esta pesquisa está focada no dimensionamento de parâmetros no ejetor (comprimento e raio da garganta) em busca de uma maior eficiência para campos maduros. O estudo foi realizado em três etapas: A busca de literaturas a qual produzisse um entendimento maior do instrumento estudado; A utilização de dados essenciais (geometria da câmara de sucção, geometria do bocal e dimensionamento do difusor) vindos de estudos anteriores deste projeto de modo a visualizar um ejetor de maior eficiência; E por último, o uso de uma ferramenta computacional CFD, no simulador comercial ANSYS CFX, para o desenho e simulações da fluidodinâmica do ejetor. Nesta etapa foram feitas diversas análises com base em distintos valores de comprimento e diâmetro da garganta (parte de um ejetor) de modo a gerar gráficos de pressão para uma análise posterior do tipo de ejetor que se enquadre como mais eficiente. Portanto, entre análises realizadas, o dimensionamento do ejetor na área da garganta em busca da melhor configuração a elevar a eficiência, viabilizou diferentes combinações de diâmetro e comprimento a qual para o usuário garante um dimensionamento sem a necessidade de um arranjo exclusivo.Universidade Federal do Rio Grande do NorteUFRNBrasilEngenharia de PetróleoEjetor.CFD.Dimensionamento.Garganta.Avaliação do desempenho de ejetores em poços de petróleo em campos madurosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccessporreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNTEXTTCC - 2016 2 - Marcela Ferraz.pdf.txtExtracted texttext/plain59946https://repositorio.ufrn.br/bitstream/123456789/39502/1/TCC%20-%202016%202%20-%20Marcela%20Ferraz.pdf.txtcdf00f550611a49425e310188a7cd3aaMD51ORIGINALTCC - 2016 2 - Marcela Ferraz.pdfTcc 2016 2 Marcela Ferraz Guimarãesapplication/pdf1581994https://repositorio.ufrn.br/bitstream/123456789/39502/2/TCC%20-%202016%202%20-%20Marcela%20Ferraz.pdf7afefa72f014d7d6d26f6e27208674c6MD52LICENSElicense.txttext/plain756https://repositorio.ufrn.br/bitstream/123456789/39502/3/license.txta80a9cda2756d355b388cc443c3d8a43MD53123456789/395022021-09-27 11:50:41.109oai:https://repositorio.ufrn.br:123456789/39502PGNlbnRlcj48c3Ryb25nPlVOSVZFUlNJREFERSBGRURFUkFMIERPIFJJTyBHUkFOREUgRE8gTk9SVEU8L3N0cm9uZz48L2NlbnRlcj4KPGNlbnRlcj48c3Ryb25nPkJJQkxJT1RFQ0EgRElHSVRBTCBERSBNT05PR1JBRklBUzwvc3Ryb25nPjwvY2VudGVyPgoKPGNlbnRlcj5UZXJtbyBkZSBBdXRvcml6YcOnw6NvIHBhcmEgZGlzcG9uaWJpbGl6YcOnw6NvIGRlIE1vbm9ncmFmaWFzIGRlIEdyYWR1YcOnw6NvIGUgRXNwZWNpYWxpemHDp8OjbyBuYSBCaWJsaW90ZWNhIERpZ2l0YWwgZGUgTW9ub2dyYWZpYXMgKEJETSk8L2NlbnRlcj4KCk5hIHF1YWxpZGFkZSBkZSB0aXR1bGFyIGRvcyBkaXJlaXRvcyBkZSBhdXRvciBkYSBtb25vZ3JhZmlhLCBhdXRvcml6byBhIFVuaXZlcnNpZGFkZSBGZWRlcmFsIGRvIFJpbyBHcmFuZGUgZG8gTm9ydGUgKFVGUk4pIGEgZGlzcG9uaWJpbGl6YXIgYXRyYXbDqXMgZGEgQmlibGlvdGVjYSBEaWdpdGFsIGRlIE1vbm9ncmFmaWFzIGRhIFVGUk4sIHNlbSByZXNzYXJjaW1lbnRvIGRvcyBkaXJlaXRvcyBhdXRvcmFpcywgZGUgYWNvcmRvIGNvbSBhIExlaSBuwrAgOTYxMC85OCwgbyB0ZXh0byBpbnRlZ3JhbCBkYSBvYnJhIHN1Ym1ldGlkYSBwYXJhIGZpbnMgZGUgbGVpdHVyYSwgaW1wcmVzc8OjbyBlL291IGRvd25sb2FkLCBhIHTDrXR1bG8gZGUgZGl2dWxnYcOnw6NvIGRhIHByb2R1w6fDo28gY2llbnTDrWZpY2EgYnJhc2lsZWlyYSwgYSBwYXJ0aXIgZGEgZGF0YSBkZXN0YSBzdWJtaXNzw6NvLiAKRepositório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2021-09-27T14:50:41Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false |
