    摘要： Systems, program product, and methods for monitoring linearity of a down-hole pumping system assembly during deployment within a bore of a casing of a well positioned to extract hydrocarbons from a subterranean reservoir and selecting an optimal operational position for the down-hole pumping system assembly within the bore of the casing, are provided. Various embodiments of the systems allow an operator to ensure that a motor and pump of a down-hole pumping system assembly are installed in an optimal position in a well by ensuring alignment across the pump stages casing and motor casing. The system includes a groove extending along an outer surface of a housing of the pumping system assembly, and an optical sensing fiber mounted in the groove.

    摘要： A centrifugal pumping system having a stack of impellers and diffusers for pressurizing fluid. The impellers are rotated by a motor for pressurizing and lifting fluid from within a wellbore. Undulating profiles are provided on leading edges of the impellers for inducing turbulence in the fluid being pumped. Increasing turbulence better homogenizes the fluid, so that choked flow is avoided when different density components are present in the fluid. Reducing the possibility of choked flow increases pump efficiency and lift capacity.

    摘要： Systems and methods for installing an optical fiber in a downhole equipment system having multiple components that are installed in the field. Components such as sections of an ESP motor are assembled, forming a continuous sealed conduit that extends through the components. The conduit is sealed to prevent potentially damaging fluids from leaking into the conduit. After the conduit through the components is formed, an optical fiber is inserted into the conduit so that the fiber spans the connections between the components. The optical fiber may incorporate multiple sensors (e.g., fiber Bragg gratings) that can sense parameters such as temperature at multiple points in the different components. The passageways through the different components may have different diameters or tapered/chamfered edges to facilitate insertion of the optical fiber in the conduit.
