摘要 |
The invention relates to system and method for desanding an oil well that includes a fluidizing device (TORE), connected to a downhole pump that connects to a production tubing such that a supply duct is connected to the discharge of the pump and a discharge duct is connected to the suction of the pump. Embodiments include a pressure balance transition device between the TORE and the pump and/or a flow splitting device in the production tubing after the discharge of the pump. Other embodiments relate to a system and method for desanding an oil well in which a fluidizing unit is connected to a pump such that the supply duct is connected to an opening in the pump body or pump rotor and a discharge duct is connected to the suction of the pump. If connected to the rotor, the supply duct is integral to the pump rotor. |
