DOWNHOLE DESANDER


SEPARATES ABRASIVE SOLIDS IN PRODUCTION FLUIDS

BEFORE THEY ENTER A DOWNHOLE PUMP

EXTENDS LIFE OF ALL TYPES OF DOWNHOLE PUMPS

SIMPLE TO INSTALL AND INEXPENSIVE


FEATURES:

  • Run on the tubing below any type of downhole pump
  • Centrifugal action separates all size of solid particles
  • Collects solids in extended length of mud anchor or in the rathole
  • Does not plug or restrict production
  • Available for wide range of flow rates
  • No moving parts
  • All steel construction
  • Long life
  • May serve as “Poor Boy” gas anchor

Figure 1 : Illustrates the flow path of produced fluids thru the desander sub. Fluid enters the tubing thru the inlet slots. The fluid must flow down thru a spiral to enter the orifice tube and flow upward to the pump. Centrifugal action created by the fluids flow thru the spiral push solids away from the fortex flow of the orifice tube.  Solids settle into the mud anchor or rathole. The clean fluids flows upward thru the orifice tube to the pump.
