“QUANTOR-5micro” measuring recorder
The portable compact “QUANTOR-5micro” measuring recorder promptly monitors fluid level, annulus pressure and downhole pump operation.
Description
The “QUANTOR-5micro” has a split design enabling to perform several types of examinations (echogram, CEF, dynagraph, valve test) with a single instrument. All “QUANTOR-5micro” sensors are interchangeable.
For standard thread 60х2.54 mm
Installed instead of pressure gauge (thread М20х1.5 mm)
Two level gauge versions are available:
No mechanical switches are designed which significantly increases reliability under severe operating conditions.
All level gauge components in contact with aggressive medium are made of corrosion resistant materials.
Each recorded echogram may be a means for clarifying sound velocity along tubing collars which improves the accuracy of fluid level determination.
All sensors are equipped with high-capacitance detachable lithium batteries.
No heating is required since a high-resolution frost-proof colour display is installed in the recording unit. This extends battery life.
Measurement results automatic saving to the instrument non-volatile memory.
The instrument is leak-tight and can be operated under various weather conditions.

Measurements
A sensor unit (an echometer) installed on the wellhead process nipple measures fluid pressure and level in the well annulus. An acoustic sensor and a pressure sensor are installed in the echometer casing. The sensor sensing elements are safely isolated from external aggressive environment.
A valve for bleeding a gas portion or an acoustic pulse generator is mounted in the echometer depending on whether overpressure is detected. The pulse generator creates a sounding signal whose level is sufficient for echo metering of almost any well.
Echogram recording is controlled by one key. A plot is displayed on the recording unit in the real-time mode. After recording, the operator can process the echogram without transmitting it to the computer.
The instrument supports several sound velocity determination methods:
In practice, it may be hard to identify a reflected pulse on the background of high noise amplitude in the well annulus. In that event, the system can suppress noise and amplify a desired signal. A high-frequency component is removed from the recorded signal by a mathematical filter.

The instrument supports several sound velocity determination methods:
- In the tubing collars identification mode
- Calculation based on annulus pressure
- According to pressure/velocity chart
- Keyboard input

The dynamometer testing system records dynagraphs, leakage curves (valve test) and measures a load on the polished rod without measurement recording.
A horseshoe transducer or a polished rod transducer is used for dynagraph recording. The polished rod transducer is attached to the polished rod and designed as a clamp with a clamping screw. The clamping screw serves for polished rod transducer quick installation without tightening torque adjustment. To record measurement results, it is enough to indicate two successive positions of the polished rod at the bottom dead centre. The transducer traces a change in the rod diameter under a variable load, thus determining a relative load variation on the rod. The rod position is calculated using the measured acceleration.
The polished rod transducer minimizes the examination time and covers a larger well stock, but along with these advantages, the polished rod transducer has some great disadvantages:
The jacks neither release the cable hanger nor damage the polished rod.
The horseshoe transducer measures loads and movements in a direct way. After transmission to the computer, the resulting dynagraph allows performing a qualitative analysis of the equipment performance. Quality of a dynagraph obtained by the horseshoe transducer is in no way inferior to quality of this type of examination performed by the “QUANTOR-5Rshgn” diagnostic complex.

The polished rod transducer minimizes the examination time and covers a larger well stock, but along with these advantages, the polished rod transducer has some great disadvantages:
- The transducer cannot record absolute loads and movements.
- The load value is affected by the polished rod curvature due to misalignment of the wellhead equipment.
