Abstract

"TELA PARA POçO, E, PROCESSO PARA MONTAR A MESMA". Uma tela para poço que tem um trajeto alternativo de escoamento interno para distribuir lama de cascalho para diferentes níveis dentro de uma coroa circular de um poço e um processo para montar a mesma. A tela é constituída de uma tubulação externa 18 que é posicionada de maneira concêntrica sobre uma tubulação base 17, de modo que uma coroa circular é formada entre elas. Ambas as tubulações são perfuradas ao longo de seus respectivos comprimentos, porém somente parcialmente ao redor de suas respectivas circunferências. As respectivas seções perfuradas se alinham radialmente uma como a outra quando as tubulações são montadas. Uma pluralidade de nervuras longitudinais 22 isolam a coroa circular 19 adjacente as seções perfuradas (isto é, o lado de produção da tela) da coroa circular adjacente às seções não perfuradas (isto é, o lado do trajeto alternativo de escoamento da tela). Pelo menos uma saída 20 é fornecida através da seção não perfurada da tubulação externa, para fornecer uma saída a partir do trajeto alternativo de escoamento interno.
