Abstract
MÉTODOS PARA DIRECIONAR UMA BROCA DE PERFURAÇÃO PARA FORMAR UM FURO TENDO UMA INCLINAÇÃO E UM AZIMUTE EM UMA FORMAÇÃO SUBSUPERFÍCIE USANDO UM TRAJETO DE POÇO PLANEJADO E PELO MENOS PRIMEIRO E SEGUNDO LEVANTAMENTOS
Refere-se a invenção a um método para direcionar uma broca de perfuração para formar um furo tendo uma inclinação e um azimute em uma formação subsuperfície usando um trajeto de poço planejado e pelo menos primeiro e segundo levantamentos, compreendendo as etapas de:
a) determinar uma distância a partir do projeto de um poço, onde a distância do projeto é a diferença entre a posição da broca no segundo levantamento e o trajeto de poço planejado; e,
b) determinar um ângulo deslocado a partir do projeto do poço, em que o ângulo deslocado a partir do projeto é a diferença entre a inclinação e o azimute do trajeto de poço planejado;
c) em que pelo menos uma distância a partir do projeto e pelo menos um ângulo deslocado a partir do projeto são determinados em tempo real com base, pelo menos em parte, em uma porção do furo no primeiro levantamento, em uma posição em uma localização corrente projetada da broca, e em uma posição projetada da broca.
Description
TRAJETO DE POÇO PLANEJADO E PELO MENOS PRIMEIRO E 5 SEGUNDO LEVANTAMENTOS”
1. Campo da invenção A presente invenção se refere em geral a métodos e sistemas para perfuração em várias formações subsuperfície tais como formações contendo hidrocarboneto.
2. Descrição da Técnica Relacionada Hidrocarbonetos obtidos de formações subterrâneas são geralmente usados como recursos de energia, como cargas de alimentação, e como produtos de consumo. Preocupações sobre o esgotamento de fontes de hidrocarbonetos disponíveis e preocupações sobre o declínio da qualidade global de hidrocarbonetos produzidos levaram ao desenvolvimento de processos para recuperação, processamento e/ou uso mais eficiente de fontes de hidrocarbonetos disponíveis. Em operações de perfuração, pessoal de perfuração é comumente designado de várias funções de controle e monitoramento. Por exemplo, pessoal de perfuração pode controlar ou monitorar posições do aparelho de perfuração (tal como um acionador rotativo ou acionador de transporte), coletar amostras de fluido de perfuração, e monitorar agitadores. Como outro exemplo, pessoal de perfuração ajusta o sistema de perfuração (“manobra” uma coluna de perfuração) em uma base caso a caso para ajustar ou corrigir a taxa de perfuração, trajetória, ou estabilidade. Um perfurador pode controlar parâmetros de perfuração usando manches, comutadores
