Rupture Disk Tubing String Tester Ball Valve For Drill Stem Testing Tools
The Rupture Disk Tubing String Tester Ball valve is a full-opening valve used to pressure-test the work string while running in the hole. The valve is operated after it is stung into a permanent packer or a retrievable packer is set. The valve requires a differential pressure between the annulus and the tubing to burst the rupture disc.
In downhole operation, the valve can not be closed after open.When running in the hole, the tester valve must run in downhole in opening condition, after string testing finished, increasing annulus pressure made the Rupture disc burst
The RD Tubing String Tester Valve consists of:
• Ball valve section
