Abstract

MéTODO DE CONTROLAR A TRAJETóRIA DE UMA COLUNA DE PERFURAçãO. A modelagem do comportamento da dirigibilidade pode incluir equações da velocidade de desenvolvimento e/ou da velocidade de rotação para modelar o comportamento da composição de fundo do poço. As equações de desenvolvimento e/ou de rotação podem ser calibradas mediante ajustar parâmetros de modelagem desses mencionados para minimizar qualquer variância entre a resposta vigente no momento 118 e resposta estimada produzida para um intervalo do poço. A posição e orientação estimadas 104 de uma composição de fundo do poço ao longo de um subseqUente intervalo pode ser gerada introduzir dados das subsequentes ajustagens de ferramenta na modelagem do comportamento da dirigibilidade calibrada. A posição e orientação estimadas 104 podem ser comparadas a um plano de perfuração de poço 106 com um controlador 108 que determina uma ação corretiva 110. A ação corretiva 110 pode ser convertida de uma velocidade de desenvolvimento e/ou de rotação a um conjunto de ajustagens recomendadas das ferramentas 114 mediante utilizar uma aplicação inversa 112 da modelagem do comportamento da dirigibilidade. à medida que dados adicionais 118 se tornam disponíveis, a modelagem do comportamento da dirigibilidade pode ser adiCionalmente Calibrada 102 através da interação.
