摘要： 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.
摘要翻译： 一种装置，包括用于密封井眼的密封装置，用于从下部井眼部分泵送流体的第一泵，使用井筒气体驱动的泵驱动器，用于向井筒气体供应泵驱动器的气体入口和用于排出井眼的气体出口 气体到泵驱动器的上部井筒部分。 该装置还可以包括用于将流体从上井筒部分泵送到下井筒部分中的第二泵，用于将井眼气体排放到上井筒部分的排气口以及用于控制泵驱动装置的开关。 一种用于在井筒中移动流体的方法，包括密封井筒，将井筒气体供应到泵驱动器并且用泵驱动器驱动第一泵。 该方法还可以包括用泵驱动器驱动第二泵并将井筒气体排放到上井筒部分。
