Fixed wet connection system for an electrical submersible pump

摘要

A wet connection system comprises a fixed tubing with an orientation profile and redundant, first and second fixed wet connectors, and an electrical submersible pump assembly (ESP) comprising a wet connector and an orientation element for engaging the orientation profile. The ESP can be reconfigured, for example, by interchanging its component modules so as to change the position of its wet connector with respect to the orientation element, whereby the wet connector on the ESP can be engaged alternatively with either one of the fixed wet connectors when the orientation element is engaged with the orientation profile in the same deployed position of the ESP.

主权项

1. An apparatus for use in a well,
the well including a wellhead and a power supply at the wellhead, the apparatus comprising: a tubing disposed in the well, the tubing including an orientation profile; at least one first wet connect contact and at least one second wet connect contact, the first and second contacts arranged fixedly to the tubing and connected by at least one cable to the power supply, the first and second contacts spaced apart in a longitudinal direction of the tubing; and an electrical submersible pump assembly (ESP), the ESP including at least one pump, at least one electrical motor for driving the pump, a corresponding ESP wet connection part, and an orientation element; the ESP being deployable and recoverable via the tubing and wellhead to and from a deployed position in which the ESP is oriented by engagement of the orientation element with the orientation profile; wherein the ESP is selectively configurable in a first configuration in which in the deployed position the at least one motor is connected to the power supply via the at least one first contact but not the at least one second contact, and a second, alternative configuration in which in the deployed position the at least one motor is connected to the power supply via the at least one second contact but not the at least one first contact, and such that ESP may be powered in normal use in either one of the first and second configurations.
