KCM Multiple-use Circulating Valve (rated to 70 MPa)




It is designed for sealed separation and communication between the annulus and the interior of tubing.

DESCRIPTION APPLICATION

  • in emergency situations to kill the well when used jointly with a packer;
  • in combination with a packer during formation hydraulic fracturing as well as various well operations in the course of well completion and operation.

ADVANTAGES

  • these valves can be used multiply for one tripping operation;
  • proven by years of successful application experience;
  • low price;
  • high repairability.

DESIGN FEATURES

  • the valve is opened by generating annulus pressure that exceeds the pressure inside the valve and the tubing.

TESTIMONIALS

  • Testimonial from “TatneftLeninogorskRemServis” Ltd.

1 when placing an order for equipment for Т=150°С, please indicate Т150.

2 Pressure differential required to initially open the valve can be modified upon the customer’s request within the range of 6 to 16 MPa.

1. THE VALVE IS CLOSED

2. THE VALVE IS OPEN

The valve is open after generating the initial annulus pressure which exceeds the inner tubing pressure. This causes the ring to break, the piston to move downwards and circulating ports to open. To keep the the valve further open a pressure difference of 2±1 MPa must be generated.

3. THE VALVE IS CLOSED

The valve is closed after equalizing the pressure between the tubing annulus and interior. The spring brings the piston back to its initial position, the circulating ports are shut off.
