Abstract

resumo “sistema para ativar múltiplas ferramentas de poço de fundo do poço, método para ativar múltiplos dispositivos de carga no fundo de poço e sistema para ativar múltiplos dispositivos de carga bidirecionais no fundo de poço” um sistema para seletivamente ativar múltiplos dispositivos de carga, tais como ferramentas de poços, as quais são seletivamente acionadas através da aplicação de uma voltagem predeterminada através de um par predeterminado de condutores. pelo menos um dispositivo de bloqueio é associado com cada dispositivo de carga. o dispositivo de bloqueio impede o fluxo da corrente através do respectivo dispositivo de carga até que a voltagem através do par de condutores excede um mínimo predeterminado. um método é provido para a seleção das ferramentas de poço para o acionamento por meio de aplicação de uma voltagem mínima através de um conjunto de condutores e um dispositivo de bloqueio. trajetos parasitas são impedidos a partir do escoamento da corrente para os dispositivos de bloqueio. um sistema é provido para a aplicação de corrente aos dispositivos de carga bidirecionais, tais como, bombas e motores de fundo de poço. 1abstract system for activating multiple downhole well tools, method for activating multiple downhole loading devices, and system for activating multiple downhole bidirectional loading devices a system for selectively activating multiple downhole loading devices, such such as well tools, which are selectively driven by applying a predetermined voltage across a predetermined pair of conductors. at least one locking device is associated with each load device. The blocking device prevents the flow of current through the respective charging device until the voltage across the pair of conductors exceeds a predetermined minimum. A method is provided for selecting downhole tools for actuation by applying a minimum voltage across a set of conductors and a locking device. Parasitic paths are prevented from flowing current to the blocking devices. A system is provided for applying current to bidirectional load devices such as downhole pumps and motors. 1
