Abstract

"FLUXìMETRO PARA INDICAR FLUXO DE FLUIDO NUM DUTODE POçO". Um fluxímetro para uso em um poço de petróleo comuma região de perfuração central (3) na qual um tubo anular (8) éfixo coaxialmente com a região de perfuração central (3) por umanel (9), que também veda a folga entre a perfuração interna daregião de perfuração central (3) e o tubo (8) em sua extremidade ajusante, desse modo formando uma cavidade (10) aberta nadireção de fluxo de fluido através da região de perfuração central(3). A cavidade (10) leva o fluido para descanso, desse modoconvertendo toda a pressão dinâmica do fluido em pressãoestática. Isto tem o efeito de maximizar o diferencial de pressãoobtenível entre a região de perfuração central (3) e uma posição amontante do tubo (8), que permite que meios de cálculo eletrónicos(19) (figura 1) sejam capazes de fornecer uma medição de taxa defluxo mais precisa do que teria sido possível sem a cavidade (10).Na figura 3, outro fluxímetro é formado de tal modo que a região deperfuração central (3) tem uma seção transversal oval. Primeira esegunda cavidades (30) e (31) são formadas por segmentos detubo (32) e (33) e fechos (34) e (35). A perfuração da região deperfuração central (3) é aumentada na direção onde a presença derecessos (23) e (24) não predetermina estas dimensões deperfuração interna. Isto permite cavidades mais amplas (30) e (31),que fornecem uma pressão de estagnação maior na cavidade (10)
