Abstract

resumo patente de invenção: "sistema de energia para furo de poço". a presente invenção refere-se a um sistema de energia de furo de poço (1) compreendendo uma coluna tubular (2) compreendendo um fluído pressurizado (3), uma turbina (4), para converter energia do fluído pressurizado em rotação de um eixo (5) uma ferramenta (6, 6a) movida pela turbina, sendo que um conjunto de furo de poço de fluxo constante (7) é arranjado entre a coluna tubular e a turbina, para prover um fluxo substancialmente constante de fluído pressurizado à turbina, sendo que o conjunto de furo de poço de fluxo constante tem um eixo geométrico de montagem (9) e compreende um corpo (15) compreendendo um furo principal (16) tendo uma entrada de furo (17) e pelo menos uma saída de furo (18), um pistão oco (19) tendo uma entrada de pistão (32) e uma saída de pistão (33), o citado pistão oco sendo arranjado no furo principal e uma mola (34) sendo arranjada no furo principal , a citada mola sendo comprimida com o movimento do pistão em uma primeira direção (35), e sendo que a entrada de furo se comunica fluidicamente com a entrada de pistão, e a entrada de pistão é menor que a entrada de furo, de modo a forçar o pistão a se mover na primeira direção. a presente invenção também se relaciona a um conjunto de furo de poço de fluxo constante e a um método para prover um fluxo de fluído substancialmente constante a uma turbina do sistema de energia de furo de poço.patent summary: "wellbore power system". The present invention relates to a borehole power system (1) comprising a tubular column (2) comprising a pressurized fluid (3), a turbine (4) for converting energy from pressurized fluid to rotation of an axis. (5) a turbine-driven tool (6, 6a), with a constant flow wellbore assembly (7) arranged between the tubular column and the turbine to provide a substantially constant flow of pressurized fluid to the turbine, wherein the constant flow wellbore assembly has a mounting geometric axis (9) and comprises a body (15) comprising a main bore (16) having a bore inlet (17) and at least one bore outlet ( 18) a hollow piston (19) having a piston inlet (32) and a piston outlet (33), said hollow piston being arranged in the main bore and a spring (34) being arranged in the main bore, said spring being compressed with piston movement in a first direction (35), and wherein the bore inlet communicates fluidly with the piston inlet, and the piston inlet is smaller than the bore inlet in order to force the piston to move in the first direction. The present invention also relates to a constant flow wellbore assembly and a method of providing a substantially constant fluid flow to a wellbore power system turbine.
