No. of bitstreams: 1 DiegoAMF_DISSERT.pdf: 1096063 bytes, checksum: 5fc2d5a69c06dbd0861b8cfebf12e262 (MD5) Previous issue date: 2011-10-10 / Petr?leo Brasileiro SA - PETROBRAS / This document proposes to describe a pilot plant for oil wells equipped with plunger lift. In addition to a small size (21,5 meters) and be on the surface, the plant s well has part of its structure in transparent acrylic, allowing easy visualization of phenomena inherent to the method. The rock formation where the well draws its pilot plant fluids (water and air) is simulated by a machine room where they are located the compressor and water pump for the production of air and water. To keep the flow of air and water with known and controlled values the lines that connect the machine room to the wellhole are equipped with flow sensors and valves. It s developed a supervisory system that allows the user a real-time monitoring of pressures and flow rates involved. From the supervisor is still allowed the user can choose how they will be controlled cycles of the process, whether by time, pressure or manually, and set the values of air flow to the water used in cycles. These values can be defined from a set point or from the percentage of valve opening. Results from tests performed on the plant using the most common forms of control by time and pressure in the coating are showed. Finally, they are confronted with results generated by a simulator configured with the the pilot plant s feature / Este trabalho se prop?e a descrever uma Planta Piloto para po?os de petr?leo equipados com eleva??o artificial do tipo plunger lift. Al?m de um tamanho reduzido (21,5 metros) e estar sobre a superf?cie, o po?o da planta possui parte de sua estrutura em acr?lico transparente, permitindo a f?cil visualiza??o de fen?menos inerentes ao m?todo. A forma??o rochosa donde o po?o da Planta Piloto extrai seus fluidos (?gua e ar) ? simulada por uma casa de m?quinas onde est?o localizados o compressor e a bomba centr?fuga respons?veis pela produ??o de ar e ?gua. Para manter as vaz?es desses fluidos com valores conhecidos e controlados as linhas que conectam a casa de m?quina ao fundo do po?o s?o equipadas com sensores de vaz?o e v?lvulas. ? desenvolvido um sistema supervis?rio que permite ao usu?rio uma monitora??o em tempo real das press?es e vaz?es envolvidas no processo. A partir do supervis?rio ? poss?vel ainda o usu?rio escolher a forma como ser?o controlados os ciclos do processo, se por tempo, por press?o ou manualmente, e definir os valores de vaz?o de ar a ?gua utilizados durantes os ciclos. Esses valores podem ser definidos a partir de um set point ou a partir da porcentagem de abertura das v?lvulas. S?o apresentados resultados de testes realizados na planta utilizando as formas de controle mais usuais: por tempo e por press?o no revestimento. Por fim, estes ser?o confrontados com resultdos gerados por um simulador configurados com as caracter?sticas da Planta Piloto
