REVERSE FLOW GAS SEPARATOR FOR PROGRESSING CAVITY SUBMERGIBLE PUMPING SYSTEMS |
摘要 |
A system for separating gas from a wellbore fluid as it is produced to the surface. The system includes a progressing cavity pump, a submergible electric motor and a fluid intake. The submergible electric motor is connected to the progressing cavity pump to drive the pump and draw wellbore fluid through the fluid intake. The fluid intake includes a hollow interior defined by a thick-walled section. Additionally, the fluid intake includes a plurality of fluid passageways extending through the thick-walled section. The passageways are oriented to create a reversal in fluid flow, and thus a release of gas, as the fluid is draw into the fluid intake.
