摘要：A rotating control device (RCD) can include an automatic RCD oiling system forproviding lubricating oil to the RCD and preventing wellbore fluid under wellborepressure from entering the RCD. The automatic RCD oiling system can include an oil
pressure intensifier, a pump, and a pump flow controller. The oil pressure intensifier caninclude a piston assembly for maintaining a pressure differential between pressure fromthe lubricating oil on a rod side of the piston assembly and an annulus pressurecorresponding to a wellbore pressure on the piston side of the piston assembly. Thepump can pump lubricating oil from tank into passages to a bearing assembly of the RCDand a pump flow controller that controllably directs lubricating oil to the pistonassembly and a return passage to the tank or the pump.
