A prediction model for a new deep-rod pumping system
The side-flow pump is presented for increasing the setting depth of sucker rod pumping system, which adopts a special structure of side-flow valve, ladder-type solid plunger and breathing hole. By transferring the load of liquid column to the tubing on the upstroke, the new pump achieves a smaller p...
