ORZ1 downhole monitoring system

Purpose

The system monitors volume of fluid injection for each formation during the development of oil fields with dual injection of water into two product horizons. Joint development with OOO NPF Packer.

System components

  • surface readout unit ASPT-KV-ORZ
  • mechanical choke
  • flow meter RM-20
  • cable communication line

Monitored parameters

  • formation fluid pressure
  • formation fluid temperature
  • injected fluid temperature
  • injected water volume

Principle of operation

The measuring module is installed below the choke that regulates the injection into the upper and lower formations, and is connected to a high-temperature geophysical cable, or, in the second version, an ESP power cable can be used. The cable passes through the cable entry through the ground fittings and is connected to the surface readout unit.

Advantages

  • ability to pump water into several formations through one well
  • measurement of the volume of injected water and measurement of formation pressures in real time
  • reduction of costs during construction and operation of waterflooding system in oil fields
