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.
