5" x 15000 psi Cased Hole Downhole Tester valve
Cased hole tester valve for drill stem testing operation in high pressure
Introduction of the Downhole tester valve
The Downhole Tester valve is a full-opening, annulus pressure operated DST tool. With applied pressure, the tool can be locked open and then returned to the normal operating sequence at any time. This Downhole tester valve is the select tester valve, which has the capabilities of taking multiple downhole closures where pipe manipulation is restricted and a full opening string is desired. The select tester valve has the same basic features of the 15K LPR-N Tester valve and been improved.
How to operated the Ball valve in Select tester valve?
The ball valve operates independently of pressure changes from operations such as acidizing and fracturing. This gives theTester valve greater compatibility and flexibility with other tools in the string.It is fully balanced to annulus pressure and will remain in the closed position while tripping in hole. Operation of the FBTV insensitive to tubing pressure changes
What parts are included in the select tester valve?
The select tester valve is composed of four basic sections; ball valve section, upper hydraulic section, nitrogen section and the metering section.
