Measuring Operational Parameters in an ESP Seal with Fiber Optic Sensors

摘要

A seal section for use in a wellbore electrical submersible pump and includes an optic fiber detection arrangement wherein one or more optic fiber sensors is used to detect an operational parameter associated with the seal section. The operational parameters can include temperature, vibration and pressure.

1. A seal section for use in pressure equalization in an electric submersible pump, the seal section comprising:
an outer housing defining a plurality of fluid-equalizing labyrinth chambers that are axially separated from each other by at least one bulkhead; a power transfer shaft retained by the housing and rotatable within to transmit rotational force from a motor section to a pump section within the electric submersible pump; and an optic fiber associated with the seal section to detect an operational parameter associated with the seal section.
