STATIC GAS SEPARATOR FOR DOWNHOLE ELECTRIC SUBMERSIBLE PUMP

摘要

A static gas separator interposed between an electric submersible pump and a downhole motor to separate entrained gas from production fluid in a subterranean well. The gas separator includes an elongate cylindrical mandrel concentrically surrounded an outer static filter sleeve. A base member is attached at a lower end of the gas separator and includes a flange for connection with a mating flange on the pump. The upper end of the gas separator includes a head member attached thereto and includes a flange for connection with a mating flange on the motor. The gas separator includes a plurality of radially aligned, axial flow intakes in fluid communication with a hollow interior of the head member and a separating annulus formed between the outer static filter sleeve and the mandrel. The gas separator may also include radially protruding helical fins or vanes that impart a centrifugal force or vortex to the production well fluid flowing through the annulus.
