摘要: An electric submersible pump having a housing with side walls and at least one stackable diffuser residing within the housing. The stackable diffuser can have a diffuser side wall forming an annular gap between the outer surface of the diffuser side wall and the inner surface of the housing side wall. A filler can be provided within the annular gap to prevent recirculation and/or rotation of the diffuser within the housing. Additionally or alternatively, an O-ring can be disposed within the annular gap to prevent recirculation and/or rotation of the diffuser within the housing.

摘要: A downhole sensor position adjustment device on a downhole sensor assembly comprising a set of centralizers and a sensor array coupled to an adjustable framework radially positionable by an actuator. The actuator includes an extend-retract mechanism to radially position the sensor array a predetermined radial distance to an inner surface of a casing. A controller communicatively coupled to the extend-retract mechanism is configured to actuate the extend-retract mechanism. A positioning sensor provides feedback of the predetermined radial distance of the sensor array to the inner surface of the casing.
