Abstract

SISTEMA DE RELÉ TEMPORIZADOR EM REDE LINEAR DE ÍNDICE REDUZIDO DE POÇO E MÉTODO. A presente invenção se refere a um sistema de temporização de rede para uma plataforma de perfuração, incluindo uma linha de perfuração que se estende abaixo da superfície para baixo a partir de uma cabeça de poço na superfície. O sistema inclui um nó localizado na extremidade inferior da linha de perfuração e inclui um sensor adaptado para fornecer um conjunto de dados de sinal de saída que corresponde às condições de perfuração do fundo do poço. Múltiplos nós estão localizados no fundo do poço entre a coluna de perfuração (BHA) e a cabeça de poço, e estão associados com a linha de perfuração. Os nós são adaptados para receber e transmitir os sinais. O sistema de controle de temporização é adaptado para controlar todos os tempos dentro de um período de tempo, de acordo com as constantes pré-configuradas conhecidas de todos os nós. Um método de temporização da rede do repetidor linear de baixo índice do fundo do poço usa o sistema.TIMER RELAY SYSTEM ON REDUCED WELL RATE LINEAR NETWORK AND METHOD. The present invention relates to a network timing system for a drilling rig including a drill line extending below the surface downwards from a surface wellhead. The system includes a node located at the lower end of the drill line and includes a sensor adapted to provide an output signal dataset that corresponds to downhole drilling conditions. Multiple nodes are located downhole between the drillstring (BHA) and the wellhead, and are associated with the drillline. Nodes are adapted to receive and transmit signals. The timing control system is adapted to control all times within a period of time, according to pre-configured constants known to all nodes. A low-rate downhole linear repeater network timing method uses the system.
