Downhole Tester Valve Working Pressure 15000 Psi For Well Testing Service
The downhole tester Valve is used for drill stem testing service. There are two types of downhole tester valve we supplied including select tester valve and LPR- N valve. The select tester valve is a full opening, annulus pressure operated tool used in cased holes. This tool has the capabilities of taking multiple downhole closures where pipe manipulation is restricted and a full opening string is desired
Structure of downhole tester valve - 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.
* The ball valve section contains the ball valve and the mechanism that rotates the ball when the tool is activated; the ball is rotated to the open
position allowing the reservoir to flow into the testing string.
* The upper hydraulic section is contained between the upper annulus ports and the nitrogen filler valve. The critical part of this section is the
metering (power) cartridge and selector.
* The nitrogen section is composed of the nitrogen case, nitrogen mandrel, floating piston and nitrogen filler valve. The nitrogen acts as an
adjustable spring and provides the force needed to close the ball valve.
* The metering section is composed of the lower oil chamber, metering cartridge and floating piston. The oil in this section acts as a barrier
between the tool and the annular fluid. This insures that only clean fluid passes through the metering cartridge
