Previous issue date: 2004-11-17 / Amongst the results of the AutPoc Project - Automation of Wells, established between UFRN and Petrobras with the support of the CNPq, FINEP, CTPETRO, FUNPEC, was developed a simulator for equipped wells of oil with the method of rise for continuous gas-lift. The gas-lift is a method of rise sufficiently used in production offshore (sea production), and its basic concept is to inject gas in the deep one of the producing well of oil transform it less dense in order to facilitate its displacement since the reservoir until the surface. Based in the use of tables and equations that condense the biggest number of information on characteristics of the reservoir, the well and the valves of gas injection, it is allowed, through successive interpolations, to simulate representative curves of the physical behavior of the existing characteristic variable. With a simulator that approaches a computer of real the physical conditions of an oil well is possible to analyze peculiar behaviors with very bigger speeds, since the constants of time of the system in question well are raised e, moreover, to optimize costs with assays in field. The simulator presents great versatility, with prominance the analysis of the influence of parameters, as the static pressure, relation gas-liquid, pressure in the head of the well, BSW (Relation Basic Sediments and Water) in curves of request in deep of the well and the attainment of the curve of performance of the well where it can be simulated rules of control and otimization. In moving the rules of control, the simulator allows the use in two ways of simulation: the application of the control saw software simulated enclosed in the proper simulator, as well as the use of external controllers. This implies that the simulator can be used as tool of validation of control algorithms. Through the potentialities above cited, of course one another powerful application for the simulator appears: the didactic use of the tool. It will be possible to use it in formation courses and recycling of engineers / Dentre os resultados do Projeto AutPoc – Automa??o de Po?os, estabelecido entre UFRN e Petrobras com o apoio do CNPq, FINEP, CTPETRO, FUNPEC, foi desenvolvido um simulador para po?os de petr?leo equipados com o m?todo de eleva??o por gas-lift cont?nuo. O gas-lift ? um m?todo de eleva??o bastante utilizado em produ??o offshore (produ??o marinha), e seu conceito fundamental ? injetar g?s no fundo do po?o produtor de petr?leo tornando-o menos denso de modo a facilitar seu deslocamento desde o reservat?rio at? a superf?cie. Baseado na utiliza??o de tabelas e equa??es que condensam o maior n?mero de informa??es sobre caracter?sticas do reservat?rio, do po?o e das v?lvulas de inje??o de g?s, ? permitido, atrav?s de sucessivas interpola??es, simular curvas representativas do comportamento f?sico das vari?veis caracter?sticas existentes. Com um simulador que aproxime um computador das condi??es f?sicas reais de um po?o de petr?leo ? poss?vel analisar comportamentos peculiares com velocidades muito maiores, visto que as constantes de tempo do sistema em quest?o s?o bem elevadas e, al?m disso, otimizar custos com ensaios em campo. O simulador apresenta grande versatilidade, destacadamente a an?lise da influ?ncia de par?metros, como a press?o est?tica, raz?o g?s-l?quido, press?o na cabe?a do po?o, BSW (Basic Sediments and Water) em curvas de solicita??o no fundo do po?o e a obten??o da curva de desempenho do po?o onde pode-se simular regras de controle e otimiza??o. No tocante as regras de controle, o simulador permite a utiliza??o em dois modos de simula??o: a aplica??o do controle via software simulado inclu?do no pr?prio simulador, bem como a utiliza??o de controladores externos. Isto implica que o simulador pode ser utilizado como ferramenta de valida??o de algoritmos de controle. Atrav?s das potencialidades acima citadas, naturalmente surge uma outra poderosa aplica??o para o simulador: a utiliza??o did?tica da ferramenta. Ser? poss?vel utiliz?-lo em cursos de forma??o e reciclagem de engenheiros
