Autonomous Density GAMMA-GAMMA Logging APGGK-90RI

(Equipment / Material)
Model Number: АПГГК-90РИ
Condition: New
Location or Storage Country: Russia
Service Engineering Support: Yes
Warranty: No
Price: Call for price
Description:
Designed for GIS using the method of compensated density gamma-gamma-ray logging.
Overview:

It is used to study very shallow and horizontal sections of the trunk of oil and gas wells filled with flushing fluid based on oil and water.

Tasks to be solved:

  • correlation of well sections and lithological changes;
  • detailed lithological dissection;
  • stratigraphic studies;
  • determination / refinement of filtration-capacitive properties;
  • determination / refinement of the mineral composition of rocks.

The device is designed to work with a cesium-137 gamma radiation source with an activity of 6.65 × 10 9 to 3 × 10 10 Bq. Gamma-ray detectors - scintillation detectors with PMT.

It is equipped as standard with a free rotation unit, which allows turning the drilling tool during research.

The APGGK-90RI device is manufactured with a recoverable source . This design allows in case of an accident not to leave radioactive sources in the well.
The new design of the device and the developed probe allow to obtain the quality of the material, not inferior to the quality of the work of the instruments on the wireline.
