Abstract
resumo válvula verificadora de fundo de poço e método para operar uma válvula verificadora de fundo de poço uma válvula verificadora de fundo do poço (100) inclui um arranjo de carcaça (106) e um arranjo de mandril (172, 174) que definem entre eles uma câmara de fluido de operação (176), uma câmara de fluido de pressionamento (184) e uma câmara de fluido de alimentação (180). um arranjo de válvula (126) disposto dentro do arranjo de carcaça (106) é operável entre as posições aberta e fechada. um arranjo de êmbolo (146) está operacionalmente associado com o arranjo de válvula (126), de tal forma que a pressão no espaço anular entra na câmara de fluido de alimentação (180) pressurizando o fluido de operação na câmara de fluido de operação (176) o qual atua sobre o arranjo de êmbolo (146) para deslocar o arranjo de válvula (126) a partir da posição fechada para a posição aberta, e de forma que o percurso predeterminado do arranjo do êmbolo (146) abre uma passagem de derivação (162) para o fluido de operação pressurizado para carregar o fluido de pressionamento na câmara de fluido de pressionamento (184), permitindo assim, o fechamento do arranjo de válvula (126) mediante a redução da pressão no espaço anular por um valor predeterminado. 1/1abstract downhole check valve and method of operating a downhole check valve a downhole check valve (100) includes a housing arrangement (106) and a mandrel arrangement (172, 174) that define among them an operating fluid chamber (176), a pressing fluid chamber (184) and a supply fluid chamber (180). a valve arrangement (126) disposed within the housing arrangement (106) is operable between the open and closed positions. a piston arrangement (146) is operatively associated with the valve arrangement (126) such that pressure in the annular space enters the supply fluid chamber (180) pressurizing the operating fluid in the operating fluid chamber (180). 176) which acts on the plunger arrangement (146) to move the valve arrangement (126) from the closed to the open position, and such that the predetermined path of the plunger arrangement (146) opens a passage of bypass (162) for pressurized operating fluid to charge the pressing fluid into the pressing fluid chamber (184), thereby allowing closure of the valve arrangement (126) by reducing the pressure in the annular space by a predetermined amount . 1/1
