Design and analysis of a conveyor lift pump
The Conveyer Lift Pump uses viscous drag to lift liquids. The pumputilizes a flexible continuous rope or conveyer, affixed about a sheave at the top and bottom of the well moving upward inside the production tubing, viscously dragging or lifting the fluid from the well. Presented here are mathematical derivations for the flow rate, the quantity of fluid to be lifted, the required drag force at the rope surface, the power input required by the system, and efficiency of this lift system. Concentric and eccentric solutions are presented.
