BACKSPIN MONITOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18099686 titled 'BACKSPIN MONITOR

Simplified Explanation: Electric motors used in oil and gas applications to drive downhole submersible pumps can experience backspin when the pump is shut down, causing potential damage to the motor and posing a shock risk to personnel at the surface. The present systems and methods aim to minimize these risks by detecting backspin events and preventing the re-initiation of motor operation until after backspin has ceased.

Key Features and Innovation:

  • Detection of backspin events based on phase angle differences at the three phases of the permanent magnet motors.
  • Alerting relevant personnel to prevent re-initiation of motor operation until after backspin has ceased.
  • Minimization of potential damage to the drive shaft and shock risks to personnel at the surface.

Potential Applications: This technology can be applied in various oil and gas operations where downhole submersible pumps are used, ensuring the safe and efficient operation of electric motors in such applications.

Problems Solved:

  • Prevents damage to the drive shaft of electric motors caused by backspin events.
  • Reduces the risk of electric shock to personnel at the surface during backspin.

Benefits:

  • Enhances the safety and reliability of electric motors in oil and gas applications.
  • Minimizes downtime and maintenance costs associated with motor damage due to backspin events.

Commercial Applications: Potential commercial applications include oil and gas companies utilizing downhole submersible pumps with electric motors, as well as manufacturers of such equipment looking to enhance the safety features of their products.

Questions about Electric Motor Backspin Detection: 1. How does the technology detect backspin events in electric motors used in oil and gas applications? 2. What are the potential risks associated with backspin events in electric motors, and how does this technology address them?

Frequently Updated Research: There may be ongoing research in the field of motor control systems and safety features for oil and gas applications, which could further enhance the effectiveness of backspin detection technologies.


Original Abstract Submitted

Electric motors are used in oil and gas applications to drive downhole submersible pumps. Upon shutdown of such pumps, a column of fluid remains thereabove. When power is removed, the fluid flows back down the casing causing the motor to rotate backward and generate a voltage that is applied up the power cable to the surface. If the motor is restarted before backspin ceases, damage to the drive shaft is likely. Additionally, the up-hole applied voltage during backspin can pose a shock-risk to personnel at the surface. The present systems and methods minimize these risks by identifying backspin events based on determining phase angle differences at the three phases of the permanent magnet motors and alerting relevant personnel and otherwise preventing re-initiation of motor operation until after backspin has ceased.
