发明名称 Self lubricating submersible pumping system
摘要 A lubrication technique for one or more components used in the production of subterranean fluids. The technique comprises the separation of particulates from a produced fluid having lubricating ability. Following separation of the particulate matter, the lubricating fluid is directed to specific areas, such as bearing surfaces within a submersible pump, to facilitate continued operation of the overall system.
