摘要： An electric submersible pump (ESP) assembly. The ESP assembly comprises a seal section that comprises a housing and at least one sacrificial anode assembly. The at least one sacrificial anode assembly comprises a sacrificial material suitable to attenuate the corrosive effect of H2S fluid (hydrogen sulfide) and comprises a containment disposed inside the housing. The containment defines an annulus between an outside of the containment and an inside of the housing. The containment is disposed around the sacrificial material. The containment defines interiorly an initially void space downhole of the sacrificial material. The at least one sacrificial anode assembly defines a folded fluid flow path through the sacrificial material.

摘要： A downhole electric submersible pump (ESP) assembly. The downhole ESP assembly comprises a hybrid permanent magnet motor (PMM) comprising a first drive shaft, a stator, and a rotor comprising a first permanent magnet element, a second permanent magnet element, and an induction squirrel cage, wherein the rotor is mechanically coupled to the first drive shaft and disposed within the stator; a seal section having a second drive shaft coupled to the first drive shaft; and a pump assembly having a third drive shaft coupled to the second drive shaft.

摘要： An electric submersible pump (ESP) seal section assembly. The assembly comprises a seal section filled with dielectric oil; a coupling body partially inserted into the seal section, and a coupling body, wherein the coupling body is substantially cylindrical and has a first outside diameter at an upper end of the coupling body, has a second outside diameter smaller than the first diameter below the first outside diameter, has a circumferential tapered shoulder between the portion of the coupling body having the first diameter and the portion of the coupling body having the second diameter; a service-less flange coupled to the seal section, wherein the service-less flange defines a circumferential opening having a circumferential tapered shoulder on an upper edge that contacts the circumferential tapered shoulder of the coupling body.
