APPARATUS, SYSTEM AND METHOD FOR SEALING SUBMERSIBLE PUMP ASSEMBLIES |
摘要 |
An apparatus, system and method for sealing an electrical submersible pump assembly are described. An electric submersible pump (ESP) system for pumping solid-laden fluid comprises a thrust chamber of an ESP seal section, the thrust chamber sealed from well fluid on a downstream side by a stationary sand barrier and on an upstream side by a mechanical seal, the thrust chamber further comprising, a rotatable shaft extending axially through the thrust chamber, a head tubularly encasing the thrust chamber and threadedly coupled to a centrifugal pump intake, and a diamond-coated hydrodynamic bearing set inside the thrust chamber, wherein well fluid enters and exits the chamber through cross-drilled apertures in the head of the chamber, and wherein the well fluid forms a hydrodynamic film between the bearing set. |
