Quartz Pressure Single

$0.00

DESCRIPTION   Quartz Pressure Single   The CNPS Quartz Pressure Tool uses an industry standard precision quartz crystal pressure transducer. The tool measures pressure and gauge temperature.

Category:

OPERATING PRINCIPLE

Wellbore pressure is transmitted through an isolating metal bellows to a volume of silicone oil which surrounds the quartz pressure crystal. Changes in hydrostatic pressure alter the resonant frequency. A second crystal, not subjected to external pressure, provides temperature compensation and allows calculation of precision, high resolution, pressures.

 

APPLICATIONS

Draw-Down and Build-Up Pressure Transient Analysis.

• Down-Hole Pressure Gradient Measurement. INTERFACING & TOOL COMBINATIONS Mbus, SRO (surface readout) or Ultrawire™ Mbus QPS interfaces direct to MPL, XMW and XSH telemetry tools It may be used for memory or SRO logging. SRO QPS may be placed anywhere in the string and can combine with a second Ultrawire QPS may be placed anywhere in the string and can combine with other It may be used for memory or SRO logging. Sondex Compatible and OPTIONS Ultrawire ™ toolbus (UW) or Memory toolbus (Mbus) Slickline memory or surface readout mode (with suitable telemetry controller)
