IRZ TMS Downhole sensor system with thru shaft

Purpose

Monitoring and performance optimization  of Electrical Submersible Pump (ESP) in the systems of “inverted type” and systems for dual completion on the scheme ESP-motor-ESP

System components

  • downhole sensor (DHS)
  • TMS-E5 or ASPT surface unit

Monitored Parameters

  • pressure at the intake of the pumping unit
  • motor oil temperature
  • formation fluid temperature
  • motor vibration level
  • insulation resistance of the power cable and the motor

The usage  of IRZ TMS allows ESP operation’ managing systems to provide the following:

  • protection and optimization of ESP operation
  • automatic holding of a given liquid level in a well
  • data acquisition for well hydro-dynamic testing

Principle of Operation

The downhole sensor is mounted between the motor and the seal section. It does not require additional outer cables for connection.

Advantages

  • excess voltage protection in case of power cable’ or motor’ short circuit failure up to 5000V
  • compatible with any control station (drive) of national production
