井下泵送设备和方法
摘要：
一种设备，所述设备包括用于密封钻井的密封装置、用于从下钻井部泵送流体的第一泵、使用钻井气体提供动力的泵驱动器、用于为所述泵驱动器供应钻井气体的气体入口、以及用于从所述泵驱动器将钻井气体排出到上钻井部的气体出口。所述设备可以进一步包括用于将流体从所述上钻井部泵送到所述下钻井部中的第二泵、用于将钻井气体排放到所述上钻井部的排放装置、以及用于控制所述泵驱动器的开关。一种用于使钻井中的流体移动的方法，所述方法包括密封所述钻井、将钻井气体供应至泵驱动器以及使用所述泵驱动器驱动所述第一泵。所述方法可以进一步包括使用所述泵驱动器驱动第二泵以及将所述钻井气体排放到上钻井部。
摘要（英）：

An apparatus including a sealing device for sealing a wellbore, a first pump for pumping fluids from a lower wellbore section, a pump drive powered using wellbore gas, a gas inlet for supplying the pump drive with wellbore gas, and a gas outlet for exhausting wellbore gas to an upper wellbore section from the pump drive. The apparatus may further include a second pump for pumping fluids from the upper wellbore section into the lower wellbore section, a vent for venting wellbore gas to the upper wellbore section, and a switch for controlling the pump drive. A method for moving fluids in a wellbore including sealing the wellbore, supplying wellbore gas to a pump drive and driving a first pump with the pump drive. The method may further include driving a second pump with the pump drive and venting the wellbore gas to an upper wellbore section.
