Abstract

"DESVIADOR ROTATIVO". Fornece-se um desviador (108)rotativo para isolar fluido em um poço (30) a partir de outro fluidoacima do poço (30). O desviador (108) rotativo inclui uma carcaça(162) de compartimento que apresenta um orifício (168)funcionando através do mesmo. Um conjunto (178) de fusorecuperável que inclui um fuso (178) e um conjunto (184) demancal é disposto no orifício (168). O conjunto (184) de mancalapoia o fuso (178) para rotação. O fuso (178) é adaptado parareceber e vedar em torno de um membro tubular, e rotação domembro tubular gira o fuso (178) no interior do orifício (168). Ummembro (176) de trava é disposto na carcaça (162) decompartimento para segurar o conjunto (178) de fuso recuperáveljunto a carcaça (162) de compartimento.
