Previous issue date: 2003-07-16 / The continuous gas lift method is the main artificial lifting method used in the oil industry for submarine wells, due to its robustness and the large range of flow rate that the
well might operate. Nowadays, there is a huge amount of wells producing under this mechanism. This method of elevation has a slow dynamics due to the transients and a
correlation between the injected gas rate and the of produced oil rate. Electronics controllers have been used to adjust many parameters of the oil wells and also to improve the efficiency of the gas lift injection system. This paper presents a intelligent control system applied to continuous gas injection in wells, based in production s rules, that has the target of keeping the wells producing during the maximum period of time, in its best operational condition, and doing automatically all necessary adjustments when occurs some disturbance in the system. The author also describes the application of the intelligent control system as a tool to
control the flow pressure in the botton of the well (Pwf). In this case, the control system actuates in the surface control valve / O m?todo de eleva??o por g?s lift cont?nuo ? o principal m?todo de eleva??o artificial utilizado, principalmente, para produ??o em po?os submarinos devido a sua robustez e a larga faixa de vaz?o que o po?o pode produzir. H? um grande percentual de po?os produzindo sob este mecanismo no Brasil. Este tipo de m?todo de eleva??o apresenta algumas caracter?sticas pr?prias, sendo uma delas sua din?mica lenta devido aos transientes e outra ? a exist?ncia de uma correla??o entre a vaz?o de g?s injetado e a vaz?o de ?leo produzido. Controladores eletr?nicos t?m sido utilizados para realizar ajustes em alguns par?metros do po?o e melhorar
a efici?ncia de inje??o de g?s lift. Este trabalho apresenta um sistema inteligente de controle autom?tico da inje??o de
g?s, baseando-se em regras de produ??o, que busca manter os po?os equipados para g?s lift cont?nuo produzindo o maior tempo poss?vel, nas condi??es ?timas de opera??o e que faz os ajustes autom?ticos necess?rios quando ocorre alguma perturba??o no sistema. Mostra-se que ? poss?vel, utilizando o sistema inteligente apresentado, exercer o controle da press?o de fluxo no fundo do po?o (Pwf) atrav?s da manipula??o da abertura da v?lvula de controle de
