KUM Mechanical Equalizing Valve (rated to 70 MPa)




It is designed to equalize the pressure in the annulus above the packer and the pressure inside the tubing string.

DESCRIPTION APPLICATION

  • it is used in combination with a packer during hydraulic fracturing and other well operations after which circulation between the tubing annulus and interior is mechanically generated.

ADVANTAGES

  • it provides easy packer releasing after hydraulic fracturing or other well operation;
  • the valve has a spline joint that provides torque transmission via tubing string to the equipment installed below it;
  • this valve can be used multiply during one round-trip operation;
  • it eliminates complications while packer releasing in multi-packer BHAs caused by significant pressure differences above and below a packer.

DESIGN FEATURES

  • the valve is mechanically actuated by tensioning the tool upwards;
  • the valve actuation force is adjusted by the manufacturer upon the customer’s request;
  • the valve is closed by unloading the tool.

TESTIMONIALS:

  • Testimonial from OJSC “TNK-Nizhnevartovsk”

  1. THE VALVE IS CLOSED (Tubing pressure)
    The valve is closed by unloading the tool on it.
  2. THE VALVE IS OPEN (Annulus pressure)
    The valve is open to equalize pressure after the tool is tensioned upwards by the force exceeding the specified (preset) actuation force taking into account the weight of the equipment that has been run in.
