Abstract
SUB DE CIRCULAÇÃO OPERADO POR TELEMETRIA. A presente invenção refere-se a um método de perfuração de um furo de poço que inclui perfurar o furo de poço por injetar fluido de perfuração através da coluna de perfuração que se estende dentro do furo de poço a partir de superfície e girar a ponta de broca da coluna de perfuração. A coluna de perfuração adicionalmente inclui um sub de circulação tendo uma porta fechada durante a per furação. O fluido de perfuração sai da ponta de broca e transporta cascalhos a partir da ponta de broca. O fluido de perfuração e cascalhos (retornos) fluem para a superfície por meio de um anel formado entre uma superfície externa da coluna tubular e uma superfície interna do furo de poço. O método adicionalmente inclui após a perfuração pelo menos uma porção do furo de poço: interromper perfuração; enviar um sinal de instrução sem fio a partir da superfície para a porção de fundo do poço da coluna de perfuração por articular a coluna de perfuração, sinal acústico, ou pulso de lama, desse modo abrindo a porta; e injetar fluido de perfuração através da coluna de perfuração e dentro do anel por meio da porta aberta.
