Ball Valve Section / Metering Section of Downhole Select Tester
Valve
The Full Bore Downhole Tester Valve is the Select Tester Valve in
Halliburton, which is an annulus pressure controlled ball valve and
is designed to allow multiple cycles during cased hole testing and
perforating operations.
The downhole 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 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.
