The Principle and Calculation of Hydraulic Driven Downhole Twin-Screw Pump
Structure composition and working principle of hydraulic driven downhole twin-screw pump are firstly introduced, and the calculation method of work and structure parameters when downhole twin-screw pump and turbine motor operate is given, and dynamic measuring process when ground power pump, turbine motor and downhole twin-screw pump coordinate is also given. The given calculation process which is derived after sufficiently considering working principle and structure features of the pump, is instructive to the design of this kind of downhole twin-screw pump, and also provides technical support for series design of hydraulic driven downhole twin-screw pump in the future.
