Abstract
An electrical submersible well pump assembly supported on a continuous length of coil tubing. An electrical cable extends through the coil tubing from the pump assembly to the surface for supplying electrical power to the pump assembly. The cable is of lesser diameter than the inner diameter of the tubing, resulting in an annulus. Standoff members locate in the annulus to centralize the cable. Standoff members frictionally engage the inner diameter of the tubing and the outer diameter of the cable to transfer weight of the cable to the coil tubing. Flow passages extend through the annulus surrounding the cable to enable lubricant and coolant fluid to be pumped from the surface to the pump assembly.
